One of the recognized and safe quarantine treatments for consumers is the use of gamma-ray irradiation [60Co] at a recommended dose requested by the destination country or international agency. The purpose of this study was to test the effectiveness of a generic dose of gamma ray irradiation for sterilizing mango pulp weevil Sternochetus frigidus (Fabricius) on mangoes cv kuini (Mangifera odorata). A total of 300 kg pulp-weevil-infested mango fruits was collected from West Sumatra and Lampung. First experiment was conducted on April to irradiate fruits collected from West Sumatera and second experiment was on May to irradiate fruits collected from Lampung. In each treatment, a box containing 6-8 M. odorata fruits was irradiated with gamma-ray at doses of 50, 100, 150, 200, 300, 400 Gy with three replications. The treatment of gamma-ray irradiation could reduce feeding activity, normal life of insect, egg production and increase mortality of adults. The results of the first and second experiments showed that gamma ray irradiation was able to influence the development of pupae and adults. There were differences in the normal development of adults in the two experiments. The number of normal development of adults on first experiment was higher than on the second experiment. The irradiated pupae at dose of 100 Gy successfully develop to be adults but the adults are unable to produce eggs. Adults irradiated at 150 Gy are still able to lay eggs with the average of 6 eggs (first experiment) and 2,3 larvae (experiment II), 150 Gy average 6 eggs and do not hatch. Doses at 200 Gy no eggs were produced.

Insects’ oviposition behavior on alternate host plants is very helpful to understand the interaction between host plants and insects, the dynamics of insect populations, and the effectiveness of alternate host plants as refugia in managing insect resistance. The oviposition preference of Ostrinia furnacalis on maize (Zea mays L), king grass (Panicum maximum Jacq.), and cogon grass (Imperata cylindrica (L.) was studied through no-choice test, two-choice test, and three-choice test. The oviposition preferences hierarchy of O. furnacalis on maize, king grass, and cogon grass wass sequentially maize > king grass > cogon grass when the tested plants were at 21 DAP (days after planting). However, the hierarchy pattern may change depending on host plants phenology. The 35-day-old king grass was more preferred by O. furnacalis (proportion of eggs = 0.692; OPI = 37.57) than maize (proportion of eggs = 0.301; OPI = -38.780) and cogon grass (proportion of eggs = 0.174; OPI = -65.183) for oviposition. These findings indicated that king grass was a potential alternate host for O. furnacalis to survive and could serve as refugia in IRM strategy. However, it needs further research in the field to ensure the potential of king grass as refugia for O. furnacalis.

Jambi province is one of the regions in Indonesia that has tropical rainforests with different landscape characteristics in each region. Tropical rainforests contain the highest biodiversity in the world and as a habitat for various types of flora and fauna, including elaterid beetles. Elaterid beetles have an important role as ecological bioindicators. The aim of this research was to study the diversity and species composition of elaterid beetle in two different landscape types. Insect sampling was carried out in Jambi Province on two tropical rainforest landscape, i.e. Bukit Duabelas National Park (TNBD) and Harapan Rainforest. Elaterid beetles were collected by canopy fogging method in the morning. Each landscape consists of four core plots and each core plot consist of three as subplot, total subplots observed in both landscape were 24 subplots. A total of 2069 individuals of elaterid beetles were collected, belonging to 6 subfamilies, 23 genera, and 59 morphospecies. The abundance of elaterid beetles was higher in Harapan Rainforest, while species richness was higher in TNBD landscape. Species dominant in two landscape consist to subfamily Agrypninae, belonging to genera Adelocera with morphospecies Adelocera sp.01. The result of this research showed that landscape differences influencing the composition and abundance of elaterid beetles, but it does not influence in species richness of elaterid beetles.

Spodoptera exigua (Hübner) are nocturnal insects and one of the important pests of shallot. The activities of nocturnal insects are influenced by the moonlight. The aim of this research is to analyze the effect of moonlight on oviposition behaviour: number of egg patches, number of eggs per patches and egg gpatches distribution pattern of S. exigua. The research was done on three shallot field at Brebes Regency, Central Java during the new, half and full moon. The sampling included observing the number of egg groups, the number of eggs per egg group, and egg groups distribution pattern of S. exigua on each observation plot. The egg groups distribution pattern of S. exigua based on Morisita index. The result of this research showed that the number of egg groups and the number of eggs per egg group always increased from the new, half, and full moon. In general, the egg groups distribution pattern of S. exigua were clustered on three moonlight conditions. High intensity of moonlight (full moon) was be able to increase the number of egg groups and the number of eggs per egg groups of S. exigua, its potentially cause more attacks.

Stored product insect can cause consumer rejection and economic loss due to quality concerns and phytosanitary regulation. Insect traps have been regularly used as a control method, however its effectiveness on controlling stored copra meal insect pests is not yet known.This study was carried out to compare the effectiveness of three types of insect traps for detection of insect pests of copra meal.The three types of insect traps were pitfall trap, probe trap, and ultraviolet (UV) light trap (blacklight and LED-light emiting diodes). Research was conducted at Laboratory of Entomology SEAMEO BIOTROP, Bogor and two storage facilities of copra meal in North Sulawesi. Laboratory experiment was conducted using completely randomized design with two factors and four replications. The first factor was the types of insect traps (pitfall trap, probe trap, and probe trap with UV LED) and the second factor was insect species (Lasioderma serricorne (Herbst) and Tribolium castaneum (Fabricius)). The experiment at storage facilities was conducted with nested block design where the insect species trapped were nested in the insect traps. The result of laboratory experiment showed that the probe trap captured more insects (30.4%) significantly higher than pitfall trap (17.1%), however there was no significant difference of number of insects trapped in probe trap with and without UV LED. In addition the probe trap captured more T. castaneum and Tenebroides mauritanicus than other type of insects trap, but probe trap with UV LED was more effective to detect L. serricorne and Necrobia rufipes (Fabricius) in the stored copra meal.

Hypsiphyla sp. include the Order Lepidoptera, Family Pyralidae. These insects is one of the important pests on mahogany plants (Swietenia macrophylla King.). This pest has been found to attack S. macrophylla plants in North Sulawesi, especially in the area of mahogany plant centers namely North Minahasa Regency and Tomohon City. The aim of the study was to determine the CO1 gen profile of mahogany shoots borer (Hypsipyla sp.) on mahogany plant (Swietenia macrophylla) in Minahasa Regency and Tomohon City, North Sulawersi Province. The method used is descriptive method, consists of extraction or purification of total double strands DNA (dsDNA), amplification of CO1 gene by PCR method, visualization of PCR results with atomatic electrophoresis qiagen, and sequencing. The sequenced data that is the construction of the phylogeny tree are described according to clusters which give the morphometric character of each sample. The results of the analysis of genetic differences between Hypsipyla sp. origin of North Minahasa and Tomohon namely 3.8%–4.4%. Hypsipyla sp. origin of North Minahasa and Tomohon with H. grandella namely 9.0%–9.3%. Based on the results of this analysis it can be seen that the kinship of Hypsipyla sp. in North Minahasa Regency and Tomohon City it is closer to H. robusta than H. grandella. Results of cluster analysis of Hypsipyla sp. in North Minahasa Regency and Tomohon City, North Sulawesi Province compared to H. robusta and H. grandella in the Gen Bank mapped in the phylogeny tree construction indicate that Hypsipyla sp. in North Mihasa Regency and Tomohon City, North Sulawesi Province already exists or forms a separate clade with H. robusta and H. grandella clades in Bank Gen.
