Lac insect (Laccifer lacca Kerr) (Homoptera: Kerriidae) is an insect species that attack various plant species and produce lac as a by-product. The insects produce compact and thick natural resin and attached to the branch commonly called shellac. Branch lac is a natural resin from the secretion process of insects named L. lacca in the form of a thick-layered lac that covering the branches of the host plant. Parasitoids and predators attack lac insect has a direct impact on the decrease in shellac productivity. The aim of the research is to determine the dynamics of parasitoid populations on lac insect, the diversity of parasitoids and predators attacking lac insect, identification parasitoids and predators that attack to lac insect, measuring parasitization level in BKPH Kabuaran and Taman, KPH Probolinggo, Perum Perhutani Unit II - East Java. Samples branch lac of BKPH Kabuaran and Taman each of 200 lac branch was collected. The dominant families of parasitoids found are Aphelinidae, Encyrtidae, and Eulophidae. Predators found to consist of Family Lathridiidae (Coleoptera), Cosmopterigidae and Noctuidae (Lepidoptera), Nabidae (Hemiptera), and Chrysopidae (Neuroptera). The cumulative amount of parasitoids in the field is more high (5.900 individuals) than in warehouses (5.263 individuals). The highest increase of individual parasitoids in the field and warehouses occurred at the observation day 7th to 17th. The parasitization level of lac insect in the field and warehouse was high i.e., 93% and 96% respectively. It can be concluded that lac insect from both the field and werehouse are alike parasitized.

Eucalyptus spp. are commonly cultivated in the forest industry sector as the raw material for the pulp and paper industry. One of the problems in Eucalyptus plantations is leaf galls caused by insects. Leaf galls can cause leaf damage and inhibit plant growth. The objective of this study was to identify insects associated with leaf galls on eucalyptus plants. Leaves with gall symptoms were collected in the Tele sector located between Humbang Hasundutan and Samosir Regencies, North Sumatra Province. Identification was based on morphological characters of the antenna, dorsal mesosoma, fore wings, and hind legs. Results showed that there were seven insect species associated with leaf galls on Eucalyptus, i.e. Ophelimus eucalypti (Gahan) (Eulophidae) pest gall on eucalyptus leaf, Eurytoma sp. Illiger (Eurytomidae), Aprostocetus sp. Westwood, Quadrastichus mendeli Kim & La Salle, Chrysonotomyia germanica (Erdös), and Closterocerus chamaeleon (Girault) (Eulophidae) acts as a parasitoid and Diplesiostigma bisetosum Boucek (Tetracampidae).

Papaya mealybug, Paracoccus marginatus Williams & Granara de Willink (Hemiptera: Pseudococcidae), is an invasive pest that was detected for the first time in Indonesia in 2008. One of the common natural enemies is the predatory beetle Cryptolaemus montrouzieri Mulsant (Coleoptera: Coccinellidae). The research was conducted with the objectives to determine the biology, life table parameters, and predation of C. montrouzieri on P. marginatus. Observation of biological and life table parameters and predation was conducted by introducing the predators into Petri dishes containing mealybugs. Eggs of C. montrouzieri hatched in 4.35 days. Mean developmental periods for 1st, 2nd, 3rd, and 4th instar larvae were 4.23; 4.21; 5.84; 5.93 days, respectively. The mean pre-pupal and pupal periods were 1.95 and 7.55 days, respectively. The longevity of male adults was 51.34 days, while that of females was 83.39 days. The number of eggs laid by a single female averaged 198.49. The net reproductive rate (Ro) was 117.11 individu/female/generation, intrinsic rate of increase (rm) was 0.073 individu/female/day, mean generation time (T) was 64.776 days, doubling time (Dt) was 9.426 days, and finite rate of increase (Î») was 1.076 per day. The 4th instar larvae of C. montrouzieri was the most voracious with numbers of P. marginatus eggs, 1st, 2nd, 3rd instar nymphs or adults consumed were 188.0; 53.4; 44.0; 26.8; or 15.6; respectively. Manly's preference index suggested that larvae, as well as adults of C. montrouzieri, preferred eggs and 1st instar nymphs of P. marginatus over other mealybug stages. Our study indicates the high potential of C. montrouzieri in the biological control of P. marginatus.

Pseudagrion pruinosum (Burmeister) is a common damselfly that is widely distributed in Southeast Asia. However, information related to the oviposition behavior and habitat is still limited. This study was aimed to determine the behavior of P. pruinosum when laying eggs and characterized the oviposition habitat. This research used focal sampling method to observe oviposition behavior and measure habitat parameters on egg-laying location. Results showed, there was mate guarding when P. pruinosum females lay eggs. The male forms a tandem formation (contact mate guarding), then released the female and keep a guarding behavior around the female (noncontact mate guarding). Eggs were placed by the female on plant tissue with the technique of positioning the body to remain on the surface and then submerged. There is no tendency of P. pruinosum behavior towards one type or technique. Based on the results of principal component analysis, 75.8% of habitat components can be described for egg-laying habitat. Air temperature, pH, light intensity, and heterogeneity of vegetation positively correlated with the occurrence of egg-laying while TDS, humidity, water depth, and water temperature were negatively correlated. The results of this study concluded that the characteristics of egg-laying techniques included, i.e contact and noncontact mate guarding by the males and females putting eggs on the surface then submerged into water.

Sparganobasis subcruciata Marshall is a species of weevil occurring in Papua and eastern parts of Indonesia, which had been begun found to causes damage to oil palm in the Boven Digoel district. The research was carried out to investigate the symptoms of S. subcruciata attack and it’s damage level in one of oil palm plantation in Boven Digoel. The result shows that larvae of this weevil bore into the stem, particularly the lower part, giving rise to symptoms which are similar to symptoms of Ganoderma disease, specifically the occurrence of more than three leaves in the spear failing to open, hanging down and drying out and the ultimate death of the palm. The weevil has been detected in Boven Digoel, Papua, where significant numbers of oil palms appeared to be dead or dying in each of the plantation visited by us. We consider that this weevil constitutes a major threat to oil palm plantations in Papua and that it may in the future, if it is not already the case, be a threat to plantations in Eastern Indonesia. Early detection of the presence of the weevil is difficult and requires research, as do methods of control, which we suggest should focus on the development and use of pheromones.

Nilaparvata lugens Stí¥l (brown planthopper [BPH]) is one of the major pests that cause a decline in rice productions. BPH population abundance in rice crops is affected by weather factors. An early indication of the BPH population abundance in the crop can be seen from the number of captured BPH on light traps. This study aims to analyze the influence of weather factors on the population dynamics of BPH, caught by the light traps. The method analysis used is correlation analysis and linear regression analysis. When multicollinearity problems occur among the weather factors, the influence was analyzed using principal component regression method. The result showed that rainfall, minimum humidity, and rainy days have a strong correlation to the BPH population dynamics. Based on subset tests between these three factors, two best factors were chosen, namely the rainy days and minimum humidity. The regression equation between rainy days and minimum humidity against the BPH population clearly describes the relationship of BPH population that increases along with the increase in the number of rainy days accompanied by the fluctuation of minimum humidity in the environment.
