Therophilus javanus is a koinobiont, solitary larval endoparasitoid currently being considered as a biological control agent against the pod borer Maruca vitrata, a devastating cowpea pest causing 20–80% crop losses in West Africa. We investigated ovary morphology and anatomy, oogenesis, potential fecundity, and egg load in T. javanus, as well as the effect of factors such as age of the female and parasitoid/host size at oviposition on egg load. The number of ovarioles was found to be variable…

Progeny fitness determines the performance of the parasitoid Therophilus javanus, a prospective biocontrol agent against the legume pod borer
TLDR
Therophilus javanus is an exotic larval endoparasitoid newly imported from Asia into Africa as a classical biological control agent against the pod borer Maruca vitrata and their influence on progeny sex ratio was assessed together with the impact of larval host age at the time of oviposition on development time, mother longevity and offspring production.
Courtship, Mating Behavior, and Ovary Histology of the Nymph Parasitoid Psyllaephagus bliteus (Hymenoptera: Encyrtidae)
TLDR
The courtship, male competition, and mating behavior of P. bliteus at the proportions of 1:1 and 2:1 males to female in a Petri dish is analyzed, and the ovary histology of virgin and mated females of this parasitoid is described.

Biology of Agathis gibbosa (Hymenoptera: Braconidae), a Primary Parasite of the Potato Tuberworm
Agathis gibbosa (Say), a primary, solitary, larval endoparasite of Phthorimaea operculella (Zeller) (Lepidoptera: Gelechiidae), was studied under laboratory conditions of 26.7 ± 1°C and 50 ± 2%, RH.
Oogenesis pattern and type of ovariole of the parasitoid Palmistichus elaeisis (Hymenoptera: Eulophidae).
TLDR
The findings can help to improve the mass production of P. elaeisis and the augmentative biological control by using this natural enemy.
Does Host Size and Feeding Status Influence the Egg Load of Microplitis rufiventris (Hymenoptera: Braconidae)?
TLDR
Male wasps that developed from fourth or fifth instars of Spodoptera littoralis (Boisduval) larvae were heavier in weight than those from earlier stages, suggesting that they produce a certain portion of eggs from nutritional reserves that had been stored during larval stage.
Venturia canescens parasitizing Galleria mellonella and Anagasta kuehniella: differing suitability of two hosts with highly variable growth potential
TLDR
It is argued that patterns of host utilization and resource acquisition by parasitoids have evolved in accordance with host growth potential and the nutritional requirements of the parasitoid.
Effect of food, light and host instar on the egg load of the synovigenic endoparasitoid Venturia canescens (Hymenoptera: Ichneumonidae)
TLDR
Host instar, food supplement and photoperiod could have potential for improving biological control efficacy in stores, however, further studies determining the effect of these factors on egg laying behavior and fecundity should be done.
Importance of Alternative Host Plants for the Annual Cycle of the Legume Pod Borer, Maruca vitrata Fabricius (Lepidoptera: Pyralidae) in Southern and Central Benin
TLDR
The use pattern of alternative host plants by Maruca vitrata was investigated in southern and central Benin and this pest was able to maintain high population levels exclusively on wild hosts without needing to switch to cultivated crops.

INSECT PARASITOID COMPOSITION ON SOYBEAN, SOME ECO-BIOLOGICAL CHARACTERISTICS OF THE PARASITOID, XANTHOPIMPLA PUNCTATA FABRICIUS ON SOYBEAN LEAFFOLDER OMIODES INDICATA (FABRICIUS) IN HANOI, VIETNAM
TLDR
Food quality affected adult longevity, as individuals which were fed pure honey lived for an average of 8.5 days compared to those fed with 50% honey solution, and those fed pure water lived for only 2.6 days.
The biology of the parasites of Loxostege sticticalis, L., in North America; Bracon vulgaris (Cress.) (Braconidae, Agathinae).
TLDR
The habits and life-history of another important parasite of Loxostege in North America, Bracon vulgaris (Cress.), appears to be confined to the American continent.
Nutritional Ecology of an Insect Host‐Parasitoid Association: The Pea Aphid‐Aphidius Ervi System
TLDR
It is proposed that, for parasitoids developing in growing and feeding stages of the host, host quality is not a linear function of host size at parasitization but reflects the degree of integration of the two systems.
