Connection between Zea mays L., Ostrinia furnacalis (Lep.:Pyralidae) and Beauveria bassiana Vuill. The entomopatogen fungus, Beauveria bassiana (Balsamo), is obtained in the tissue of corn plant through submersion of seed in cinidia 1010/ml. Tissue observation showed that hifa B. bassiana appears when the plant attain the age of three weeks and when it reaches six weeks B bassiana appears in all sample plants. Hifa obtained in parenchyma tissue passively without causing illness the mother plant. The appearance of B. bassiana is remained until the 12th weeks of plant. Bio test of plan which contain the endofit of B. bassiana showed the percentage of tested insect mortality is 64%. The observation showed that the corn plant can still produce the toxin of beauverisin.

In 2010 the pilot project of PJR program (routine larvae monitoring) was firstly implemented in Pedurungan village. The program was expected to increase community practice in mosquito eradication program (PSN-plus). The study was aimed to describe the difference of PSN-plus practice in pilot- and nonpilot- PJR villages. This was a comparative survey with cross sectional design. The study subject was household in pilot- and nonpilot-PJR villages which, consisted of 90 respondents each. The selection of study subject used proportional random sampling technique. To measure the of PSN-plus practice, questionnaire and observation sheet were used. Statistical analysis was performed with Chi-Square test. The result showed that PSN-plus practice in pilot village was better than nonpilot one. The statistical test proved the difference of bathtub drain (p value=0.006), closed water containers (p value=0.002), demolished used stuffs (p value=0.001), and hanging clothes habit (p value=0.0001).

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.

Subterranean termites Macrotermes gilvus (Hagen) (Blattodea: Termitidae) belongs to the subfamily Macrotermitinae they are distributed widely in Southeast Asia such as Indonesia, Malaysia, Singapore, Myanmar, Philippine, Vietnam, and Thailand. Many studies on these termites have been conducted, but the study of relatedness termites from different locations are barely done. The objective of this study was analyze the relatedness between subterranean termites M. gilvus in IPB Dramaga Campus and Yanlappa Nature Reserve, Jasinga-Bogor. The termite relatedness was analyzed with agonistic behavioral approach and molecularly, technique using mitochondrial COI gene. Termites from both locations showed identical molecular relatedness, however behavioral analysis show that they belong from different parental lineages. Agonistic assessment showed that individuals from different habitat showed aggressive behaviour, whereas those that originated from the same nest do not show any aggression. Molecular detection however have failed to show.

The objective of the research was to study sex ratio and oviposition sequence of egg parasitoid Trichogramma chilotraeae in relation with host density under laboratory condition. Parasitoid response with respect to oviposition sequence was examined by exposing five different host (egg) densities: 3, 6, 12, 24 and 48 on female parasitoids T. chilotraeae. Results showed that in general, female parasitoid laid its female progeny at the beginning of oviposition sequence. Host density was found to have a strong effect on sex ratio. Sex ratio increase with increasing of host number.

Field and laboratory studies were conducted on potatoes in pangalengan during April until October 2001, with the objectives to determine the daily activity pattern of the predatory fly Coenosia humilis Meigen (Diptera: Muscidae), to study the behavior of predator as well as level predation, and to evaluate effects of two cultural practices on population of flies. Our research revealed. that C. humilis were more active during morning and afternoon. Predatory flies attacked by capturing the flying preys, and then sucked preys body content. The preys were generally small insects. About 60% of the preys were found to be agromyzed files, Liriomyza huidobrensis (Blanchard) (Diptera: Agromyzidae). In laboratory each predator consumed 23.5 leafminer flies per day. Insecticide application significantly suppressed the predator and at the same time promoted the leafminer population.

