Abstract Surveys were carried out in Zambia twice yearly from 1986 to 1990, to assess the impact of a biological control campaign against the cassava mealybug (CM), Phenacoccus manihoti Mat.-Ferr., throughout the infested area. From 1984 onward, the exotic parasitoid Epidinocarsis lopezi (De Santis) (Hym., Encyrtidae) and some exotic coccinellid ...

Continental-scale suppression of an invasive pest by a host-specific parasitoid underlines both environmental and economic benefits of arthropod biological control [PDF]
Biological control, a globally-important ecosystem service, can provide long-term and broad-scale suppression of invasive pests, weeds and pathogens in natural, urban and agricultural environments.

AbstractThe ultrastructure of the sensory receptors located on the labium of the cassava mealybug Phenacoccus manihoti Matile‐Ferrero (Homoptera, Pseudococcidae) was studied with scanning and transmission electron microscopes. Trichoid hairs of probable mechanoreceptive function are distributed over the labium.

The mean critical thermal maxima varied significantly across species with Delottococcus aberiae showing the highest heat tolerance, whereas Planococcus citri recorded the lowest. All mealybug species exhibited substantial contractions in climatically suitable areas by 2100, with Pseudococcus calceolariae recording the greatest proportional decline ...

This field mesocosm study examined the top‐down effects of hyperparasitoids, parasitoids and aphids on plant growth and fitness. Parasitoids reduced aphid populations, but this effect was attenuated by hyperparasitoids. However, these multitrophic interactions did not affect plant traits and reproduction, likely due to the plant's fast life cycle and ...

Epidinocarsis lopezi an exotic parasitoid to Africa, was first released to control the cassava mealybug (CM), Phenacoccus manihoti, at IITA (Ibadan) in November 1981, and a year later at Abeokuta, both in southwestern Nigeria. Population dynamics study of CM and its natural enemies was conducted for 4 years.
