The Elevated and Activity of Acetilcholinesterase Enzyme on Aedes aegypti Selected by Malathion. The aim of this research was to study the effect of selection by malathion on the activity level Acetilcholinesterase enzyme on Aedes aegypti mosquitoes. Selection of Aedes aegypti larval by mean of malathion have been conducted for 20 generations. During the selection process time has been increased of concentration applied and exposure. For generation 0-5 (F0-F5), a concentration of 25 µl/l (24 ppm) was used to expose the larvae to malathion for five minutes. In generation 6-10 (F6-F10) the concentration has increased to 50 µl/l (48 ppm); in F11-F15 the concentration used was 100 µl/l (96 ppm) whereas in F16-F20 200µl/l (192 ppm) was used. Mosquito generations that would be regarded as representative and reference groups were F0, F5, F10, F15 and F20. The LC50 of F0, F5, F10, F15 and F20 was 0,025; 0,032; 0,042; 0,062 and 0,071 ppm respectively. Increases LT50 values was also observed in Aedes aegypti selected by malathion. The LT50 of F0, F5, F10, F15 and F20 generations was 7,9; 11,3; 18; 30,6 and 33,1 minutes respectively. The low levels of malathion resistance could be conferred by the elevated of α-esterase. The values of the α-esterase in F0, F5, F10, F15 and F20 were 0,155; 0,174; 0,203; 0,209 and 0,215 µmol/min/mg protein respectively. The acetilcholinesterase activities were also raised in F0, F5, F10, F15 and F20, the value of acetilcholinesterase activities were 20,35; 20,26; 23,14; 23,18 and 24,9%.

The condition of agroecosystem may affect the diversity and effectiveness of parasitoid communities as natural enemies of insect pests. Agricultural intensification such as monoculture cultivation as well as application of insecticide could also cause declining to parasitoid diversity and ineffective performance of parasitoids in agricultural field. The objective of this research was to study trophic interaction between pests and parasitoids in different field of vegetable crops and to investigate the factors that determining those interactions as well as its implication on parasitoid effectiveness. Vegetable crop fields were grouped into three different categories i.e. based on the pattern of cultivation, diversity of vegetable crops around the field and age of plant. On each crop field, insects were sampled using 50 m of transect by collecting eggs, larvae and pupae of pests. In total, 15 species of pests and 15 species of parasitoids were recorded from eight species of vegetable crops. Based on the analysis, trophic interaction between pests and parasitoids were affected by cultivation system, condition of crop field (species diversity of crops in its surrounding) and age of vegetable plants. Although it was not significance, the effectiveness of parasitoids according to their parasitism level, tend to higher in trophic interaction that determined from crop field with organic systems and with diverse of crop plants.

Staphylinid beetle (Coleoptera) is characterized by short elytra with orange, brown, or black body color. The objective of this research was to analyse diversity of staphylinid beetles in paddy and sweet potato fields and distribution of the species in sweet potato field. Collections of beetle were done by using road sampling method in two types of agricultural fields. Distribution of beetle population were observed in the plots (1 m x 1 m) placed systematically. Seven species of staphylinids were found in this research. Five species (Paederus fuscipes Curtis, Stenus sp., Astenus sp., Hypostenus sp., and Cryptobium abdominale Motsch.) were found in paddy fields. We also found five species of staphylinid beetles (P. fuscipes, Medon sp., Stenus sp., Hypostenus prahoeensis Benick, and Philonthus sp.) in sweet potato fileds. In paddy and sweet potato fileds were dominated by P. fuscipes. Diversity of staphylinid in paddy and sweet potato fields were low. In sweet potato fields, P. fuscipes showed highest important value index (115.98%), followed by Stenus sp. (69.35%), and H. prahoeensis (5.65%). and Population distribution of P. fuscipes, Medon sp., Stenus sp., dan Philonthus sp. were uniform, while H. prahoeensis was clump.

Currently, most cockroach control in urban environment relies on bait application. Aversion of some commercial bait by cockroach cause failure to control cockroach problems. Developing local bait can improve this situation. This research was aimed to find proper combination of some cockroach diet to be formulated in effective bait. Research was conducted in Department of Plant Protection, Bogor Agricultural University, since November 2007-March 2008. Combination of peanut butter, chicken egg, and strawberry jam seem to be a candidate of effective bait for local cockroach.

Host plant preference amongst several fruit species was studied for two fruit fly species i.e. Bactrocera carambolae (Drew & Hancock) and Bactrocera dorsalis (Drew & Hancock), which both belong to B. dorsalis species complex. Both fruit fly species are known to be polyphagous and cause significant economic losses as pests of fruit crops. The aim of this research was to assess the host range of these major pests in Indonesia. The research was conducted at the Entomology Laboratory and Insect Specimen Collection Laboratory, Indonesian Center for Agriculture Biotechnology and Genetic Resource Research and Development, Bogor, West Java, Indonesia from June 2011 to March 2012. Comparative host preference for both species was studied with regard to malaya varieties of star fruit (Averrhoa carambolae), manalagi varieties of mango (Mangifera indica), guava aka water apple (Psidium guajava), citra water guava (Eugenia aquae), jamaica bol guava (Eugenia malaccenensis), and california papaya (Carica papaya). Our results suggest the strongest preference for malaya star fruit by B. carambolae followed by manalagi mango; and for california papaya followed by manalagi mango by B. dorsalis. The study also found that welahan variety star fruit is least preferred by both species of fruit fly.

