During the past six years, the South-American encyrtid wasp Epidinocarsis lopezi (De Santis) was released from the ground and from the air in about 100 areas in Africa for the biological control of the cassava mealybug (CM) Phenacoccus manihoti Mat.-Ferr. It was established in all release sites a...
The capability of Epidinocarsis lopezi (De Santis) (Hymenoptera: Encyrtidae) to control the cassava mealybug (CM) Phenacoccus manihoti Mat.-Ferr. (Homoptera: Pseudococcidae) was investigated in Nigeria using physical and chemical exclusion experiments. In two sleeve cage experiments CM population...
Cassava mealybugs (CM) of different stages, which had been stung by an E. lopezi female, were inspected after 6 and 20 days. The killing power of the parasitoid was several times higher than the production of parasitoid off-spring. Host-feeding and mutilation were responsible for 6-22% and 11-34%...
Biological control is a significant component of integrated pest management programs around the world. However, uncertainty about the risk of unanticipated effects on non-target organisms is one of the major concerns surrounding the release of biological control agents. This Brief has been prepar...
About 130 species of parasitoids and predators are reported, most of them for the first time, to be associated directly or indirectly with the cassava pest Phenacoccus manihoti Matile-Ferrero and its parasitoid, Epidinocarsis lopezi (De Santis), newly introduced into Africa as a biological contro...
