Abstract

Side Effects of Deltamethrin Application to The Ground Surface Dwelling Predatory Arthropods on Soybean Field. Side effects of deltamethrin to the ground surface dwelling predatory arthropods were studied on soybean field in Cianjur during July to October 1998. Insecticide was applied 1-4 times. Predator abundance was observed by setting pitfall traps. The results showed that application of deltamethrin reduced the abundance of ground-surface predatory arthropods, especially lycosid and linyphiid spiders, carabid beetle and formicid. Reductions of predator abundance on the plots treated with deltamethrin were around 35% to 41%. There was no significant difference on the predator abundance among the plots treated with the insecticide at difference frequencies. Observations after application showed that predator abundance on the treated plots recovered one week after application. Deltamethrin application to the soybean with dense crown (38 and 52 days after planting) did not reduce predator abundance, especially within three day range after application. However, negative effects of deltamethrin application at early vegetative growth stage (10 days after planting) on the reduction of predator abundance continued by harvesting. The abundance of detritivorous arthropods was not affected by deltamethrin application.

Abstract

The coconut rhinoceros beetle (Oryctes rhinoceros L.) and brown rhinoceros beetle (Xylotrupes gideon L.) (Coleoptera: Scarabaeidae) are insect pests commonly found in oil palm plantations. Availability of breeding sites is one of factors that can increase the beetle population. Therefore, this study aimed to determine the abundance and age structure of the coconut rhinoceros beetles and brown rhinoceros beetles in the breeding sites located in a plantation with immature and mature stage of oil palms. The results of this study indicated that the abundance of coconut rhinoceros beetle was found to be lower than brown rhinoceros beetle (4.47±13.56 compared to 25.23±16.48 individuals/plot) in the oil palm plantations in PTPN VIII Parakan Salak, Sukabumi Regency. The population of coconut rhinoceros beetle was found in the breeding site located in the plantation with mature oil palms, but not found in the location with immature plants. The age structure of coconut rhinoceros beetle was dominated by the 1st and 2nd instar larvae. The age structures of brown rhinoceros beetles in the breeding sites located in the immature and mature oil palm were similar, and they were dominated by the 1st, 2nd, and 3rd instar larvae. Results of correlation analysis show that there is no correlation between soil chemical characteristics of the breeding site and the beetle population. Soil chemical characteristics at the breeding sites in both locations were relatively similar, and consequently, the abundance and age structure of coconut rhinoceros beetle and brown rhinoceros beetle not significantly different between both locations.

Abstract

Brown planthopper (Nilaparvata lugens (Stí¥l)) is one of the major rice insect pests that is known to cause high loss of rice production. One of the strategies to control this pest is by using resistant rice varieties. The aim of this research was to study the resistance of IPB 3S variety to BPH by measuring BPH fecundity, sex ratio, feeding activity as well as population increase compared to Ciherang variety against brown planthopper (N. lugens). Fecundity test used a pair of BPH adult infested on 21 days after planting (DAP) of rice plants. Eggs laid in rice stalks and the rest of eggs in the ovary were counted. In order to know the change of sex ratio, a pair of BPH adults was infested on 30 DAP rice plants and allowed to lay eggs. The calculation of sex ratio was conducted at adult stage of BPH by segregation between male and female adults. Feeding activity of BPH was evaluated using ninhydrin and analyzed qualitatively using spectrophotometer. Ten fourth instar nymphs of BPH was infested on 30 DAP old of rice seedlings. Honeydew secreted by BPH was collected to filter paper sprayed with ninhydrin. Population increased test was conducted by infesting five pairs of BPH adults on 35 DAP old rice plants. Observations was conducted on nymph and adult stages. Each test was replicated 10 times. In general, IPB 3S is slightly resistant to BPH, compared to Ciherang variety. The feeding activity of BPH is higher in Ciherang compared to IPB3S. However, the fecundity and population increased of BPH in Ciherang is similar to IPB3S.

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

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

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.

Abstract

The introduction of flowering plants into agricultural landscapes can significantly impact host-parasitoid food webs, although the extent of these effects varies depending on landscape characteristics. This study examined the effects of habitat manipulation by introducing flowering plants on the complexity of herbivore-parasitoid food webs in agricultural landscapes. Using Shannon diversity, links per species, linkage density, and vulnerability, we assessed the effects of flowers planted in maize fields. Herbivore collections were conducted at 2, 4, 6, 8, and 10 weeks after planting. Bipartite network analysis identified nine host morphospecies (Lepidoptera) in maize fields, revealing eight morphospecies in fields without flowering plants and six in fields with flowering plants. Eight major parasitoids were recorded, with Paratetracnemoidea sp.1 and Telenomus remus dominating fields without flowering plants, whereas T. remus was the most prevalent in fields with flowers. Spodoptera frugiperda emerged as the dominant host in both fields, whereas Lymantriidae sp.2 was present in low numbers in both field types. These results indicate that flowering plants enhance Shannon diversity and linkage density. However, the composition of the surrounding landscape can obscure these benefits, leading to simplified food web structures as the agricultural fields expand. Our findings underscore the significance of landscape context in shaping crop-herbivore-parasitoid interactions, offering valuable insights into sustainable agricultural management practices.

Abstract

Cheilomenes sexmaculata (Fabricius) is a potential natural enemy of aphids. Various aspects of the ecology and biology of this predator have been studied; however, there is still limited information on its physiology, particularly regarding pheromones and other semivolatiles. Naturally, intraspecific and interspecific interactions of C. sexmaculata involve a variety of semiochemicals. The information on the semiochemicals of C. sexmaculata, particularly its sex pheromones, footprints, defense mechanisms, aggregation, and other semivolatile characteristics, is still limited in Indonesia. This research was aimed to identify the semiochemical produced by the female of C. sexmaculata. The volatile compounds emitted by C. sexmaculata were captured using the headspace solid-phase micro extraction (SPME) method. The identification and quantification of each volatile compound were analyzed using gas chromatography-mass spectrometry (GC-MS). A total of 47 volatile compounds was identified among the semivolatiles. The identified volatiles comprise 47 compounds, mainly from the hydrocarbon compunds. Methyl isovalerate was the compound with the highest proportion, namely 31.43%. Several compounds identified were known to be components of the C. sexmaculata pheromone, namely methyl isovalerate, limonene, undecane, dodecane, and eicosane. These compounds were reported as components of sex pheromones, aggregation, and alarm. The limonene identified in this experiment was also previously reported in several Coccinelliade as a component of aggregation pheromone.
