Comparative Biology of Three Geographic Populations of Trissolcus basalis (Hymenoptera: Scelionidae)
Environmental Entomology, 1990Laboratory studies were conducted to determine if there were biological or behavioral differences among populations of Trissolcus basalis (Wollaston) (Scelionidae: Hymenoptera) collected from France, Italy, and Spain. Observations of isolated and mated females indicated little difference in fecundity, adult longevity, male and female progeny produced ...

Source of an egg kairomone for Trissolcus basalis, a parasitoid of Nezara viridula
Physiological Entomology, 1993Abstract. The eggs of the southern green stink bug, Nezara viridula (L.) (Hemiptera: Pentatomidae), are successfully attacked by Trissolcus basalis (Woll.) (Hymenoptera: Scelionidae) and are recognized as hosts by a secretion applied

Agricultural and Forest Entomology, 1999 1. Species of bugs (Hemiptera: Pentatomidae and other families) that are parasitized by the egg parasitoid Trissolcus basalis (Wollaston) (Hymenoptera: Scelionidae) in the soybean agricultural system on the Darling Downs in south-eastern Queensland ...

Journal of Chemical Ecology, 2007 Contact kairomones from adult southern green stink bugs, Nezara viridula (L.) (Heteroptera: Pentatomidae) that elicit foraging behavior of the egg parasitoid Trissolcus basalis (Wollaston) were investigated in laboratory experiments.

Effect of Insecticide Applications in Soybeans on Trissolcus basalis (Hymenoptera: Scelionidae)
Journal of Economic Entomology, 1989Field studies were conducted to determine the effect of the primary insecticides that are applied to control Louisiana soybean insect pests on the survival of an important biological control agent of stink bugs (Hemiptera: Pentatomidae). Adult egg parasitoids, Trissolcus basalis (Wollaston), were affected little by permethrin field applications, but ...

Journal of Insect Physiology, 2001
After oviposition, Trissolcus basalis females always mark the host's surface, depositing host marking substances for herself and to warn other ovipositing females. The perception of these host marking substances, probably through the antennae, can induce the female to leave and seek healthy hosts.

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 ...

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 ...

Biological Control, 2001
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

Phytoparasitica, 2018
Biological control of phytophagous bugs in soybean crops is efficiently performed by egg parasitoids, such as Telenomus podisi and Trissolcus basalis. Based on this, the use of agrochemicals in these crops must be managed consciously, making use of pesticides that are selective to the egg of these parasitoids, in order to ensure a balanced ecosystem ...
