| dc.description.abstract | In laboratory experiments with Epidinocarsis lopezi, a parasite that has been introduced into Africa for the biological control of Phenacoccus manihoti on cassava, hosts of different stages that had been stung by a female parasite were inspected after 6 and 20 days. The killing power of the parasite was several times as high as the production of parasite offspring. Host feeding and mutilation were responsible for 1-22 and 11-34% mortality, respectively. Both were significantly higher on younger than on older hosts. Of mealybugs that were stung, 11-33% yielded live parasites; parasite reproduction was significantly more successful in older than in younger hosts. Of all the hosts, 30-56% survived a single oviposition attempt by the parasite; mortality in unstung mealybugs was 4-8%. |
