Although control of insects, pests and weeds has remained the major effective plant protection tool, yet hazards to environmental safety urge the scientific community to propose alternative pest management strategies. 2. Distribution of rice stem borers and their parasitoid in Kilombero Morita’s dispersion index for stem borer larvae indicated that there was more number of stem borer larvae at rice vegetative stage in three wards of Signali, Mkula and Sanje with an aggregate distribution of both stem borer larvae and parasitoids (Table 1).

During a capacity-building program, IPM practices with strong cultural and biological control-based components were promoted among ca 50 IPM trainers and ca 6,400 rice farmers. Apprehensions about conventional agriculture sustainability have impelled the extensive introduction of integrated pest management (IPM). Potential effects are difficult to assess not only because of the uncertainty in the magnitude of changes in climate variable, but also because uncertainties in crop responses to weather, soil and management factors. crops so to control the damages caused by these insects it requires greater commu-, the panicle has come out. The yellow stem borer (YSB), Scirpophaga incertulas , is a prominent pest in rice cultivation causing serious yield losses. trailer Field evaluation of two egg parasitoids, Trichogramma japonicum Ashmead against rice stem borer, Scirpophaga incertulas (Walker), and Trichogramma chilonis Ishii against leaf folder, Cnaphalocrocis medinalis (Guenee), was carried out in farmers' fields in three locations at Karakkad village, Palakkad district, Kerala, during three seasons in 2003 and 2004 in … 3.1. xÚb```b``áe`e`àdd@ A +ÇGc ªlÃ,9ѤQ@Ã2dÚÚ35Ê\¸øBUÏdÝç85YàÊ$}µ©¼ 2011;101:696–709. Chilo suppressalis (Walker, 1863) is a serious stem borer of rice and water-oat plants, and has phenotypically diverged into rice and water-oat populations. In this study, the bulbils of aerial yam (Dioscorea bulbifera L.) were investigated for their potential for biosynthesis of silver nanoparticles. Pest insects are considered throughout the world as a major limitation to the production of irrigated rice crops. Functional analysis of eight chitinase genes in rice stem borer and their potential application in pest control: Function Analysis of Eight Chitinase Genes Rice production systems have threatened with insect pests and weeds that significantly contribute to yield losses. Four TRFs were established in each of the participating countries. Funded by the European Union (EU), this IPM initiative brought together local and international partners to develop an environmentally friendly and economically sustainable rice pest management strategy for southwestern China, Laos, and Myanmar. Abstract. Cereals (maize, sorghum, millet, rice) are extremely important crops grown in Africa for human consumption. Resistance of different Basmati rice varieties to stem borers under different control tactics of BIPM and evaluation of yield. xref Any reduction in enemy number can result in an insect outbreak. Applied biological control is thus one strategy for restoring functional biodiversity in many agroecosystems. Predators and Parasitoids addresses the role of natural enemies i Remote Sens. The rice stem borer and brown plant hopper have the largest share. Although biological control using indigenous and exotic parasitoid wasps and flies has had some success in Florida and the Lower Rio Grande Valley in Texas [ 43 , 70 ], it has been less effective in other regions of the United States [ 71 ]. 0000105646 00000 n Kaur R, Brar KS, Singh J, Shenhmar M. 2007. 0000051711 00000 n An egg parasitoid, Trichogramma, is used for management of lepidopteran pests of rice worldwide.

Pesticides in the form of fungicides, herbicides and insecticides are contributing a huge part in rice production and around USD5.37 million are spent on them annually. TM. However, the continuous use of phytosanitary products induce resistance formation in the targeted insect, Eco-friendly tactics of pest management in vegetables have special significance not only for reduction in pesticide residues but also to maintain the natural enemy activity and making the production system more sustainable.
