Hymenoptera is one of the four largest insect orders in the world, one of which is its role as a natural enemy (parasitoids, predators). Land conversion can affect the diversity and composition of the parasitoid Hymenoptera and its ecological role. This study aims to examine the effect of land use types on the diversity and composition of hymenopterans parasitoid in Jambi. The study was conducted on various types of land use in the Harapan Forest landscape and Bukit Duabelas National Park (TNBD), Jambi Province including forests, rubber forests, oil palm plantations, and rubber plantations. Insect sampling was conducted from March to September 2013, using fogging techniques. A total of 14,258 hymenopteran parasitoid individuals consisting of 30 families were obtained from all study sites. Encyrtidae, Braconidae, Aphelinidae, Eulophidae, Scelionidae, Ceraphronidae, and Platigasteridae families are found in high abundance. Oil palm land use types are found to have different parasitoid compositions compared to other land use types, while forest and rubber forest land use types have high species composition. The results of this study indicate that the type of land use affects the diversity and composition of hymenopteran parasitoid species.

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.

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.

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.

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.
