Helopeltis antonii Signort (Heteroptera: Miridae) has long been reported to attack cacao and other host plants in Java. A recently published literature review refuted this idea and offered morphological evidence suggesting that this attacker is actually H. bradyi Waterhouse. However, through the present, local reports still identify attacks as coming from H. antonii. To confirm which of these two species is implicated in cacao damage, we conducted an examination of the external morphology, genitalia and the biology of Helopeltis sampled from infested cacao plants in Yogyakarta. 42 females and 9 males, sampled from 3 different locations, were observed to be morphologically similar to H. bradyi, especially with regard to the pale band on the base of all femora, the knife-shaped male lobal sclerite, and the presence of a ‘Y’ shaped junction on the posteriorly fused female genital chamber. The duration of the life stages (in days) of the laboratory-reared insects were: 7−11 (eggs), 12−19 (nymphs), 9−44 (female) and 16−54 (male) d, measurements which fall within the ranges of the parameters usually reported locally for H. antonii, with the exception of male adult life stages which are longer than the aforementioned reports. Morphological changes were observed during all stages of development, including within adult stages. In female adults specifically, external morphology and genital development proceeded continuously until the insects reached the full-grown condition, characterized by stable color, and fully sclerotized genital chamber. Our preliminary study of the morphology and development of lab-reared insects descended from individuals infesting cacao fields, indicated the presence of H. bradyi instead of H. antonii in Yogyakarta, and therefore stipulated a need to review the existence of the latter in Indonesia.

Non target impact of classical biological control of exotic species in the ecosystem. Classical biological control has been hailed as a successful control method of many exotic species of pests. However, recently this method of control has been questioned due to several cases of non target impact. Non target impact can occur two ways, i.e. direct non target impact when there is a host shift of the bioagents (e.g. changes in preferences), and the indirect non target impact which can occur through, among others, food web subsides that will change the overall interactions of many species within an ecosystem. The aim of this paper is to understand the interactions between introduced exotic agents (e.g. insects) toward local diversity, e.g. what are the implications of the interactions toward local biodiversity? Are there non target and indirect impacts of these introductions in Indonesia? The discussions covers the concept of biological control and conservation issues that should be taken into consideration, particularly in the context of insect conservation and impacts of classical biological control on island diversity.

The control of dengue hemorrhagic fever (DHF) it is important to control the vector, i.e. Aedes aegypti (Linnaeus) and Ae. albopictus (Skuse). Usually, controls of these vectors are done using chemical insecticides. Research on mosquito resistance has been done, but the impact of mosquitoes that survive after synthetic (chemical) insecticides application has not been studied. The aim of this research was to analyze the differences of fecundity, fertility and vitality rate of mosquitoes that were exposed to natural insecticides i.e with burned breadnut flowers and mosquito coils containing transflutrin and d-aletrin. Mosquito samples were taken from field eggs which were exposed with synthetic and natural insecticides. Mosquitoes that remainder alive after 24 hours exposure were mated and each group were put in 2 cages, each repetition were repeated 3 times. The mosquito eggs were observed until adult mosquitoes die. Then, the fecundity, fertility and vitality rate were compared. Based on our analysis, there were no differences on fecundity rate, between control and mosquitoes that were exposed to natural insecticides, but there were significant differences between the control and the synthetic insecticides. Natural insecticides do not increase the rate of fecundity but synthetic insecticides may increase the rate of fecundity and number of mosquitoes and causes the mosquito lifespan longer than the control and natural insecticide treatment.

Local isolates of entomopathogenic nematodes are symbiotically associated with bacteria of the genus Xenorhabdus or Photorhabdus. Symbiont bacteria isolated from local isolates of entomopathogenic nematode (Pujon, Cemoro Lawang and X. nematophilus) were identical with Xenorhabdus spp and isolate of Ngadas was identical with Photorhabdus luminescens. Some isolates, such as Xenorhabdus (isolate of Pujon) and P. luminescens (isolate of Ngadas) has a high virulence when the bacteria was injected into insect haemocoel. High virulence was indicated by Xenorhabdus nematophilus when it was applied orally.

The continous presence of dengue virus infection presents a serious health problem in many tropical areas of the world because of the severe and often fatal disease in children. Dengue viruses are transmitted to human through the biting of infected mosquitoes, especially Aedes aegypti and Aedes albopictus. This paper reported the nocturnal of biting activity of Ae. aegypti and Ae. albopictus in several areas of Indonesia. Natural population of Aedes was collected by bare leg collection and resting collection from 18:00 to 06:00 out door and indoor. The biting activities of Ae. aegypti and Ae. albopictus occurred throughout the night from 18:00 to 05:50 out door and indoor in Cikarawang, Babakan, and Cibanteng Kabupaten Bogor (2004); Cangkurawuk Darmaga Bogor (2005, 2007); Pramuka island, Pari island, Kepulauan Seribu (2008); Gunung Bugis, Gunung Karang, Gunung Utara Balikpapan (2009); and Kayangan, Lombok Utara (2009). These results showed that the biting activities of Ae. aegypti dan Ae. albopictus did not only occur diurnally but also nocturnally.

