Repeated sampling of rural maize stores in Benin was conducted to evaluate published parameters of a sequential sampling plan for a negative binomial distribution to determine pest status for Prostephanus truncatus (Horn) and Sitophilus zeamais Motschulsky. A computer program was used to rerandom...

Field surveys were conducted on cowpea and pigeon pea in 1995 and 1996 to assess the effect of indigenous egg parasitoids on populations of Clavigralla tomentosicollis Stål in northern Nigeria. From the egg masses of C. tomentosicollis, three species of Hymenoptera belonging to three families, na...

The banana weevil Cosmopolites sordidus Germar, has evaded all efforts to manage it in all banana-based cropping systems except the commercial plantation banana system, where the 2 to 3 year crop cycle and the intensity of management limit the pest survival in that system. Conversely, in backyard...

Rice insect pest management in Nigeria is compartmentalized; literature documenting the status of research on the biology and significance of insect pests and on their management, has therefore been reviewed. A holistic, broadly based, multidisciplinary pest-management research approach is sugges...

High-yielding varieties and improved agronomy have led to substantial increases in cassava crop productivity throughout Southeast Asia; however, in recent years, those advances are being jeopardized by recurrent outbreaks of several non-native arthropod pests and (insect-vectored) pathogens. In t...
