Paddystem borer (Scirpophaga incertulas) is a serious rice pest. The damaged plants wither into dead tassel or white tassel. Such damage leads to decreased in rice production. In order to control the damages of paddystem borer efficiency, it is very important to analyze and study the regulation of population dynamics and the related factors affecting the development. This investigated the popul...

Cereals (maize, sorghum, millet, rice) are extremely important crops grown in Africa for human consumption. Of the various insect pests attacking cereal crops in Africa, lepidopteran stem borers are by far the most injurious. All 21 economically important stem borers of cultivated grasses in Africa are indigenous except Chilo partellus, which invaded the continent from India, and C. saccharipha...
