Species identification, host range, and identification key of whiteflies of Bogor and surrounding area. Whitefly (Hemiptera: Aleyrodidae) is a group of insects that are small, white, soft-bodied, and easily found on various agricultural crops. Whitefly is a phytophagous insect; some species are important pests in agricultural crops that can cause direct damage and can become vectors of viral diseases. The last few years the damage caused by whitefly in Indonesia has increased. Unfortunately, information about their species and host plants in Indonesia, including in Bogor, is still limited. Kalshoven, in his book entitled Pest of Crops in Indonesia, published in the 1980s reported that there were 9 species of whitefly in Indonesia. The information on the book should be reconfirmed. Therefore, this study was conducted to determine whitefly species and its host plants in Bogor and its surroundings. Whiteflies is identified based on the ?puparia? (the last instar of the nymph) collected from various agricultural plants, ornamental plants, weeds, and forest plants. A total of 35 species of whiteflies were collected from 74 species and 29 families of plants. The collwcted whiteflies consist of four species belong to Subfamily Aleurodicinae and 31 species of Subfamily Aleyrodinae. The most often found whitefly species were Aleurodicus dispersus, A. dugesii, and Bemisia tabaci. A dichotomous identification key of whiteflies was completed based on morphological character of 35 collected species. The number of whitefly species in Bogor and surrounding areas were far exceeded the number of species reported previously by Kalshoven from all regions in Indonesia.

Whitefly (Hemiptera: Aleyrodidae) plays an important role as pest in many horticultural plants (fruits, vegetables, and ornamental plants). The aim of this research was to study whiteflies diversity in horticultural plants on different altitude. Whitefly samples were collected from its host plants in five areas of West Java Bogor, Sukabumi, Cianjur, Bandung, and Garut. The places were grouped into three altitude categories: lowland, midland, and highland. Number of whitefly species and individual were analysed using analysis of variance (ANOVA) with post-hoc Tukey (Î± = 0.05), while the correlation between altitude and whiteflies species number described in linear regression. Species diversity was measured by two types of index (Shannon and Simpson). The highest number of whitefly individual was found in vegetables (121.80). However, the highest number of whitefly species was found in fruits (2.44 species). According to the altitude, the highest number of whitefly species was found in the lowland (4.67 species), whereas the lowest was found in the highland (1.58 species). The abundance of whiteflies population increases with increasing of altitude, whereas the number of species decreases with increasing of altitude. The highest number of whitefly species diversity was found in the lowland (H' = 2.08), meanwhile the lowest was in the highland (H' = 0.38). By contrast, according to the Simpson index, there was species domination of whitefly in the Highland (D = 0.54) by species Aleurodicus dugesii Cockerell

Greenhouse ecosystem with more stable abiotic factors could affect the population and diversity of pests and diseases found on foxtail millet (Setaria italica L. Beauv.) compared to their natural ecosystems. We observed and identified pests and diseases in seven genotypes of foxtail millet namely “Toraja”, “ICERI 5”, “ICERI 6”, “Botok 4”, “Botok 10”, “Mauliru”, and “Hambapraing”; these activities are important for the formulation of appropriate integrated pest management techniques. Using plant samples that were at the end of their vegetative phase, we found white mycelia of Fusarium incarnatum (yellowish-white colonies) and F. verticilloides (violetish-pink colonies) covering the ear-tip of the seeds and developed rapidly leading to seed rotten symptoms in “Toraja”, “ICERI 5”, and “ICERI 6”. The disease severity remained constant after these integrated management techniques were put in place. However, abnormalities in leaves leading to failure of panicle emergence occurred in “Botok 4”, “Botok 10”, “Mauliru”, and “Hambapraing”. These were caused by the fungi Penicillium sp. Identical controlling techniques were applied to this incidence and the disease incidence was reduced. Corn leaf aphids (Rhophalosiphum maidis) and rice mealybugs (Brevenia rehi) were recorded as main insect pests with severe attack. The aphid, R. maidis, colonized the stems and were associated with the sooty mold (Capnodium sp.), resulting in wilting. The mealybugs, B. rehi, colonized the flag leaves resulting in leaf rotting. Insecticide and isolating the attacked plants were used as the controlling techniques. Red-mites (Tetranychus urticae) were also detected as indicated by chlorotic spots on the upper part of the leaves. Acaricide was used to reduce its population. The pests and diseases found in the seven genotypes of foxtail millet are commonly known to occur in Poaceae. In general, greenhouse ecosystem for foxtail millet facilitated planting with high population with lower diversity of pests and diseases compared to the open field planting.

Mulberry plant (Morus alba) is a plant that has social and economic importance. This plant development is often done to harvest the fruit and leaves. The social importance can be found in that this plant, especially in its leaves, is used in silkworm feed (Bombyx mori) and then silk is used in traditional clothes in Indonesia. Cultivation of mulberry plant (leaves and fruit) ideally by Integrated Pest Management (IPM) is necessary so that mulberry plants grow ideally and leaves have high quality and quantity without becoming a source of inoculum for pests and diseases of silkworm maintenance. Mulberry cultivation is generally carried out without using pesticide input so it is interesting in monitoring pests and natural enemies in the mulberry ecosystem. The research was conducted on two varieties of mulberry plants, namely Morus alba var. Kanva-2 and Morus cathayana in the same agroecosystem. Observation of pests and natural enemies was carried out using yellow sticky traps (YST) and pitfall traps (PFT). The orders and families found in the two varieties showed acroceridae family of 37.81% in the YST and hypogastruridae family with a value of 83.76% in the PFT observation.Keywords: IPM, Morus alba, natural enemies, pest, trapping.
