Abstract

Indonesia has seen an increase and widespread reports of resistance among stored-product insect pests to phosphine. The use of Syzigium aromaticum (clove oil) as an alternative fumigant may be a useful strategy to control infestation by phosphine-resistant varieties of stored-product insects. The objective of this study was to examine the effectiveness of whole (unfractionated) clove oil as well as its component fractions as a fumigant and repellent against the red flour beetle (Tribolium castaneum (Herbst)), and to develop a simple fumigant formulation for this purpose. The experimental design used to test the effectiveness of clove oil and its fractionation was a completely randomized design (CRD). Meanwhile, testing the effectiveness of tablet formulations was carried out by factorial CRD. Fumigation test results gave LD50 and LD95 values of 0.234 and 1.142 ml/l respectively, for crude clove oil used in a fumigation chamber against T. castaneum. An n-hexane fraction of clove oil tested under the same conditions was more lethal, causing 95% mortality of T. castaneum at the dose of 0.801 ml/l during fumigation. Finally, tablets containing a set proportion of clove oil and naphthalene (1:1) reached LD91 against T. castaneum after 7 days’ fumigation.

Abstract

One of the recent organic waste management programs actively developed is organic waste bioconversion by using larvae of black soldier fly (Hermetia illucens (Linnaeus)). However, one major challenge in organic waste management in Indonesia is the limited space to manage the wastes at waste collection centers. This condition increases the number of wastes to be converted (consumed) by larvae of soldier fly. In this study, the condition was imitated in the laboratory where larvae were individually fed with a large number of wastes. Larvae were divided into 4 groups and were fed with 200, 300, 400, and 500 mg/larva/day of rotten vegetable waste (Pakcoy) and were replicated 3 times. Variables observed during the study were the growth rate, consumption capability, level of waste reduction (waste reduction index, WRI), consumption efficiency (efficiency of conversion of digested-feed, ECD), the weight of harvested biomass, and protein content of larvae, pupae, and adults. The results showed that there was no significant correlation between the weight of harvested biomass and the amount of substrate provided to larvae (one-way ANOVA, P > 0.05). The increasing amount of substrate reduced the efficiency of waste reduction and consumption (one-way ANOVA, P < 0.05). This study also showed that the possible upper limit of consumption capability of larvae was 400 mg/larva/day. On the other hand, the increasing amount of substrate increased the protein content of biomass of each developmental stage.

Abstract

The whitefly, Bemisia tabaci (Gennadius) and the aphid, Myzus persicae (Sulzer) are important pests in tomato and chilli pepper. These pests directly attack and as a viral vector can decrease the production of tomato and chili pepper. Menochilus sexmaculatus (Fabricius) and Micraspis lineata (Thunberg) are predator beetles of B. tabaci and M. persicae. This study aimed to know the potential predation of M. sexmaculatus and M. lineata as a predator of B. tabaci and M. persicae. Completely randomized factorial design using 2 factors consist of type and density of prey with 3 replicates used in this study. The potency of predatory coccinellidae as predator of B. tabaci and M. persicae was evaluated in 2 observations, i.e. predation and functional response assay. Based on logistic regression analysis, both of M. sexmaculatus and M. lineata showed characteristic of type I functional, this means that the higher density of prey, the ability and predation rate of M. sexmaculatus and M. lineata were also increased. The predator M. sexmaculatus and M. lineata were more effective to control M. persicae than B. tabaci.  M. sexmaculatus was the effective predator to control adult of M. persicae.

Abstract

A previous report has indicated that in many regions of Indonesia, populations of Musca domestica have shown very high resistance to permethrin and low resistance to imidacloprid. In this study, the resistance status to permethrin and imidacloprid was updated using a topical application and feeding bioassay. Six housefly strains originated from six highly populated cities in Indonesia, namely Serang (SRG), Jakarta (JKT), Bandung (BDG), Semarang (SMG), Yogyakarta (JOG), and Surabaya (SBY). A seventh strain (Danish Pest Infestation Laboratory) served as the control. Each strain was tested for resistance to the two insecticides. The rate of development of resistance to the two insecticides was measured over ten generations. The results indicated that all field strains showed very high resistance to permethrin. The highest resistance level recorded was in the SRG strain (RR50 = 2880), and the lowest was in the JKT strain (RR50 = 520). Repeated application of permethrin over ten generations increased the resistance level by about 2.7–32.73-fold as compared to the level of their respective parental populations. On the other hand, most strains showed low to moderate resistance to imidacloprid, in which the SRG strain had the highest resistance level (RR50 = 15.5) and the SBY strain had the lowest (RR50 = 2.0). Repeated application of imidacloprid over ten generations increased the resistance level by about 3.25–17.41-fold. The findings, which is the second report of housefly resistance in Indonesia since 2016, provide a crucial foundation for developing appropriate housefly integrated pest management strategies in highly populated areas in Indonesia.

Abstract

Kanzawa spider mite, Tetranychus kanzawai Kishida (Tetranychidae) is one of the most important pest mite in Indonesia. This mite is known as the pest of many crops, including cassava. Neoseiulus longispinosus Evans (Phytoseiidae) is a predatory mite commonly found on plant infested by kanzawa spider mite. This predatory mite has high potential to be developed as biological control agent of T. kanzawai. The aim of this research is to elucidate the effective density and release time of N. longispinosus to control T. kanzawai on cassava. The research was conducted in the greenhouse, using cassava of Mentega cultivar. T. kanzawai were introduced into the cassava plants two weeks after planting, with density 5 female adults/plants. N. longispinosus were introduced 1, 2, and 3 weeks after T. kanzawai introduction with predator:prey ratio of 0:5, 1:5, 2:5, dan 3:5, respectively. Population of T. kanzawai and N. longispinosus, and also plant damage were observed at 6 weeks after planting. N. longispinosus could suppress T. kanzawai population and the highest suppression occurred at the interaction between 3:5 ratio and the release time at one week after T. kanzawai infestation. There was no significant effect of N. longispinosus release at various release ratio and time on attack intensity of T. kanzawai.
