Abstract

Blastopsylla occidentalis Taylor (Hemiptera: Aphalaridae), native to Australia, causes damage to an increasing number of Eucalyptus (Myrtaceae) species and their hybrids in a growing number of countries. This is partly because predatory insects and spiders have low potential to reduce B. occidentalis populations. The purpose of this study was to report a new host of B. occidentalis and the parasitism of this insect by Psyllaephagus blastopsyllae Tamesse, Soufo, Tchanatame, Dzokou, Gumovsky, & Coninck (Hymenoptera: Encyrtidae) in Indonesia. Blastopsylla occidentalis nymphs parasitized were collected from five Eucalyptus pellita F. Muell. trees on October 3rd, 2023, in Senoni, East Kalimantan, Indonesia, and reared in a laboratory until their adults or P. blastopsyllae emerged. The adults recovered from this parasitoid were identified by morphological analysis of their bodies. Eucalyptus pellita is a new host for B. occidentalis. This is the first time in Asia (Indonesia) that P. blastopsyllae has been reported. This new insect-host association alerts the world to the need to develop management strategies for B. occidentalis on E. pellita plantations. The recovery of P. blastopsyllae also opens up new perspectives for the development of biological control programs in Indonesia.

Abstract

Fall armyworm (FAW), Spodoptera frugiperda (Smith) is an important pest on maize. Common control carried out by farmers in controlling the pest is by using synthetic insecticides. However, the improper use of synthetic insecticides can cause negative impacts. One strategy to control pests that is safe and environmentally friendly is by using botanical insecticides. Soursop (Annona muricata) leaves, yam bean (Pachyrizus erosus) seeds, and Javanese long pepper (Piper retrofractum) extracts are known to be able to control various insect pests. The aim of this research was to study the effectiveness of soursop leaves, yam bean seeds, and Javanese long pepper extracts on mortality of second instar larvae of FAW. Two test methods used to assess the three extracts on the mortality of S. frugiperda larvae were the leaf residual and the topical application methods. Insect mortality levels were processed using probit analysis to obtain lethal concentration (LC) and lethal dose (LD) values for each extract. The results showed that P. retrofractum extracts showed highest mortality effect on S. frugiperda than P. erosus and A. muricata extracts both on leaf residual and topical application methods. The LC50 and LC95 values of P. retrofractum extract were 0.142% and 0.595%, respectively. Meanwhile the LD50 and LD95 of P. retrofractum extract 0.10 µg/larvae and 0.40 µg/larva, respectively.

Abstract

Information on demographic statistics of Menochilus sexmaculatus (Fabricius) on Aphis craccivora Koch is important for the development of more effective and environmentally friendly pest control strategies. The objective of this experiment was to determine the demographic statistics (survival, fecundity, growth rate, reproductive rate, length of life), biological and morphometric of M. sexmaculatus on A. craccivora prey. A total of 15 pairs of M. sexmaculatus adult obtained from broad bean fields in Situgede, Bogor were reared in cages containing 3 polybags of broad bean plants (infested with A. craccivora as food for adult). One hundred eggs (6 egg batches) were collected from the cages and reared in plastic containers (top diameter 6.7 cm, bottom diameter 4.9 cm, height 6.3 cm) per 1 egg batch. Larvae that emerge from the egg are separated individually into 1 container and reared until the adult produced eggs again and died. Mean values and standard deviations of 5 demographic statistical parameters were determined using the Jacknife method. Survival probability and paternity were presented as curves. M. sexmaculatus had a mean body size of 7.32 × 5.94 mm for males and 8.63 × 6.98 mm for females.  M. sexmaculatus has potential as a control agent for the pest A. craccivora. This potential is supported by its high reproductive ability (R0 35.72 ± 1,10 individuals/female/generation and GRR 128.85 ± 3.02 individuals/generation), fast population growth rate (r 0.20 ± 0.002 individuals/female/day), T which is 18.16 ± 0.04 days.