Several methods can be used to control pest infestation, especially by the use of biological agents that do not contaminate environment. Virus as a biological agent has already been used to control army worm on some plants. Some benefits can be obtained when biological agents are used to control insect infestation. The objectives of these studies were to obtain: a method to produce MsNPV formulation from rice army worm; an effective and efficient method to pack and store MsNPV formulation as biological agent of rice army worm and an efficient application method of MsNPV formulation to control rice army worm. These studies were conducted at laboratory and green house in Bogor and rice field in Indramayu and Sukabumi, West Java during the planting season of 2005. The experiment consisted of several parts: production of suspension and MsNPV formulation from the larvae of ricearmy worm, packing and period storing of MsNPV formulation, observe the effect of MsNPV formulation on rice army worm in the rice fileds. Results from these studies show that the number of larvae used will effect production of suspension and formulation of MsNPV. The number of larvae used would increase the production of suspension and the value of formulation will also increase. While method of packing, period of time and location of storing showed that time period of 1; 2; and 3 months at different colour of plastic also location of storing refrigerator vs room temperature did not effect on mortality of larvae rice armyworm.

Insect diversity and vegetation structure are two aspects that affect the reproduction of insectivorous birds. The objective of this study was to investigate the characteristics of the original habitat Lanius schach in Tanjungsari of particularly the type, composition of vegetation, and preference to insect sprey. Observation of vegetation and insects were conduct using a combination methods of the track and checkered line on the transect along the 10 km (ten observation points). Insect and tree species were counted on plot (20 m x 20 m), shrub (10 m x 10 m), bush (5 m x 5 m), and grass (2 m x 2 m). Vegetation analysis was used to calculate the structure and composition of vegetation, whereas Shannon diversity index was used for insect diversity. Prey test was conducted to determine the preferences of insectivore birds on insects. The composition of the vegetation species consists of 7 grasses, 20 bushes, 5 shrubs and 18 trees. The dominant species of vegetation based on highest important value index was Tectona grandis, Ipomoea sp., I. cylindrica, and Panicum brevifolium respectively. The highest diversity index of vegetation group were bush (2.430), tree (1.696), grass (1,680), and shrubs (1.364), respectively. Insect diversity index was 2.572 and grasshoppers (Orthoptera) was the most preferred prey by L. schach. Overall, the habitat of insectivore birds L. schach are dominated by T. grandis, and has high diversity of bush.

The surveys of larval parasitiod Plutella xylostella, which have been done in cabbage plantations area in Batu and Poncokusumo, Malang east Java, found other larval parasitoid biside the commonly larval parasitiod Diagdema semiclausum. The parasitoid was Teratichus howardi (Hyminoptera: Eulophidae). The percentage of parasitism was dependent of the altitude of cabbage plantation and developmental stage of crop. The percent of parasitism could reach 82% when parasitized larvae sampled in cabbage plant and the crop stage. Parasitism was also higher at the medium lowland rather than it was that the upland. T. howardi is a gregrarious larval-pupa endoparasitoid. The life cycle of T. howardi was 14-16 days. The longevity of male and female was influenced by the availability of hosts or the change of mating. The longevity of mated female which was offered some host is 14-21 days, but the longevity of mated female without hosts was 38-56 days. The mated male parasitoid lived from 1 to 4 days, but they lived 12-16 days when they were not mated. One female could lay some cluster of egg varied from 35-60 eggs cluster or from 142 to 235 eggs during the lifespan. One eggs cluster consist of ±4 eggs. The parasitoid laid one or two clusters of egg per host. Parasitoid laid eggs soon after mating at day one from eclosion until day 19th. Four to 28 Parasitoids could emerge from one host. One parasitoid was able to parasitize 17-30 larvae of P. xylostella.

One of the important pests on chilli plants is Thrips parvispinus Karny (Thysanoptera: Thripidae). The presence of the pest is detected ranging from lowlands to highlands. This study was aimed to find out the morphological diversity of T. parvispinus at three different altitudes which include Cirebon (< 30 m asl), Bogor (300 - 400 m asl), and Cianjur (> 1200 m asl). At each level of altitude, it was collected 60 female adults of the thrips and then they were preserved into microscope preparations using Hoyer medium. The observed morphological characters of T. parvispinus were the length of body, the width of head, the width of thorax, the length of wing, and the color of body. The difference in morphological characters of the thrips in all three levels of altitude were analyzed using analysis of variance and Duncan's multiple range test. The correlation between altitude and body color was analyzed using chi- square test. Results showed that the body length, thoracic width, and wing length of the highland thrips were longer than those of the mid and lowland thrips. The three morphological characters showed significant differences between the mid and lowlands and the highlands, except for the character of head width. Changes in the color of the head, thorax, and abdomen were correlated to the level of the altitude.

Tetragonula laeviceps (Smith) is one of the most common species of stingless bees in Indonesia. However, only few publications available on the flight activity rhythms of the species. Research was conducted with the objectives to determine flight activity of T. laeviceps in relation to daily times and various weather elements. Three colonies of T. laeviceps were observed hourly for 5 minutes beginning at 06.00 a.m. until 06.00 p.m. Number of bees entering with pollen or resin, as well as exiting with waste were counted. Flight activity was significantly different (P < 0.001) among times of day. The preferential times (acrophases) of flight activities occurred at afternoon (11 a.m. to 12 a.m.). Number of entrance and exit flights positively correlated (moderate) with temperature and light intensity, while negatively correlated (moderate) with relative humidity.
