This review surveys the literature dealing with food relationships of coccidophagous,
aleurodophagous and psyllophagous coccinellids. While in the cold temperate climate …

This review is discussed under the following headings: the criteria for establishing the
existence of cytoplasmic sex ratio distorters; the incidences and mechanisms of cytoplasmic …

Food relationships of Coccinellidae have always been actively studied, largely because of
the economic impact of most coccinellid species. Unfortunately the prey-predator …

The chapters of this book are entitled: the evolution of heritable symbionts; cytoplasmic
incompatibility in insects; inherited microorganisms and sex determination of arthropod …

Life tables for two predatory ladybirds, Coccinella septempunctata andHarmonia axyridis,
were constructed in two years in which prey abundance differed. The prey aphid, Aphis …

Maternally-inherited male killing microorganisms are known in a number of insect species.
We here discuss the evolutionary reasons for such behaviour through examining the …

We investigated the consequences of cannibalism for some correlates of fitness in the fall
armyworm, Spodoptera frugiperda (Lepidoptera: Noctuidae). The benefits gained by …

Entomophagous lady beetles often prey on a variety of insects in addition to the Hemiptera
(Sternorrhyncha) for which they are well-known natural enemies. Many species (particularly …

Cannibalism, a widespread phenomenon in nature, can both reduce competitors and
introduce a high-quality food into the cannibal's diet. We investigated the dietary benefits of …

The relative impact of cannibalism and predation on the development and survival of fourth
instar larvae was assessed in two species of aphidophagous ladybird beetles, Coccinella …
