Progeny Fitness of the Mealybug Parasitoid Anagyrus sp. nov. nr. Sinope (Hymenoptera: Encyrtidae) as Affected by Brood Size, Sex Ratio, and Host Quality

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 ...

Brood size and sex ratio in response to host quality and wasp traits in the gregarious parasitoid Oomyzus sokolowskii (Hymenoptera: Eulophidae)

This laboratory study investigated whether the larval-pupal parasitoid Oomyzus sokolowskii females adjust their brood size and sex ratio in response to body size and stage of Plutella xylostella larval hosts, as well as to their own body size and the order of oviposition. These factors were analyzed using multiple regression with simultaneous entry of them and their two-way interactions. Parasi...

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

The effect of buckwheat flowers and cahaba vetch extrafloral nectaries on fitness of the vine mealybug parasitoid Anagyrus pseudococci (Hymenotpera: Encyrtidae)

The effect of access to buckwheat flowers (Fagopyrum esculentum Moench; Polygonales: Polygonaceae) or vetch extrafloral nectaries (Vicia sativa L. cv. ‘cahaba white’; Fabales: Fabaceae) on the fitness of Anagyrus pseudococci (Girault) (Hymenotpera: Encyrtidae) (a parasitoid of the vine mealybug, Planococcus ficus [Signoret]) (Hemiptera: Pseudococcidae) was determined in the laboratory. Female A...
