Influence of host stage on oviposition, development, and sex ratio of Anagyrus lopezi (De Santis) (Hymenoptera: Encyrtidae),a parasitoid of the cassava mealybug, Phenacoccus manihoti Matile-Ferrero (Hemiptera: Pseudococcidae). The parasitoidAnagyrus lopezi (De Santis) (Hymenoptera: Encyrtidae) was introduced from Thailand into Indonesia in early 2014 to controlthe invasive cassava mealybug, Phenacoccus manihoti Matile-Ferrero (Hemiptera: Pseudococcidae). Because of the need toproduce large numbers of high-quality females, research was conducted in the laboratory to determine host stage preferencefor A. lopezi on different instars of P. manihoti. Individual female wasps were exposed to first, second, third instar nymphs,and pre-reproductive adult mealybugs. In the no-choice test, the frequency of parasitized hosts and the number of eggs laidper host was significantly higher in second and third instar nymphs as well as adult mealybugs compared to first instarnymphs. In the two-choice test, third instars nymphs and adult mealybugs were the most preferred host for oviposition.Immature development of parasitoids was faster and the ratio of female to male parasitoids was higher following ovipositionin second and third instar nymphs and pre-reproductive adult hosts, compared to the first instar nymphs. Our findingsindicate that the use of pre-reproductive adults as hosts in a mass-rearing program would be the most productive and fastestway to produce A. lopezi populations with a female-biased sex ratio. Field release of parasitoids should be conducted whenthe hostâ€™s third instar nymph is the most abundant because the period during which preferred and suitable host stages areavailable would be the longest.

Virus tungro disease is a serious problem to rice crop in a certain area of rice production in Indonesia. The disease is caused by a combined infection of Rice Tungro Bacilliform Virus (RTBV) and Rice Tungro Spherical Virus (RTSV). Both viruses were reported to infect ratoon rice plants, weeds, and wild rice. The study was conducted to detect RTBV and RTSV on some weeds. Weed samples were collected from rice fields in West Java, Bali, West Nusa Tenggara, Papua, and West Sumatera. The detection of RTBV and RTSV were carried out using Polymerase Chain Reaction (PCR) and Reverse Transcription (RT) â€“ PCR, employing coat protein gene specific primers. RTBV specific DNA fragment of ~1400 bp size was successfully amplified from various weed species including: F. miliacea, C. iria, M. vaginalis, L. adscendens, S. zeylanica, D. sanguinalis, and E. crusgalli. RTSV specific DNA fragment of ~787 bp size was successfully amplified from weed species of F. miliacea, L. octovalvis, and D. sanguinalis. RTBV or RTSV specific DNA fragment was not amplified from L. flava and P. distichum. Weed samples infected by both viruses did not show any tungro symptom. Virus detection based on molecular technique was able to determine the status of weed whether it is as an alternate host of viruses. Weeds sanitation prior to rice planting, therefore, should be considered as an integral part of virus disease management.

During 2008 crop season, an outbreak of severe yellow mosaic disease on yard long bean (Vigna unguiculata subsp. Sesquipedalis) occurred in several farmers’ fields in West Java. Yard long bean var. Parade inoculated manually with extracts from symptomatic leaves showed the symptoms indicating the presence of virus. Symptomatic leaf samples tested positive in enzyme linked immunosorbent assay (ELISA) with antibodies to group specific Potyvirus and Cucumber mosaic virus (CMV). Total RNA derived from symptomatic leaves was subjected to reverse transcription-polymerase chain reaction (RT-PCR) using primers specific to the cylindrical inclusion (CI) protein of potyviruses and CMV coat protein (CP) specific primers. Pair wise comparison of sequences obtained from cloned RT-PCR products with corresponding nucleotide sequences in the GenBank confirmed the presence of Bean common mosaic virus strain Blackeye (BCMV-BlC) and CMV in the symptomatic beans. Sequences of BCMV and CMV isolates from the beans showed maximum nucleotide sequence identities (92-97%) and (90%), respectively with BCMV-BIC and CMV isolates from Taiwan. Each virus isolate also clustered closely with corresponding isolates from Taiwan in a phylogenetic analyses. These results provide first evidence of the occurrence of multiple infection of BCMV-BIC and CMV in the yard long been from Bogor, West Java. Key words: yard long bean, BCMV-BIC, CMV, Bogor Indonesia