Abstract

The dwarf honey bee Apis florea Fabricius, was successful coexistence with larger bees, Apis cerana Fabricius and Apis dorsata Fabricius in Bangalore, India. However, there is a lack of A. florea foraging behavior that shared the same plant resources with A. cerana and stingless bee Tetragonula laeviceps (Smith) in Indonesia. This study investigated the foraging activities of two honey bee species (A. florea and A. cerana) and the stingless bee T. laeviceps, which live sympatrically and also seek environmental factors that influence the foraging behavior of bees. The flight activity was recorded on the bee farm at Jombang Regency, East Java Province, from 06.00–16.00 hours for three consecutive days. Environmental factors of temperature, humidity, and light intensity in open and close to the nest areas were recorded. This study reported that A. florea started foraging activity at 09.00, while A. cerana and T. laeviceps started to forage earlier, at 06.00 in the morning. Therefore, the foraging activities of bees in East Java, revealed temporal resource partitioning, which confirmed the results of a previous study in Bangalore. The temperature and humidity mainly influenced the foraging activity of the three bee species (P<0,001). Temporal resource partitioning in A. florea suggests a foraging strategy that coexists with sympatric honeybees and stingless bees. The high flight activity of A. florea at midday suggests that this species can adapt to high temperatures. This result implies that A. florea could be a potential future pollinator in tropical regions facing the issue of a warming climate.

Abstract

Maize is an important staple food in Indonesia that is threatened by the main pest Spodoptera frugiperda (Smith), including on Sumbawa Island which is one of the centres of dryland maize production in Indonesia. Currently, S. frugiperda control still relies on synthetic insecticides because the potential of natural enemies is not widely known, especially in dryland maize crops on Sumbawa Island. This study aims to assess the potential of S. frugiperda parasitoids including diversity, evenness, dominance, richness, and parasitization rate. Samples were collected by purposive random sampling in February–May 2024 in dryland maize crops at the age of 4–6 weeks after planting on both farm that applied insecticide and farm without insecticide. A total of 30 plants with common symptoms of damage due to S. frugiperda attack in three plots each measuring 10 m × 10 m were carefully examined to collect 30 egg clusters and 30 larval individuals. The results found egg parasitoids Telenomus remus Nixon and Trichogramma nr. pretiosum Riley, larval parasitoids Exorista sp., larval-pupal parasitoids Brachymeria lasus Walker and Archytas marmoratus Townsend. We concluded that the egg parasitization was dominated by T. remus (23.54-61.22%), which has potential as a biological agent for S. frugiperda. Larval parasitization was dominated by Exorista sp. (50%), but the high parasitization rate was overshadowed by hyperparasitoid which may reduce its effectiveness as a biological agent for S. frugiperda.

Abstract

The fall armyworm, Spodoptera frugiperda (Smith), has been problematic in Southeast Asia since its invasion in 2019. Fall armyworm management in these areas largely depends on synthetic insecticide application, and alternative management practices are very few and impractical. The demand for new and more sustainable tools for managing this pest has increased. In this study, we tested the mating disruption (MD) efficacy of fall armyworm sex pheromone in low-density polyethylene dispensers containing 2.5 g of blended active ingredients, (Z)-9-tetradecen-1-yl acetate (Z9-14Ac) and (Z)-11-hexadecen-1-yl acetate (Z11-16Ac) in a ratio of 87:13. The primary objective was to evaluate the optimal density of the dispensers/ha and understand the benefits of MD in reducing the damage caused by fall armyworm and associated insecticide applications as compared to conventional growers’ practices in Indonesia and Thailand. Research was conducted at 16 locations across Indonesia and Thailand in 2020 and 2021 in 9-ha treatment plots and compared to conventional growers practice. Trap reduction, a measure of MD, was significantly higher (74–90%) with 30 dispensers/ha than with non-dispenser areas, suggesting high levels of mating suppression. MD’s primary benefit is damage reduction, where 30 dispensers/ha reduced damage caused by fall armyworm larvae by 34–35% while simultaneously enabling a greater than 50% reduction in insecticide usage compared to the conventional growers’ practice. Our results show the effectiveness and feasibility of MD using pheromones as an essential management tactic for fall armyworm. These results represent a potential step towards more efficacious and sustainable pest management in Southeast Asia.

Abstract

Changes in the function of natural areas, rice fields, and plantations can reduce the number and diversity of butterflies, with environmental factors playing a significant role in shaping butterfly richness and diversity. This study aimed to identify differences in butterfly diversity and composition between natural and modified habitats and to examine the relationship between environmental factors and butterfly richness and diversity. This research was conducted from March to April 2021 using a modified exploration method (pollard walk) through direct observations of butterflies. Observations were conducted in two sessions from 08:00–12:00 and 13:00–17:00. The results of this study successfully found five butterfly families with 995 individuals in natural habitats (79 species), whereas, in modified habitats, as many as 627 individuals (29 species) were documented. Based on the Shannon Winner index (H’) and Margelaf richness index (R), the natural habitat was classified as high (H’ = 3.84, R = 11.2). Simpson’s index and evenness values of the two habitats were too different and classified as high. There were significant differences in butterfly abundance between the natural and modified habitats (t (164) = 2.441, p = 0.016). Among the biotic factors examined, only wind speed significantly affected butterfly abundance.

