Abstract

Research on natural enemies of Bemisia tabaci was conducted in the chili pepper fields in Sub-district of Pakem, District of Sleman, The Special Province of Yogyakarta during the dry season of May-October 2009. The aims of this research were to study the diversity and abundance of parasitoid and predator species associated with B. tabaci. Samplings of insect species were done using yellow pan trap, sweep net, direct observation of insects colonized young leaves, and collection of nymphs for B. tabaci. Measurement of insect diversity was calculated using Shannon’s index diversity and Evenness index. Nine species of insect predator were identified, i.e. Harmonia octomaculata (Fabricius), Menochilus sexmaculata (Fabricius), Scymnus sp., Micraspis inops Mulsant, Coccinella sp. (Coleoptera: Coccinellidae), Paederus fuscipes Curtis (Coleoptera: Staphylinidae), Orius sp. (Hemiptera: Anthocoridae), Linyphiidae sp.1 (Araneae), and Syrphidae sp.1 (Diptera). Eretmocerus sp. (Hymenoptera: Aphelinidae) was the only parasitoid found in the nymphs B. tabaci collected and has the potential to control B. tabaci in the red pepper fields.

Abstract

The research was aimed to determine the susceptibility level rice from the local gogo rice of Subdistrict Tengah Ilir, District Tebo, and Province Jambi to an infestation of S. oryzae pest. The results showed that rice from varieties Tuo and Seribu Naik belong to a category moderate, while rice from varieties Tapang Bedaro and Cemplok belong to a category moderate-susceptible. Rice from varieties Kuku Balam, Rias Besar, Rias Kecil, Korok, Bedaro, Nartih, and Bungin are classified as susceptible to S. oryzae pest infestations.  The result of correlation analysis showed that there was a significant positive correlation between susceptibility index with length rice (r= 0.906**, P<0.01) and shape rice (r= 0.771**, P <0.01) and there was a significant negative correlation with the wide of rice (r= -0.630*, P <0.05).  The susceptibility index was also affected by the number of F1 S. oryzae (r= 0.922**, P <0.01) and a negative correlation was significant with the median development time S. oryzae (r= -0.912**, P<0.01). Dimensions rice such as length rice (r= 0.898**, P<0.01), shape rice (r= 0.911**, P<0.01), and wide rice (r= -0.816 **, P<0.01) also affects the number of F1 S. oryzae of emerging. The dimension of rice is a source of susceptibility to rice against S. oryzae pests.

Abstract

The research of predatory arthropod species diversity in agro-ecosystem is very important because it affects the function of natural enemies in suppressing pest population. Management of paddy through cultivation method can be part of the conservation of predatory arthropods. This study was conducted to analyze and compare the diversity of predatory arthropod with method cultivation conventional and integrated crop management (ICM) and diversity predatory arthropod based on phase growth paddy from cultivation conventional and ICM. The experiment was conducted in lowland rice agro-ecosystem at two plots with conventional cultivation method and ICM. Sampling of predatory Arthropods was done on the phase growth vegetative and generative paddy using net trap, yellow pan trap, and direct observation in the plants. The results showed that the predatory arthropods found were from Insecta and Arachnida class. The species diversity of predatory arthropod at phase growth of generative was higher than vegetative phase both at the conventional and ICM cultivation. Diversity predatory arthropod on the ICM method was higher compared to conventional. Paddy cultivation method with ICM through the rational use of insecticides can be part of conservation for predatory arthropod species.

Abstract

ABSTRACT A research on behavior of pest S. litura on two varieties of soybean has been done in Blang Manyak Village, Sawang Sub district, North Aceh District from January?May 2013. The research was arranged in a field experiment with two treatments of soybean varieties, that is Kipas Merah and Anjasmoro.  Each treatment was repeated 20 times to obtain 40 units of the experiment. Variables measured included damage intensity of S. litura, trichome density of leaves, yield components, and resistance evaluation. The relationships between yield components and damage intensity of S. litura were analyzed with regression and correlation. The results showed that damage intensity of S. litura on Kipas Merah was lower than that on Anjasmoro. Loss of soybean yield components on both varieties was influenced by the damage intensity of S. litura. There was a negative correlation between damage intensity of S. litura and soybean yield components on both varieties.  Kipas Merah was moderately resistant and Anjasmoro was susceptible against S. litura.  Resistance differences of both varieties were influenced by trichomes density of the leaves.

The Interaction Water Deficiency Level and Soybean Varieties [Glycine max (L) Merr] Capacity to the Plant Growth, Product and Prolin ContentABSTRACT. The research was conducted to study the interaction water deficiency level and soybean varieties to capacity of the plant growth, product and prolin content. The experiment as factorial experiment in a completely randomized design was applied. The first treatment factors were three level varieties soybean: Kipas putih, Wilis, and Singgalang. The second factor were four level water deficiency: no water deficiency along the growth period, water deficiency along early vegetative growth period, water deficiency along early active of vegetative growth period, water deficiency along flowering, and forming and seed filling period, and water deficiency along seed maturity period. The results showed the water deficiency along each growth period decreased the growth and production. In contrast the water deficiency increases the plant prolin content. The water deficiency along flowering, forming and seed filling period decreased number of pod of all variety. The variety Kipas Putih decreased about 42.49% were compared to the same criteria with no water deficiency in all growth period where water given in normal amount along the through growth period.
