Book Description
This book uses the unique expertise of leading rice entomologists from Africa, Asia and the Americas to provide the first global coverage of rice insect pests. The groups of insects discussed are : Root and stem feeders, Stem borers, Rice gall midges, Leafhoppers and planthoppers, Foliage feeders and, finally, Panicle feeders. The book concludes with a discussion of integrated management of insect pests.
Rice-feeding Insects of Tropical Asia

ISBN: 9712200620
Category : Insect pests
Languages : en
Pages : 236
Book Description
The field guide documents the community of insects that feed on rice in the tropical zone of Asia and complements the IRRI publication "Helpful insects, spiders, and pathogens: friends of the rice farmers." It covers 78 phytophagous species in 64 genera, 27 families, and 8 orders. The phytophage guild represents five groups-general defoliators, (27 species), plant suchers (25 species), early vegetative pests (11 species), soil pests (9 species), and stem borers (6 species). Stem borers and plant suckers comprise the major rice pests. A brief description of each insect's life stage and demage it does to the rice plant is presented for a quick and reliable identification.

The Economics of Integrated Pest Control in Irrigated Rice

Pages : 207
Book Description
As a result of the green revolution, the use of yield-increasing inputs such as fer tilizer and pesticides became a matter of course in irrigated rice farming in Southeast Asia. Pesticides were applied liberally, both as a guarantee against crop failure and as a means of fully utilizing the existing yield potential of the crops. However, since outbreaks of pests, such as the brown planthopper (BPH) or the tungro virus, continued to occur despite the application of chemicals, a change of approach began to take place. It is now being realized more and more in Southeast Asia that crop protection problems cannot be resolved solely by the application of chemicals. In the past several years, increasing efforts have there fore been made to introduce, as a first step, supervised crop protection, leading gradually to integrated pest management (Kranz, 1982). Although the crop protection problems naturally differ in the different devel oping countries in Southeast Asia, the economic situation prevailing in these countries can nevertheless be regarded as an important common determinant: pesticide imports use up scarce foreign currency and thus compete with other imports essential to development. For the individual rice farmer, the problem is basically the same: his cash funds are limited and he must carefully weigh whether to use them for purchas ing pesticides, fertilizer or certified seed. In view of this constraint, it is becom ing necessary to abandon the purely prophylactic, routine calendar spraying and instead, employ critically timed and need-based pesticide applications.
