Genetic evaluation for insect resistance in rice
Genetic evaluation for insect resistance in rice shows positive results for maize with high resistance to E.coli, while in rice with low resistance, the results are negative for other crops. Expand
Illustrated guide to integrated pest management in rice in tropical Asia.
This guide to integrated pest management in rice in tropical Asia shows how rice cultivation and management techniques can be influenced by environmental factors such as temperature and agricultural practices. Expand
PARASITOIDS AND PARASITES OF SPODOPTERA FRUGIPERDA (LEPIDOPTERA: NOCTUIDAE) IN THE AMERICAS AND CARIBBEAN BASIN: AN INVENTORY
An acugutturid, Noctuidonema guyanense (Remillet & Silvain), is the most important ectoparasitic nematode attacking adults of FAW and other noctuid moths in North America, Caribbean Basin, Central America, and Northern South America. Expand
Rice-feeding insects and selected natural enemies in West Africa: biology, ecology and identification.
Perspectives and directions for the continued development of insect-resistant rice varieties
- E. Heinrichs
- 1 October 1986
Efficient methods for screening the world collection of rices have been developed and utilized to identify sources of resistance to 32 rice insect species and strategies for overcoming constraints to the breeding and utilization of insect-resistant rice varieties are discussed. Expand
Levels of Tolerance and Antibiosis in Rice Varieties Having Moderate Resistance to the Brown Planthopper, Nilaparvata lugens (Stål) (Hemiptera: Delphacidae)
Rice varieties having a moderate level of resistance to the brown planthopper, Nilaparvata lugens, were evaluated to determine the mechanisms of resistance and the resistance in ‘IR46,’ ‘Kencana’ and ‘Triveni’ is due to a combination of antibiosis and tolerance. Expand
From secondary to major pest status: the case of insecticide-induced rice brown planthopper, Nilaparvata lugens, resurgence.
Economic Injury Levels for the Rice Leaffolder Cnaphalocrocis medinalis (Lepidoptera: Pyralidae): Insect Infestation and Artificial Leaf Removal
Economic injury levels for the leaffolder Cnaphalocrosis medinalis Guenee on rice variety IR36 were determined as based on percentage of leaves damaged and on number of larvae per plant and indirectly estimated based on larval density by measuring the yield loss at different levels of artificial defoliation. Expand
Factors Affecting Insecticide-Induced Resurgence of the Brown Planthopper, Nilaparvata lugens on Rice
Reduction in the length of the nymphal stage and increased adult longevity resulting in a shortened life cycle and longer oviposition period respectively, were additional factors contributing to resurgence. Expand
