Semelparity and the evolution of maternal care in insects
Article Abstract:
It is difficult to predict maternal care among insects since a number of factors have shaped its development. Maternal care may involve low costs, as in the case of the horsefly. Some insects can breed more than once in a season, and these insects have more to lose by investing in maternal care, since the number of offspring that they can produce is limited. Mothers have greater freedom to invest in offspring if this does not prevent them from breeding again.

Chemical mediation of egg dumping in the lace bug Gargaphia solani Heidemann
Article Abstract:
A study was conducted to examine whether a chemical deposited by the female lace bug, Gargaphia solani Heidemann, during or shortly after oviposition is a signal for egg dumping. Results showed that egg dumping was more frequent when exposed to chemical extracts from young egg masses and was not stimulated by visual cues. Moreover, the ovipositional chemical used by egg-dumpers is not a way of relocating their eggs.

The effect of relatedness on Gargaphia egg dumping behaviour
Article Abstract:
A study of egg dumping behavior in the lace bug, Gargaphia solani, and the effect of relatedness in the females, shows that dumpers are usually unrelated to recipients under natural conditions. Also, the lace bugs are not discriminatory in their behavior toward unrelated egg dumpers. The recipients provide protection to their own centrally located eggs by receiving a large number of dumpers eggs.
