The adult, egg, and larval stages of P. palitans are described, and the adult, male genitalia, ovaries (and associated structures), egg, first-, second-, and third-instar larvae and head structures are illustrated. Unmated females of P. palitans produce only males, mated females produce progeny in a sex ratio of 1:1, but multimated males supply so little sperm at each mating that the sex ratio may go as high as 58:1 in favor of males. The parasite oviposits in aphids of any stage, but… 
Immature Morphology and Development of Opius caricivorae (Hymenoptera: Braconidae), an Endoparasitoid of the Leafminer Liriomyza sativae (Diptera: Agromyzidae)
Abstract The immature development and morphological characteristics of Opius caricivorae Fischer (Hymenoptera: Braconidae), an endoparasitoid of dipteran leafminers, were studied under laboratory
Larval morphology and development of Aphidius rhopalosiphi (Hymenoptera: Braconidae: Aphidiinae)1
The "three instars" hypothesis is supported here by the observation of larvae in exuviation, supporting the idea that species of this genus cannot be distinguished by larval morphology but only by morphometric analysis.
The effects of parasitism by an encyrtid parasitoid, Anagyrus pseudococci on the survival, reproduction and physiological changes of the mealybug, Planococcus citri
SDS‐PAGE analysis of the body content of the parasitized mealybugs after 24 h and 48 h of parasitization and before egg hatch revealed an increase in the concentration of some proteins and the possible effect of parasitism on the changes of the reproductive physiology of the host is discussed.
The effects of two species of hymenopterous parasitoid on the reproductive system of the pea aphid, Acyrthosiphon pisum
Results suggested that embryonic degeneration was an indirect effect of parasitization due to starvation, interference with the aphid's hormone levels, or both.
Duration of development and longevity inAphidius ervi andAphidius platensis [Hym.: Aphidiidae], two parasites ofMyzus persicae [Hom.: Aphididae]
Differences in longevity between the sexes were small and dependent on temperature and food, and was not significantly influenced by the different host plants during parasite development.
Biology, Ecology and Control Efficiency of the Aphid Parasitoid Trioxys indicas: a Review and Bibliography
The courtship and mating behaviour, host selection, fecundity, oviposition pattern, development, longevity, sex ratio and density responsiveness behaviour as well as various physico-chemical and biological factors influencing the biology of the parasitoid are described and compared with other aphidiids.
Courtship behavior in the Aphytis lingnanensis group, its potential usefulness in taxonomy, and a review of sexual behavior in the parasitic Hymenoptera (Chalcidoidea: Aphelinidae)
Quantitative analysis of courtship behavior revealed that it is possible to separate A. lingnanensis from A. melinus on the basis of overt male behavior and female response to male behavior, and indicated that antennae are essential for successful copulation.
The systematics and taxonomy of final-instar larvae of the family Aphidiidae (Hymenoptera).
Characteristics of cephalic structures and spiracles of final-instar larvae of 65 species in 18 genera of the family Aphidiidae (Hymenoptera) are described and illustrated and keys are given for
Greenbugs [Hom.: Aphididae] forced from host plants byLysiphlebus Testaceipes [Hym.; Braconidae]
To determine the fate of greenbugs leaving plants on hot, sunny, summer days, a small field test was performed in which greenbugs were knocked from plants onto soil exposed to direct sunlight.
