Pollination within syconium (figs) of the fig trees (Ficus spp.) depends on female fig wasps that belong to Family Agaonidae (Order Hymenoptera); on the other hand, the female wasps can only lay eggs inside the fig flowers in which the offspring later develop. Several species of non-pollinating wasps are also known to develop within the figs. A research to investigate the fig wasps community (pollinator and non-pollinator) and their impact on the figs has been conducted on fig tree species of Ficus racemosa L. in Aceh Province. Fig fruits of F. racemosa were sampled when they were on receptive stage (B-phase) and when the figs were almost mature (D-phase) on the same trees. The young figs were dissected to observe the pollinating wasps (foundresses), while the mature figs were incubated until the new generation of fig wasps emerged from the figs. The wasps then were identified and counted. Observations on B-phase figs showed that the pollinating wasps of F. racemosa was Ceratosolen fuscicep (Mayr) (Hymenoptera: Agaonidae) which entered the fig through ostiole. The fig wasps community that emerged from D-phase figs consisted of pollinating and non-pollinating fig wasps, Platyneura fusca dan P. agraensis (Hymenoptera: Agaonidaed) were the competitors of pollinating wasps in taking the ovules for their development, while Apocrypta sp. (Hymenoptera: Pteromalidae) was a parasitoid of the pollinator. However, in this research there was no evident that the presence of these non-pollinating wasps significantlyt affect the number of pollinating wasps and seeds of F. racemosa.

Flies are well known as vector that has an important role in transferring pathogen microbes to broilers. Various tropical plants, as well as Cymbopogon spp. possess a large potential in controlling the activities of this flies. This research was aimed to determine the effect of citronella oils extracted from Cymbopogon nardus L on Musca domestica L. (Diptera: Muscidae) activities in ration surface and also to study the effect of COE in ration on broiler performances. Three treatment levels of EMC were 0%, 0.25%, and 0.5% and added in broilers ration experimental. The research was designed by using randomized experimental design. The parameters measured were: proportion of physical contact frequency (PCF), feed consumption, and body weight gain. The results showed that the treatment levels of COE of C. nardus significantly influenced (F2,48 = 38,456, P=0,000) PCF of M. domestica, while the levels of COE were significantly influencing (F2,36 = 51,178, P = 0,000) the feed consumption and body weight gain of broilers (F2,36 = 81,969, P=0,000). This research revealed that the levels of COE of C. nardus were able to decrease PCF value of M. domestica in ration while the treatments increased feed consumption and body gain values of broilers. We concluded that EMC of C. nardus L up to 0.5% can function as bio-repellent to the M. domestica activities on broiler ration and cause a positive effect to the consumption and to the body gains of chickens broilers.

Collembola are essentials for soil health, because of their are as decomposers of organic material. However, Collembola are still not widely know in Indonesia. Information about Collembola is very limited, especially in oil palm plantations, so it is very interesting to study. The research aims to study the abundance and diversity of Collembola and also examines the influence of environmental factors (rainfall and humidity) toward Collembola population. The study was conducted in smallholder oilpalm plantations in four villages namely Bungku, Pompa Air, Sungkai, and Singkawang at Bajubang Jambi. The observations were conducted in November 2013 until April 2014. Soil sampling is done by using a rectangular blade measuring 16 cm x 16 cm which is inserted into the ground as deep as 5 cm. Soil samples were taken on four plots located in four villages. At each location a single plot of 50 m x 50 m is made. Soil sampling was performed on the weedly zone area and inactive pathway area for 6 months, 3 samples on the open ground and 3 samples on the compost line randomly. The results showed that Collembola obtained from all observed areas were 3 orders, 7 families, and 21 genus with a total abundance of 21,951 individuals. Collembola abundance found on the weedly zone area numbered 9,960 individuals consisted of 3 orders, 6 families, and 17 genus. While at inactive pathway area numbered 11,991 individuals consisted of 3 orders, 7 families, 16 genus. Among the three orders found Entomobryomorpha has the highest abundance of 19,999 individuals, both on the weedly zone area and inactive pathway area. From the results of research suspected that high and low levels of abundance and diversity influenced by fertilization, drought, and herbicides. Fertilization of the organic matter can increase abundance, were while drought and herbicide can reduce abundance of Collembola.

