Individuals are predicted to behave more altruistically and less competitively toward their
relatives, because they share a relatively high proportion of their genes (eg, one-half for …

M'ale haploidy is a distinctive characteristic of the Hymenoptera and has, important
consequences for sex allocation and social evolution. However, it has been known for over …

This book provides an up-to-date review of the biology of parasitic Hymenoptera, focusing
primarily on genetics, developmental biology, physiology, anatomy and molecular biology …

Recent decades have witnessed an explosion of theoretical and empirical studies of sex
allocation, transforming how we understand the allocation of resources to male and female …

This text provides readers with an in-depth exploration of how biological control functions
and how it can be safely employed to solve pest problems and enhance nature …

The extraordinary taxonomic and morphological diversity of orchids is accompanied by a
remarkable range of pollinators and pollination systems. Sexually deceptive orchids are …

The haplodiploid sex determining mechanism in Hymenoptera (males are haploid, females
are diploid) has played an important role in the evolution of this insect order. In …

▪ Abstract Genetic mechanisms of sex determination are unexpectedly diverse and change
rapidly during evolution. We review the role of genetic conflict as the driving force behind …

It has long been assumed that inbreeding depression in haplodiploid organisms is low due
to their ability to purge genetic load in haploid males. It has been suggested that this low …

We purchased samples of 27 parasitoids, six coccinellid beetles, and the predatory midge
Aphidoletes aphidimyza (Rondani) from commercial insectaries and scored the sex ratios …
