Bogor and its surrounding area is known as one of the region in West Java that has high diversity of horticultural plants that may have an affect on fruit fly diversity. Research on fruit fly diversity is not merely provide information on the species richness of fruit flys but also provide information on its distribution and dispersion. The aim of this research was to investigate the diversity and distribution of fruit flies species and their hosts in Bogor and its surrounding area. Fruit flies were collected from 119 sampling areas in Bogor Cianjur, Bekasi and Depok. Fruit flies were sampled using two methods, i.e. host rearing and trapping. Traps were modified from Lynfield traps and combined with two different attractants, i.e. metil eugenol (ME) and Cue lure (CL). We found 18 species of fruit flies collected from traps and 24 host plants. The result showed that distribution, diversity and abundance of fruit flies was influenced by the diversity of host plants.

A study on the effect of abaticidal ovitrap on Aedes aegypti egg findings was carried out in Cipinang Muara, East Jakarta from October 1997 until January 1998. Twenty five houses were designed as treatment objects. Ovitrap were sit indoor and outdoor in each house. Seventy five houses were used as buffer. People in this area were trained on how to set up and to manage their ovitrap. Control area in the same "Rukun Warga (RW)" was selected and treated with the same way. The result has shown that egg number from the treated area has significantly reduced and less than the egg number in the control area. The mean the number of eggs found in the first year was 20.8 eggs, while in the second year was 38.8 eggs. The average ovitrap index (01) in the first year was 38.8 'Yo, while in the second year was 49.4 %. Abate did not affect the activity of oviposition and the number oflaid eggs.

On early development of intensive cotton program, insect pests were considered as an important aspect in cotton cultivation, so that it needed to be scheduled sprays. The frequency of sprays was 7 times used 12L of chemical insecticides per hectare per season. Development of cotton IPM was emphasized on non-chemical control methods through optimally utilize natural enemies of the cotton main pests (Amrasca biguttulla (Ishida)Helicoverpa armigera (Hübner)). Conservation of parasitoids and predators by providing the environment that support their population development is an act of supporting the natural enemies as an effective biotic mortality factor of the insect pests. The conservation could be done by improving the plant matter and cultivation techniques that include the use of resistant variety to leafhopper, intercropping cotton with secondary food plants, mulch utilization, using action threshold that considered the presence of natural enemies, and application of botanical insecticides, if needed. Conservation of parasitoids and predators in cotton IPM could control the insect pests without any insecticide spray in obtaining the production of cotton seed. As such, the use of IPM method would increase farmers’ income.

The existence of Ephemeroptera, Plecoptera, and Trichoptera (EPT) in a body of water can be used as indicators of the quality of the waters. The aim of this study were 1) to know the diversity of EPT insects in Jangkok River, Lombok, West Nusa Tenggara, 2) determine the water quality of Jangkok River based on family biotic index (FBI), and 3) to know the effect of physical, chemical, and biological of environment parameters on the presence of EPT insects. Sampling was conducted in Jangkok River, Lombok, West Nusa Tenggara, in the dry season of July 2016. EPT groups insects were taken using water nets and eckman grab in 22 sampling points that was randomly determined in systematic random sampling. Data of physical, chemical, and biology of waters were also taken in these sampling points. Water quality is determined by the score of FBI, and the multiple correlation analysis to determine the relationship between physical and chemical parameters with the presence of EPT. Biological parameter was analyzed descriptively. The influence of biological parameter was determined by descriptive analysis. The study found 902 individuals of EPT belonging to 12 family and 12 genera. In the upstream we found 788 individuals (12 family and 12 genus), in the middlestream found 114 individuals (10 family and 10 genus), while in the downstream the EPT was absent. From the seven physical and chemical parameters of waters tested, only water temperature has significant correlation with the presence of EPT. The differences of water temperature in these area were caused by the covering and heterogeneity of the vegetation in the river side in each area. FBI score for upstream was 3.6 which indicates that the quality of the waters are very good. In the middlestream, the FBI score was 4.6, and it was categorized as good. In the downstream, results of the FBI get infinite value that entered the category as very bad.

A parasitoid, Anagyrus lopezi (De Santis) (Hymenoptera: Encyrtidae) was introduced from Thailand into Indonesia in early 2014 to control the cassava mealybug Phenacoccus manihoti Matile-Ferrero (Hemiptera: Pseudococcidae). To determine its potential uses and effect on non-target species, behavioural observation of the parasitoids were made on four species of mealybugs, i.e. P. manihoti, Paracoccus marginatus Williams-Granara de Willink, Pseudococcus jackbeardsleyi Gimpel-Miller, and Ferrisia virgata Cockerell (Hemiptera: Pseudococcidae). For that purposes, a set of tests were conducted which includes host susceptability, preference, and suitability. Tests were conducted by exposing a female parasitoid to 3rd instar nymphs of each mealybug species in a petri dish. For susceptability test, parasitoid A. lopezi encounterend P. manihoti more often (13.70 ± 7.18 visits per 30 minutes) as compared to P. marginatus (985 ± 10.24), P. jackbeardsleyi (6.60 ± 3.62), and F. virgata (5.75 ± 4.09). So did ovipositor probing occurred more on P. manihoti (8.20 ± 5.68 probes per 30 minutes) than on P. marginatus (0.70 ± 1.84), P. jackbeardsleyi (0.35 ± 0.68), and F. virgata (0.10 ± 0.45). For preference test, host encounter and ovipositor probing by the parasitoid were more common on P. manihoti as opposed to other mealybug species. Out of four mealybug species tested, P. manihoti was the only suitable host for parasitoid development, with the number of progenies emerged 7.40 ± 2.17 individuals per 3 female parasitoids exposed in 24 hour. Host specifity exhibited by parasitoid A. lopezi may prevent adverse effect to other mealybug species inhabiting cassava fields.

