Fine structure of the preocellar pit in Trissolcus basalis (Woll.) (Hymenoptera : Scelionidae)
International Journal of Insect Morphology and Embryology, 1994Abstract The preocellar pit of both sexes of Trissolcus basalis (Hymenoptera : Scelionidae), a solitary egg parasitoid of Nezara viridula , is described. Externally, the opening is median, spherical, with an average diameter 12 μm Internally, the preocellar pit corresponds to a bell-shaped apodeme (27 μm deep) with smooth cuticular walls, except ...

Patch Defence in the Parasitoid Wasp Trissolcus Basalis: When to Begin Fighting?
Behaviour, 1998AbstractForagers that exploit defendable patches are faced with a trade-off, between exploiting the patch, and defending it against competitors. In insect parasitoids, this trade-off is compounded by the fact that the host resources are not consumed, but remain in the environment after being exploited and therefore are still vulnerable to attack by ...

Abstract Teratocytes may control the physiology of the host and/or have trophic or secretory functions that may nutritionally affect the development of their associated parasitoid. The importance of these cells for the development of parasitoids in artificial diets has been investigated and in some cases they have been shown to improve the growth and

Effect of plant nectars on adult longevity of the stinkbug parasitoid,Trissolcus basalis
International Journal of Pest Management, 2005Abstract The egg parasitoid Trissolcus basalis (Wollaston) (Hymenoptera: Scelionidae) is an important biological control agent of stinkbugs worldwide. Although honey has been used as adult food in culturing the parasitoid, no previous studies have explored the potential for maximising its fitness by provision of plant nectars in conservation biological

Parasitoids are widely used as biological control agents to manage insect pest populations in greenhouses. To meet their energetic and nutritional requirements, adult parasitoids consume carbohydrate‐rich sources such as (extra‐)floral nectar and ...

An upsurge of macadamia stink bug (Bathycoelia distincta Distant) in Kenya has resulted in severe damage to macadamia nuts. Its management is best achieved through use of egg parasitoid, Trissolcus basalis, commonly used across the globe.

AbstractThe lethal doses of the pyrethroid deltamethrin were estimated for the egg parasitoid Trissolcus basalis (Wollaston) (Hymenoptera: Scelionidae), and the sub‐lethal effects of an LD25 on female walking behaviour were evaluated. Linear speed of treated parasitoids was reduced compared with that of untreated ones for a period of up to 24 h.

In vitro rearing ofTrissolcus basalis [Hym., Scelionidae] an egg parasitoid ofNezara viridula [Hem., Pentatomidae] [PDF]
Entomophaga, 1992 In vitro rearing of the egg parasitoidTrissolcus basalis (WOLL.) from eggs collected on the natural hostNezara viridula (L.) was initiated. Several oligidic diets containing insect material (Manduca sexta hemolymph or host egg content) were tested.

The ability of host discrimination allows insect parasitoids to avoid superparasitism (oviposition in a previously attacked host). However, superparasitism can sometimes be adaptive, so attempts to identify host discrimination must be made under appropriate ecological conditions.
