Abstract

Landscape management in an agroecosystem is part of an ecological approach aimed at conserving biological control to suppress the abundance of pests and crop damage. This study investigates how agricultural landscape composition influences the abundance and attack rates of Spodoptera frugiperda and its parasitoids’ abundance and parasitism rates. The research assessed landscape characteristics in maize fields around Bogor, including class area (CA) and the number of patches (NP) of agricultural and semi-natural habitats. A 300-meter radius buffer was used to evaluate these features. Eggs and larvae of S. frugiperda were collected and reared in the laboratory to observe their parasitized and non-parasitized development. The influence of landscape composition on the abundance, attack rate, and parasitism of S. frugiperda was analyzed using generalized linear models. The results indicate that landscape composition affects the abundance and attack rate of S. frugiperda and influences the abundance and parasitism rate of parasitoids. Increasing the agricultural class area can increase the abundance of S. frugiperda larvae. In addition, increasing the NP and CA of semi-natural habitats can reduce the infestation rate of S. frugiperda. The elevation of maize areas also shows an influence on the abundance of parasitoids and the parasitism of larvae. In contrast, the age of the maize affects the abundance and attack of S. frugiperda. These findings highlight the importance of landscape composition, particularly the presence of semi-natural habitats, in managing pest populations effectively. This ecological approach offers valuable insights for sustainable pest control strategies in agricultural practices.

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.