Abstract

One of the main problems in the cultivation of Brassicaceae vegetable plants is the attack of diamondback moth Plutella xylostella (Linnaeus). Extracts of Piper aduncum and Aglaia odorata have the potential to be used as botanical insecticides because they contain compounds that are toxic to insects. This study aims to evaluate the toxicity and feeding inhibition activity of hexane-extract of P. aduncum fruits and methanol-extract of A. odorata twigs against second instar larvae of diamondback moth. Extraction was carried out using the maceration method with a powder-to-solvent ratio of 1:10 (w/v). The diamondback moth insects used were from colonies reared in the laboratory. The lethal effect test was conducted using the leaf-dip method with test concentrations equivalent to LC15, LC35, LC55, LC75, LC95, and a control. The feeding inhibition test was conducted using the choice-test method with test concentrations equivalent to LC15, LC35, LC55, and a control. The results show that the hexane-extract of P. aduncum fruit is more toxic to second instar P. xylostella larvae than the methanol-extract of A. odorata twigs based on the probit analysis value of the relationship between concentration and mortality. The LC50 and LC95 values of P. aduncum extract were 0.07% and 0.14%, respectively, while the LC50 and LC95 values of A. odorata extract were 1.63% and 4.72%. Additionally, P. aduncum and A. odorata extracts also exhibited feeding against diamondback moth at concentrations of 0.07% and 1.77%, respectively. The combined effects of direct toxicity and feeding inhibition contributed to the mortality of the test insects. Thus, these two extracts, escpecially P. aduncum extract wich demonstrated higher effectiveness, have a great potential as botanical insecticides for controlling diamondback moth in Indonesia.

Abstract

The yellow stem borer, Scirpophaga incertulas (Walker) is a major nocturnal pest of rice. Presence of S. incertulas moth had a flight peak during the lunar period and affects its reproductive status. The purpose of this study was to analyze the critical time in the lunar period related to the highest reproductive status of S. incertulas in the field. Monitoring of moth populations were carried out by setting up two traps equipped with 60-watt LED lights (800 lm) on farmers’s fields in Rawamerta District, Karawang Regency, West Java. Moth trapping was carried out once an hour, started 6–10 PM, for three days on lunar period. The observation were conducted during the nursery, maximum tillering, and grain filling phases. upen capture, females were transferred to rearing cages until they laid all their eggs. Moth reproductive status, fecundity, and fertility were counted and analyzed. Total of captured female S. incertulas moths in the lunar period from three phases of rice was 216 individuals. In the nursery phase, the highest population level was obtained at 8 PM at 27.8%, While the maximum tillering and grain filling phase were 39.3 and 29.1% at 7 PM. The highest population level of virgin, mating, and post-oviposition moths was obtained at 7 PM, at 10,94, 12,52, and 9,64%. The highest average fecundity occurred at 6 PM with 42 eggs/group and the highest fertility was 45,8% at 8 PM. The highest critical reproductive time of female S. incertulas moths occured between 6–8 PM.

Abstract

Spodoptera frugiperda (Smith), known as fall armyworm (FAW), originating from America that devastates corn crop, causing up to 50% damage to corn crops in Bali. Molecular identification of strain diversity using mitochondrial cytochrome oxidase subunit I gene (mtCOI) and triosephosphate isomerase gene (Tpi) markers also population density monitoring are a fundamental method for monitoring, detecting and controlling these pests. This research aims to determine FAW strain based on COI and Tpi markers and their population density analysis at representative sites in Bali. This study involved several stages: samples collection; DNA extraction; amplification, visualization; Population density observation and sequencing; and data analysis. Data were analyzed using GeneStudio and BioEdit for editing and alignment, and MEGA 11 for constructing phylogenetic tree. Sequence analysis based on COIB indicated that samples from Bali comprised of 41.67% rice strains and 58.33% corn strains, with 100% of corn strain  haplotypes being h4 FAW [FL] from Florida. Based on Tpi marker, 100% of the samples were identified as corn strains with haplotypes Ca1 and Ca2. This study found that the FAW diversity in Bali consists of two strains and one haplotype based on COI (COI-R and COI-Ch4), while based on Tpi, there is only one strain  with two haplotypes (Tpi-Ca1 and Tpi-Ca2). The highest population density of FAW was observed in the Tabanan plot, with 6,8 larvae/sample unit. Early instar larvae (2–3) were predominant in 3 WAP whereas late instar larvae (4–6) were predominant in 5 WAP.
