Parasitoid of cassava mealybug, Anagyrus lopezi (Hymenoptera: Encyrtidae): Mummy size, adult emergence, sex ratio, and parasitization level

PHYSIOLOGICAL ECOLOGY Influence of Temperature, Nourishment, and Storage Period on the Longevity and Fecundity of the Mealybug Parasitoid, Anagyrus sp. nov. nr. sinope Noyes and Menezes (Hymenoptera: Encyrtidae)

Anagyrus sp. nov. nr. sinope Noyes and Menezes (Hymenoptera: Encyrtidae) is a candidate for biological control of theMadeiramealybug,PhenacoccusmadeirensisGreen (Hemiptera: Pseudococcidae). P. madeirensis is a serious pest of horticultural crops in the southeastern United States. The Þrst experiment studied the effect of temperature (15, 20, 25, 30, and 35 C) and feeding treatment (starved, hyd...

Description of a new species of Anagyrus Howard (Hymenoptera: Chalcidoidea: Encyrtidae), a promising biological control agent of the invasive Madeira mealybug, Phenacoccus madeirensis Green (Hemiptera: Sternorrhyncha: Pseudococcidae).

Anagyrus amnestos sp. n. (Hymenoptera: Encyrtidae), a promising parasitoid of the invasive Madeira mealybug, Phenacoccus madeirensis Green (Hemiptera: Pseudococcidae), is described based on material collected from India. This parasitoid was identified as Anagyrus sp. nov. nr. sinope Noyes & Menezes in recent literature, and was initially collected in Georgia, USA. It was found to be a specific ...

Effects of temperature and host stage on the parasitization rate and offspring sex ratio of Aenasius bambawalei Hayat in Phenacoccus solenopsis Tinsley

Temperature and host stage are important factors that determine the successful development of parasitoids. Aenasius bambawalei Hayat (Hymenoptera: Encyrtidae) is a primary parasitoid of the newly invasive mealybug, Phenacoccus solenopsis Tinsley (Hemiptera: Pseudococcidae). The effects of temperature on the parasitic characteristics of A. bambawalei have seldom been investigated. In the study, ...

Sex ratio in the aphid parasitoid Aphidius colemani (Hymenoptera: Braconidae) in relation to host size.

Economics of biological control of cassava mealybug in Africa

Pest populations of the cassava mealybug Phenacoccus manihoti Mat.-Ferr. (Homoptera: Pseudococcidae) were reduced successfully by the biological control agent Apoanagyrus (Epidinocarsis) lopezi De Santis (Hymenoptera: Encyrtidae) throughout most of sub-Saharan Africa. The economics of the project were evaluated based on data from field trials, socio-economic surveys, published results, and fina...