Liriomyza sativae is a polyphagous agromyzid leafminer and it has invaded large part of world, i.e Hemiptarsenus varicornis, Gronotoma micromorpha, and Opius dissitus. This research were conducted to investigate progeny, immature development period, longevity of female parasitoids of L. sativae, and to study female parasitoid behaviour in host finding. Host finding behaviour was observed by examining their visit frequency to the leaves that mined by leafminer larvae and healthy leaves. Results showed that H. varicornis produced more progenies (10.70 + 2.58 progenies/female), but not significantly different (P < 0.05) from progenies produced by G. micromorpha (9.90 + 3.81 progenies/female) and O. dissitus (9.60 + 3.31 progenies/female). The immature development period of G. micromorpha (25.65 + 0.38 days) was found to be longer than H. varicornis (16.14 Ã‚Â± 1.20 days) and O. dissitus (14.03 + 0.22 days). Significant different (P = 0.1014) of adult longevity was not found among H. varicornis (9.22 + 2.48 days), G. micromorpha (7.25 + 1.34 days), and O. dissitus (8.74 + 2.18 days). Our analyses also indicated that G. micromorpha and O. dissitus found their hosts based on the larvae mining, however, H. varicornis performed it randomly. Based on the number of progeny and longevity of adult female, all parasitoids tested may have a potential as biological control agents of leafminer, L. sativae. Key words: fecundity, longevity, behavior, Hemiptarsenus, Gronotoma, Opius, Liriomyza sativae

Anastatus dasyni Ferr wasp (Hymenoptera: Eupelmidae) is one of the parasitoids attacking eggs of the pepper berry sucking bug, Dasynus piperis China (Hemiptera: Coreidae). Study was conducted in the laboratory to determine immature development, adult longevity, fecundity, sex ratio, oviposition preference, and number of host parasitized. The result showed that immature development time from egg up to adult was 15.57 + 0.09 days, mean fecundity was 99.45 + 5.60 eggs, and sex ratio (% of females) was 67.28 + 0.56%. If provided with honey 10% and host eggs, females lived for 37.7 + 2.78 days and males 6.30 + 0.56 days. Host eggs aged one and two days were more preferred by A. dasyni for oviposition. Mean number of hosts parasitized by this wasp aged less than one day was much lower as compared to the older one. Key words: pepper, pepper berry sucking bug, Dasynus piperis, parasitoid, Anastatus dasyni

Cycad aulacaspis scale (Aulacaspis yasumatsui Takagi (Hemiptera: Diaspididae)) is native to Thailand and Vietnam. Since the early 1990s it has been spreading around the world due to the trade in cycad plants for ornamental use. Infestation by this scale can kill cycads in only a few months. Its accidental introduction to Florida endangered the ornamental cycad-growing industry; and in Guam and Taiwan, endemic cycads (Cycas micronesica and C. taitungensis, respectively) are currently threatened with extinction by cycad aulacaspis scale. In November 2011, an introduced scale was discovered damaging cycads in the Bogor Botanic Garden. Samples from Bogor were taken for identification of the scale, and the material was kept for some time to rear out any insect parasitoids that were present. Both the scale insects and parasitoids were prepared on microscope slides and studied microscopically for authoritative identification. The scale was confirmed as A. yasumatsui. The parasitoid Arrhenophagus chionaspidis Aurivillius (Hymenoptera: Encyrtidae) and the hyperparasitoid Signiphora bifasciata Ashmead (Hymenoptera: Signiphoridae) were identified from the samples. Unless immediate remedial measures are taken, several endemic species of cycad in Indonesia may be endangered by infestation by cycad aulacaspis scale.

The brown planthopper Nilaparvata lugens (Stal.) causes hopperburn in the rice field. The wing macropterous adults of this insect have capability for long distance flight. We aimed to analyze the genetic structure of six N. lugens populations in Java inferred from the combined COI-COII mitochondrial and ten loci of microsatellites markers. This study found low levels of nucleotides and high levels of haplotype diversity of the planthopper. The demographic test might indicate the genetic bottleneck history of N. lugens population in Java. The genetic diversity analyzed by using microsatellite markers also showed high levels of heterozygosity (Ho>He) that indicated an isolated-breaking effect in the six populations in Java. Moreover, we found a homogenous genetic structure of N. lugens based on pairwise fixation indices (Fst) analyzes that appears to be maintained by high levels of gene flow and showed no correlation between genetic and geographical distance. Importantly, these studies also support accurate information of widely distributed and genetically intermixed among N. lugens across Asia populations. Thus, our results support the theory of long-distance migration among N. lugenspopulations. The genetic structure information of N. lugens in Java could support regional management, such as the new controlling strategies based on forecasting systems.