T. armigera is one of the potential egg parasitoids. The aim of this research was to study the effects of low temperatures ( 9ºC and 15ºC) on the fitness of T. armigera. The design of the experiments is a factorial design with two factors (temperature and age of parasitoid), with 10 replicates. Fitness were measured based on the survival, fertility, size, sex ratio, lifespan and fecundity. Result showed that the emergence of T. armigera was postponed by 2-5 days under low temperatures. Temperatures had a more significant effect than age of parasitoid. The postponement of adult emergence is very useful in regard to field application schedules. Percentage of adults emergence, sex ratio, egg productivity, fecundity tended to decrease under low temperatures, the length of female adult wings varied in each treatment and it tended to be shorter in 9ºC, while the width of female adult heads was almost similar in all treatment except in untreated control. These characters are very important in determining the fitness of the parasitoid in the field.

Plant damages caused by leafhopper, Empoasca terminalis Distant (Homoptera: Cicadellidae) on soybean were first encountered in 2007 in Makassar, South Sulawesi. The insect has been constantly associated with soybean crops in the province ever since. The purposes of the present study were to (i) evaluate potential yield loss attributable to the leafhopper in an experimental set up, (ii) seasonal abundance of E. terminalis, and (iii) distribution of E. terminalis in all major soybean-producing areas in the province. Potential yield loss due to the leafhopper was assessed in a field experiment using two large plots. One of the plots was kept leafhopper-free by weekly insecticide sprays; and the other plot was left unsprayed to allow leafhopper infestation to occur. Adult abundance was weekly monitored using a sweep net throughout the season. Nymph abundance was determined by direct count on the plant leaves. Leafhopper distribution was assessed through surveys conducted in all major soybean-producing areas in South Sulawesi, from 2009–2013. The results of the study showed that E. terminalis caused an average yield loss of 26% on susceptible crops without insecticide use. First leafhopper infestation in all planting seasons occurred two weeks after the plant emergence. Rainfall negatively correlated with the leafhopper abundance. The leafhopper existed in all major soybean production areas in the province. Therefore, our results confirmed the status of E. terminalis as an important soybean pest in the region. In addition, crops planted early in the dry season could escape from heavy leafhopper infestation.

Cnaphalocrosis medinalis (Guenee) is a potential rice pest. The research was conducted at Subang district, used randomized block design. The big plot with 80 m x 100 m is planed by Ciherang rice variety. The big plot is divided to two plots with each size 40 m x 100 m. The first plot controlled by fipronil insecticides, but another one do not controlled us untreated plots. The untreated plot is divided to 160 small plots with size 5 m x 5 m. Observation on 30 hills per plot of randomize three plots every weeks. The result of this research show that abundance of larvae and pupae of leap folder on Ciherang variety was bimodel with two peaks. These curve indicated that leaf folder development reach two generation in one season. The relationship curve between rice plant old and leaf damage was linear curve with correlated value was 87%, but relationship curve with correlated value was 95%. The leaf folder more develop on the vegetative phase than on generative phase. The existent of larvae parasitoid, Elasmus sp is very late and abundance began of 70 days rice old with 14.8 % larvae parasitism. In the nearest harvest the larvae parasitism up to 94.4%. Amount of parasitoid is very high to reach 225 parasitoid per larvae on 70 days rice old. Analog rice growth on dry season 2002 a leaf damage level was 5-50% and effect to yield losses was 833.3 kg/ha grain dry harvested or loosing income was Rp. 1,085,550.

The objective of this research was to study the influence of host deprivation on the oviposition and physiological condition of Snellenius manilae Ashmead. The research was conducted at Laboratory of Bioecology of Parasitoid and Predator, Department of Plant Protection, Faculty of Agriculture, IPB. Ten parasitoids of the same age and cohort were used in this experiment. Deprivation of hosts were done for 1, 2, 3, 4, 5, 6 and 7 days at the beginning and toward the end of their life. All hosts were replaced every 24 hours. Result indicated that host deprivation affects the reproductive capacity of Snellenius manilae. Even though parasitoids were able to lay eggs even when they were deprived of hosts for seven consecutive days, the overall results of host deprivation experiment showed that the length and timing of deprivation period can affect reproductive capacity. Deprivation of hosts tends to increase the parasitism rate and the numbers of eggs laid upon their first encounter of hosts after the treatment. The difference is more pronounced on treatements that allowed parasitism to occur before the deprivation treatment. However, the overall results suggests that deprivation overall decrease the reproductive capacity of the parasitoid. The longevity of deprived individuals was also lengthened. Parasitoids that were given host before deprivation treatments tend to produced more eggs than those were not. These results showed that deprivation of hosts in the field may affect the effectiveness of parasitoids and the success of biological control.

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.
