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.

The use of intensive and excessive insecticides on cabbage cultivations causes pest resistance, pest resurgence, environmental pollution, chemical residues, as well as decreasing the population of natural enemies and soil arthropods. Various pest control techniques have been developed to reduce the pest population, two of them are intercropping systems as part of cultural technique strategy and insecticide application. The aim of this research was to study the effect of three cabbage (Brassica oleracea) cultivation patterns and different criteria in insecticide application against soil arthropod diversity including the natural enemy population. The research was designed using split-plot experimental design. The three cultivation patterns consisted of intercropping cabbage with tomato, cabbage, and Ageratum sp. as refugia plant, and monoculture cabbage. Three criteria in insecticide application were economic threshold-based application, calendar system, and without insecticide application. In general, the results showed that cabbage monoculture cultivation and insecticide applications resulted in the lowest soil arthropod population among other treatments. Treatments of cabbage and Ageratum sp. and without insecticide application could increase the diversity of soil arthropods.

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.

Sexava, the long-horned grasshopper, is an important pest of the coconut palm that destroys leaves and fruits. Study on analysis of damage to leaves and fruits of coconut palms due to being attacked by Sexava was aimed to determine the mechanism of the damage. Visual in situ observations were carried out in Salibabu Island, Talaud Islands Regency, North Sulawesi Province, while histological and chemical analyses of attacked young fruits and observation of symptoms of the secondary disease were carried out in the laboratory. The results showed that the process of damage to coconut-palm leaves and fruits due to bitten by the Sexava occurs mechanically. Phytotoxic symptoms due to bites of the long-horned grasshopper and symptoms of the secondary disease were not observed. Fruit tissue with a thickness of several millimeters appears to dry out and die while the tissue near the wound appears normal. Reduced sugar levels, cellulose, and lignin, between healthy fruit tissues (1.22%, 2.72%, 5.66%) and those attacked (1.22%, 2.85%, 4.84%) were relatively the same. The attacked young-fruits will fall out while attacked fruits on bunches more than 3 months old still keep to grow and develop until ripe.

Rhopalosiphum rufiabdominale (Sasaki) and Tetraneura nigriabdominalis (Sasaki) are aphid species found in the roots of rice plants. Information about the host range and biology of R. rufiabdominale is relatively known than T. nigriabdominalis. This study aims to determine the biology and demographic statistics of R. rufiabdominale and T. nigriabdominalis in the roots of rice plants. The aphids obtained from lowland rice roots in Leuwiliang, Bogor Regency were maintained and reared in Ciherang variety rice roots in the laboratory. Each individual of the 1st instar aphid nymph in the same cohort was infested into the roots of rice in 60 plastic containers for biological observations and statistical demographic variable data collection. Survivorship (lx), fecundity (mx), and the average number of nymphs born by adult every day at age (x) are used to calculate demographic statistical parameters. The results showed that the two species of the aphids have 4 nymph instars. Life cycle and longevity of R. rufiabdominale were 4.98 days and 15.94 days with fecundity of 67.44 respectively, whereas the life cycle and longevity of T. nigriabdominalis were 5.25 days and 18.11 days with fecundity of 11.11 respectively. R. rufiabdominale aphids have an intrinsic growth rate (r) of 0.46 days and a doubling time (DT) of 1.50 days, whereas T. nigriabdominalis has an intrinsic growth rate of 0.14 days and a doubling time of 4.99 days. The results of this study indicate that although the life cycle lengths of the two species are almost the same, the population of R. rufiabdominale develops 3.5 times faster than T. nigriabdominalis and therefore R. rufiabdominale has the potential to become an more important pest in rice plants.

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.

Diversity of spider groups have received less research attention and there are limited published references for spiders from Peninsular Malaysia. The current survey was conducted to locate and identify foliage-dwelling spiders (Arachnida, Araneae) at five different sites in Peninsular Malaysia. Spider specimens were collected using manual search and sweep-netting between September 2012 and November 2012. A total of 92 morpho-species from 65 genera that belong to 15 families have been successfully recorded and identified. The greatest proportion of specimens captured (40%) were Foliage-runners (Clubionidae, Miturgidae, Oxyopidae, Pisauridae, Salticidae, Scytodidae, Thomisidae), followed by orb-weavers (Araniedae, Nephilidae, Tetragnathidae, Uloboridae) (36.5%), space-weavers (Pholcidae, Psechridae Theridiidae) (21.5%) and ground-dwellers (Sparassidae) (2.0%). Cluster analysis has revealed that the same habitat types share a more similar diversity composition compared to different habitat types, which indicates that spider assemblage composition was partly co-dependent on vegetation structure. However, no significant difference in spider assemblage composition was found between all the five sites which follows that these diurnal group of spiders are actually adaptable to various habitat types.

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.

Parasitoid Anagyrus lopezi (De Santis) (Hymenoptera: Encyrtidae) was introduced from Thailand into Indonesia in early 2014 to control the invasive cassava mealybug, Phenacoccus manihoti Matile-Ferrero (Hemiptera: Pseudococcidae). Research was conducted in laboratory with the objectives to determine effect of honey on adult longevity, to study fecundity, progeny production, and sex ratio, and to evaluate effect of increased host density to parasitization. Studies were carried out by exposing 3rd instar nymphs of mealybug to parasitoids. Effect of honey on adult longevity was done in the absence of hosts. Fecundity was measured by the number of mummies formed. Results showed that adult females lived for 3.7 days, while males lived for 3.2 days when only provided water. Adult longevity increased significantly when honey was provided. Parasitoids with access to 50% honey lived almost six to nine fold longer than those provided water. Over its adult life, A. lopezi parasitized 96–287 mealybugs with an average of 203.7 or 34.6% of hosts were parasitized, and 24.86% were killed through host feeding. Development from egg to adult emergence required 17.97 and 17.67 days for males and females respectively. The average number of offspring produced per female was 88.8 individuals, of which 56.9% were females. The number of hosts parasitized at densities varying from 2–100 cassava mealybugs corresponded to a type III functional response.