Reclamation has an important role in the recovery of mined land ecosystems and is expected to restore the diversity of insects such as Coleoptera. Reclamation process can change Coleoptera diversity and formed communities new of functional groups. The objective of this research was to study the diversity, functional role, and composition of the Coleoptera in the reclamation area. This ecological research was conducted in reclamation area of PT. Berau Coal in Binungan, Berau District, East Kalimantan. Several ages of reclamation area were selected for observation i.e. 2, 4, 6, 8 and 10 years and also natural forest as comparison. Insects were sampled using pitfall trap and malaise trap in a 100-meter transects for each age revegetation. The results showed that there is no difference in the diversity of Coleoptera between age of reclamation. Age of reclamation tend to affect the composition species and functional role of Coleoptera. Abundance of predatory Coleoptera show differences in different reclamation ages, while the abundance of other functional group (herbivor detritivor and mycophagus) does not seen to be influenced by age of reclamation. Nevertheless, there is an increasing trend of Coleoptera abundance of herbivores and detritivor group with increasing age reclamation.

The egg parasitoid, Scelio pembertoni Timberlake (Hymenoptera: Scelionidae), is an obligate endoparasitoid of Acrididae. One of the hosts of S. pembertoni is the eggs of Oxya japonica (Thunberg)(Orthoptera: Acrididae). The objectives of this research were to determine the development stage of S. pembertoni, longevity and fecundity, and the preference of S. pembertoni against different host age. S. pembertoni were collected from O. japonica eggs taken from cultivated and wild taro fields in Bogor area. The life cycle of S. pembertoni consisted of egg stage, first and second instar larval stage, pre-pupal and pupal stage, and adult stage. The first instar larva was teleaform and transparent white. The second instar larva was hymenopteriform and transparent white. The immature stage of S. pembertoni lasted within 27–33 days under laboratory condition, and was consisted of egg development period, first instar stage, second instar stage, pre-pupal stage, and pupal stage was 1.8, 4.95, 4.25, 5.40, and 12.85, respectively. Longevity of the adult females was 7–17 days, and longevity of the male adults was 3–11 days. The average fecundity of the females was 29.53 eggs. The sex ratio (male to female) of S. pembertoni during observation in the laboratory was 1 : 3.19. The parasitisation level and the number of offsprings produced by S. pembertoni was higher on younger host eggs than the older ones.

Insects hold important role in pollination of many crops. However, studies on pollination in Indonesia could be considered rare. This study focussed on obtaining the basic information of wild pollinators and the effect Trigona (Tetragonula) laeviceps Smith innundation release to the production and quality of pumpkin (C. maxima) in traditional farming system. Observations were carried out from 07:00 to 15:00 during flowering period for 3 weeks. Sampling area was divided into three plots : open pollination + T. laeviceps (OPT), open pollination (OP), and hand pollination (HP). Pollination was assessed by three main parameters, which were visitation pattern, plant reproductive success, and fruit quality. Visitation pattern was assessed by measuring frequency and duration of pollinator visits, the plant reproductive success by fruit set and number of seed produced; while fruit quality by diameter, weight, and number of fruit produced/plant. We recorded different visitation pattern in which wild pollinator preferred to visit flowers in the morning while T. laeviceps preferred to visit from noon to afternoon. This pattern could be relate to difference in thermal tolerance among pollinators. There were significant differences among fruit set produced in OPT (80%), OP (65%), and HP (38.3%) (F2,35 = 19,907, P = 0,000). Number of seeds and fruit quality produced in OPT and OP much higher than HP while number of fruits produced in OPT significantly higher that OP and HP. Low pollination success in HP showed pollination process in pumpkin highly depend on pollination time. Thus, pollination by bees in pumpkin hard to be replace by human and variation of visit provided by T. laeviceps produce positive effect to pumpkin.