The brown planthopper, Nilaparvata lugens Stål. is a destructive and widespread insect pest throughout the rice areas in Indonesia. Rice plant resistance is an effective method in controlling N. lugens. However, the resistance sources and how their mechanism for imparting induced resistance against brown planthopper remains to be nderstood. This research was aimed to identify plant hair and protein banding patterns, as a genetic expression, of resistant and susceptible varieties. Identification of the variation of number of plant hair were carried out by using binocular microscope, while the protein banding patterns was detected by separation on SDS-Page. Co-variants analysis was adopted to identify the groups of resistant cultivars based on protein banding patterns. The results showed that plant hair on resistant rice cultivars are different with susceptible cultivars (resistance to Pelita I/1). The plant hair on resistant cultivars are larger/longer, more abudant and grew tighter than on susceptible cultivar. However the number of plant hair have no correlation with resistance level. In the absence of brown plant hopper infestation, the expression of protein total of resistant and susceptible cultivars are not clearly separated. Pelita I/1 varieties showed a similar banding pattern to IR 26 (biotype 1), IR 42 (resistance to biotype 2) and IR IR 74 (resistance to biotype 3), but the four cultivars are not similar to the resistant cultivar IR 36 varieties (resistance to biotype 2). Our research showed that both plant hair and protein banding patterns can not be used to identify the plant resistance.

Tingkat pemangsaan Neoseiulus longispinosus Evans (Acari : Phytoseiidae) terhadap Tetranychus urticae Koch dan Tetranychus kanzawai Kishida (Acari: Tetranychidae) serta perilaku kanibalismenya Edwin Iswella; Pudjianto Pudjianto; Sugeng Santoso

Tetranychus urticae Koch and Tetranycus kanzawai Kishida are important pests of various crops of economically importance in Indonesia. Acaricide are commonly used to control these mites. One of the alternative control methods is the use of phytoseiid predatory mites. Most of the phytoseiid mites that are used as biological control agents are exotic mites. For that reasons, it is necessary to study indegenous predatory mites that has the potential to be developed as biological control, such as N. longispinosus. The objective of this study was to determine the predation capacities of N. longispinosus on two red spider mites of T. urticae and T. kanzawai and the effect of predator densities to predator cannibalistic behavior. N. longispinosus were supplied with eggs and adults of T. urticae and T. kanzawai to determine the predation capacities. N. longispinosus were also supplied low number of T. kanzawai eggs as the prey at several predator densities to see its cannibalistic behavior. The results showed that the number of eggs of T. urticae dan T. kanzawai consumed by deutonymphs and adult females of N. longispinosus was higher than the adult female of T. urticae dan T. kanzawai. The number of eggs of T. urticae dan T. kanzawai consumed by adult female N. longispinosus was higher than by the deutonymphs. The number of eggs laid by adult females of N. longispinosus when feed on eggs of T. urticae and T. kanzawai was higher than those feed on adult female. Deutonymph and female adult stage of N. longispinosus showed cannibalistic behavior at several predator densities in low number of prey.

The effectiveness of this parasitoid was influenced by its population structure in the field. However, because this parasitoid has a tiny size, it was difficult to know the population structure of this parasitoid. This problem can be overcome by using molecular characteristic i.e. molecular markers. Based on RAPD-PCR analysis from 4 selected primers on 19 DNA samples from 3 different locations it was fond, that Gunung Bunder II population was divided into sub-population and so did Cugenang population, which is indicated by their small Fst and Nm index. The Fst and Nm index for Gunung Bunder II population was 0,39 and 0,77, while 0,51 and 0,47 for Cugenang population. If we calculated the Fst and Nm for all samples together, we found that this parasitoid has a random mating pattern, which is also shown by the dendrogram. The dendrogram indicate that each sub- opulation from one location was not grouped in one cluster but distributed in every cluster.

The objective of this research is to study the effectiveness of T. remus as biocontrol agent for S. exigua. The study was conducted by releasing a set of T. remus females on potted onion plants that have been attacked by S. exigua. Three different parasitism level was artificially created by releasing different numbers of females: low rate parasitism (release of 4 adult females), moderate parasitism (7 females) and high parasitism level (11 females). The result of this study showed that T. remus is effective to control S. exigua population. Up to 48.2% of S. exigua. population was able to be suppressed by the high parasitism level. Rate of parasitisation was more when more adult female T. remus was released. Release of 11 adult female of T. remus can increase the population level of the parasitoid up to 24.1 times than the initial population. This express that T. remus is a mortality factor which can regulate the population of S. exigua. However, the succesfull parasitisation of T. remus is also dependent on environmental factors such as temperature, humidity, food, and host suitability.
