Insects in the order Hymenoptera defend themselves, attack prey and regulate hosts using toxins that are effective in small quantities. In this study, advances in the researches on parasitic hymenopteran toxins are summarized in terms of the production, categories, components, properties, ecological functions and mechanisms. The glands that produce venoms derive from the ectoderm tissue and evolve from the accessory glands of the reproductive system. Venoms are excreted by the poison gland or…

Results indicate that venom alone from S. guani plays a pivotal role in blocking hosts cellular immune response, serving as a regulator that guarantees the successful development of its progenies.
The influence of aphid parasitoids on the development of their hosts
The results indicate that there is an active factor in the female parasitoid’s venom that disrupts wing development and/or inhibits development to the adult; the loss of activity after treatment at 100 °C or with protease makes it likely that the factor(s) is a protein.

Every planar graph G of maximum degree at least $28$ which contains no isolated edges admits a proper edge colouring c:E to 1,2,\ldots, Delta(G)+1 such that $\sum_{e\ni u}c(e)\neq \sum_{ e\ni v} c(e)$ for every edge $uv$ of $G$.

It is proven that a graph G obtained from any loopless graph H by subdividing each edge with at least one vertex is (1,3)-total weight choosable and (2,2)-totalWeight Choosable, and it is shown that s-degenerate graphs (with s≥2) are ( 1,2s)- total weight choOSable.

A fundamental paradox underlies compatible parasi­ tic relationships including host-parasitoid interactions, i.e. the compatible parasitoid is not eliminated by the cellular immune defenses that protect the host from other incompatible parasitoids.
Host Regulation by Insect Parasitoids
• Biology
The Quarterly Review of Biology
• 1980
The physiological and biochemical changes that occur after parasitoidism are described and include changes in hemolymph solutes, proteins, carbohydrates, lipids, nitrogen metabolism and excretion, as well as changes in select tissues including the endocrine and reproductive system of the host.
Host Suitability for Insect Parasitoids
• Biology
• 1980
The coevolution of the parasitoid and host has resulted in a number of unique associations and whether a parasitoids is able to develop within a host may depend on the ability or inability of the parasites to regulate the host's physiology.

The effect of the venom of the ectoparasitoid Catolaccusgrandis (Burks) on boll weevil, Anthonomus grandis grandis Boheman growth, development, and survival, and parasitoid development were investigated and it was shown that 81.4% of parasitized weevils were not paralyzed.
