Abstract/ Executive Summary:

Several sap-sucking insects (Hemiptera: Sternorrhyncha) of neotropical origin have been accidentally introduced to Southeast Asia and West Africa in recent years, including the mealybugs Paracoccus marginatus Williams & Granara de Willink, Phenacoccus madeirensis Green, Phenacoccus manihoti Matile-Ferrero, Phenacoccus solenopsis Tinsley, Pseudococcus jackbeardsleyi Gimpel & Miller, and the whitefly Aleurodicus dugesii Cockerell (Aleyrodidae). This paper documents new distribution records of introduced mealybugs and some other sap-sucking hemipteran insects (Coccidae and Diaspididae) in these regions and discusses progress in the biological control of some of these pests.

Start Date: 16-10-2008

End Date: 19-05-2009

Program Area: Pest Management

Commodity: Insects

Objectives:

To know the status of papaya mealy bug in context of other countries of Southeast Asia and West Africa

Methodology:

During recent visits to Southeast Asia by scientists from Virginia Polytechnic Institute and State University and Clemson University who were participating in a USAID-funded Integrated Pest Management Collaborative Research Support Program (IPM CRSP), heavy infestations of sap-sucking insects Hemiptera: Sternorrhyncha were sampled and subsequently identified. Samples from West Africa were collected by scientists from the International Institute for Tropical Agriculture in the Republic of Be´nin. Most of these pests are of neotropical origin and they have been accidentally introduced into these tropical regions in recent years. They are actively extending their geographical ranges and they sometimes cause significant damage to important crops by direct feeding, and indirectly by deposition of honeydew that gives rise to sooty mold growth, which blocks light and air from the leaves and reduces photosynthetic productivity. Contacts within host countries submitted additional samples, some of which were new country records. Bangladesh.