Lombok Island (West Nusa Tenggara) is one of the major papaya producer in Indonesia. In the last five years, papaya production in West Nusa Tenggara has decrease continuosly. Pest mites is one the constraint found in papaya production in Indonesia. At the present there is no data available related with mites on papaya in Lombok island. Thus, the aim of the research is to determine the identity of pest mites on papaya in Lombok Island. Mites collected from 50 different location of 5 districts in Lombok Island. From each location, 3 plant were sampled for observation, two leaves from each plants were collected. Identification of mites were conducted by using morphological characters such as stigma, gnathosoma, and idiosoma. The results revealed twelve spesies of pest mites of papaya in Lombok island, they were Aculops pelekassi Keifer, Calacarus carinatus Keifer, Brevipalpus californicus Banks, B. obovatus Dannadieu, B. phoenicis Geijskes, Tenuipalpus pasificus Baker, Eutetranychus africanus Tucker, Panonychus citri McGregor, Tetranychus fijiensis Hirst , T. kanzawai Kishida, T. piercei McGregor, and Tarsonemus bilobatus Suski.

Plant extracts have been known to cause physiological and biochemical interferences against insect, such as feeding inhibitor, food assimilation, and changes on activity of cytochrome b5 and cytochrome P450. This study was carried out to examine the effect of the extracts mixture of Tephrosia vogeliiand : Piper aduncum (1 : 5) on the physiology of Crocidolomia pavonana (F.) as well as extract of P. aduncum on biochemical of C. pavonana. The study showed that larvae of C. pavonana was experiencing a feeding inhibition until 94.82% after treated with extracts mixture on concentration 0.06% or equivalent to LC95. However, larvae treated with extracts mixture on LC25 and LC50 only experienced a relative growth disorders as a result of intrinsic toxicity of extracts mixture which enters into the body of insects. Insect adaptation to toxic plant compounds indicated by an increase in the digestibility of larvae approximately 11.11%. Furthermore, detoxification mechanism by larvae against active compounds of P. aduncum occured and shown by an increase of oxidative enzyme activity of cytochrome b5 and cytochrome P450, in in vivo and in vitro compared to control. This study provides an information about mode of action of extracts mixture of T. vogelii and P. aduncum (1 : 5) on larvae of C. pavonana and detoxification mechanism by larvae due to extract of P. aduncum

Study Hyperparasitoid Existing Affected to Adul Parasitoid Behavior on Aphid, Aphis gossypii (Hemiptera: Aphididae). In general, hyperparasitoid is needed for establishing food and chain webs, but in contrary, it could become a limiting factor in existing biological control program. An observation to aim positive impact of hyperparasitoid existence has been carried out. Chili plant, Capsicum annuum, Aphis gossypii, Trioxys sinensis parasitoid and Aphidencyrtus sp. were used in this observation. Results showed that hyperparasitoid existence assisted parasitoid distribution. Parasitoids were placed with hyperparasitoids enhanced parasitoid distribution or dispersion two times farther compare to without hyperparasitoids. It was concluded that dispersal behaviour of hyperparasitoid adult was a parasitoid adult’s response to avoid its suppression by the hyperparasitoid and also increase parasitoid’s searching ability.

Sanurus sp., Acrocercops sp. and Helopeltis sp. are important pests of cashews in Nusa Tenggara Barat. Pesticide usage to control these pests has so far not been successful, and thus the usage of natural enemy as an alternative control methods should be developed. Spider represents one of the natural enemies which are found in cashew plantation. The aims of the research is to study spider population and its predatory ability in cashew plantation. The study has been conducted in an area of cashew plantation at Dusun Jugil, Desa Sambik Bangkol, Lombok Utara. Spider predation was directly observed for 78 days, starting from May to August 2009. Edgar formula was used to measure spider predation per day. The study found 19 species of spider consisting from eight families. The abundance of Neoscona theisi is higher than Tetragnatha maxillosa, but the proportion of N. theisi with prey is less than T. maxillosa. This phenomenon indicates that spider’s abundance, does not directly show its potential as natural enemy in that habitat. N. nautica consumed at least 3.84 preys per day, but not all of its prey represents the pest of cashew. N. theisi consumed 1.67 preys per day and all of its prey represents pests of cashew. This study show that the amount of prey which can be consumed by spider per day does not directly show the potential of spiders as natural enemey of cashew pest.