Main insect pollinator of chayote in the neotropics is the stingless bees. In Indonesia, there is no information available on chayote pollination. Research was conducted with the objective to study the flowering phenology of chayote and the role of two specieses of stingless bees Heterotrigona itama (Cockerell) and Tetragonula laeviceps (Smith) (Hymenoptera: Apidae) on chayote pollination. Measurements included the number of staminate and pistillate flowers, volume of nectar and sugar concentration, floral handling time and visitation rate, and fruit set. Chayote plants produced more staminate flowers than pistillate flowers, with the ratio of 18:1. There was no difference in nectar volume and sugar concentration between staminate and pistillate flowers. H. itama and T. laeviceps visited both type of flowers, with the peak of daily visitation were occurred at 08:30-10:30 am local times. There were significant differences in the floral handling time and foraging rate of H. itama and T. laeviceps. Pollen load was significantly higher in H. itama (2137.50±184.49 grains) than those in T. laeviceps (1675.00±110.47 grains). H. itama seemed to deposite more pollen (14.1±4.1 grains) on stigma than T. laeviceps (9.8±3.1 grains). Flowers prevented from insect visits resulted in zero fruit set. Single flower visit by H. itama and T. laeviceps resulted in 60 and 40% fruit set, respectively. Higher percent of fruit set (80-85%) was noticed in open-pollination, suggesting that multiple visits by insect pollinators might increase the chances of successful pollination.

Aphid is a sucking insect as a pest and vector of virus diseases plants. The aphids presence on plants are often accompanied by ants that symbiotic on aphid’s colony. Mutualism symbiosis between ants and aphids can hinder natural enemies especially parasitoids to parasitizing aphids. This study aims to explore parasitoid and ant species associated with aphids and determine the level of parasitoid parasitization. The survey was conducted on agricultural crops and weeds in West Java area. Samples were taken by purposive sampling looking at the aphid presence, ant, and mummified colonies. Aphid’s identification was carried out at Insect Biosystematics Laboratory, Department of Plant Protection IPB, whileparasitoid and ant identification was carried out at Entomology Laboratory of Zoology LIPI. The identification results obtained four species of Hymenoptera parasitoid, i.e Adialythus ambiguus, Aphidius matricariae, Praon absinthi (Braconidae) and Psyllaephagus pilossus (Encyrtidae) and eight species of ants of Formicidae family, i.e Dolichoderus sp, Dolichoderus thoracicus, Monomorium destructor, Monomorium floricola, Myrmicaria brunnea, Pheidole javana, Polyrhachis dives, and Technomyrmex albipes. The dominant parasitoid species found was A. matricariae, but the highest level of parasitization was P. pilossus (78%), parasites Rhopalosiphum padi in rice plants. Basic information on the types of ants and parasitoid insects associated with aphids can be used in the development of aphids integrated pest management strategies.

The research was conducted in sub-district of Ciledug (Cirebon) with the objectives to study the infexiation and larvaal population development id onion armyworm. Spodoptera exigua (Habner) (Lepidoptera: Noctuidae), on shallots grown in lowland. Monitoring of egg masses and leaf damage were made at 3-4 days internal while of larvae at 1 week internal. Outbreak took place during the dry season of August-October 1995 when population density reached 0.8 egg mass and 23 larvae per hill, and subsequently all hills were heavily damaged. Throughout the rainy season of December 1995-February 1996, egg masses and larvae were difficult to find. Result of hand-picking showed that larval population during dry season was 78 times higher than those of rainy season. Larvae exhibited body color vartations. During the epidemics 80 percent of the larvae were dark whereas,during the endemics only 10 percent, the rest were light green. Level of egg parasitization was 0,9 percent coused by Tricogramma xp. (Hymenoptera; Trichogrammatidae) and telenomus sp. (hy menoptera; sceltonidae ), and larval parasitization 5.7 percent coused by Microplitis sp. (Hymenoptera; Braconidae), Euplectrus sp. and stenomesius sp (Hymeno[tera; Eulophidae), and Peribaea sp. (Diptera; Tachinidae). Low level of parasitization together with the abundance of food supply and dry season were believed to be the main foctors contributing to the population outbreaks. Hand-picking of egg masses and larvae conducted regularly, as practiced by the farmer group in the village of Dukuh wringin (Brebes(, should be adopted as a key activity for mitigating S. exigua infestation during dry season; and therefore, this practice should disseminated to farmers in other areas.
