Reproductive attributes and functional response of Anastatus japonicus on eggs of Antheraea pernyi, a factitious host [PDF]

open access: yesPest Management Science, 2022
Single 1‐day‐old mated Anastatus japonicus females exhibited a type II functional response to increasing host densities (1–50 Antheraea pernyi eggs), with an inverse host density‐dependent pattern of percent parasitism. The upper limit to the daily attack rate was estimated as 7.6 Antheraea pernyi eggs.

Effects of Cold Storage on Host Antheraea pernyi Egg Quality for the Egg Parasitoid Anastatus fulloi Sheng and Wang [PDF]

open access: yesInsects, 2021
Chinese silkworm (Antheraea pernyi) eggs are used as factitious hosts of Anastatus fulloi, and refrigeration of these eggs is essential for large-scale rearing of A. fulloi. We studied the effects of cold storage of A.

Mechanisms Responsible for Larval Diapause in Anastatus japonicus Ashmead, Shown by Integrated Transcriptomic and Proteomic Analyses [PDF]

open access: yesInsects
Diapause enables insect survival in unfavorable environments. The parasitic wasp A. japonicus, a natural enemy of several fruit-tree pests, undergoes larval diapause. Previous work has shown that larval diapause in A.

Courtship Is a Major Factor of Mating-Shortened Male Lifespan in an Egg Parasitoid. [PDF]

open access: yesEcol Evol
Mating is vital for population survival but often leads to reduced post‐mating longevity in both sexes. In many insects, sperm‐related factors are thought to cut male longevity, while in Anastatus disparis, mating also affects male longevity, with courtship being the main cause. Transcriptomic analyses of A.
