Predation of Ladybird Beetles (Coleoptera: Coccinellidae)
Studies of predation of ladybird beetles (Coccinellidae) have focused on a limited number of predator taxa, such as birds and ants, while other potential predators have received limited attention. I here consider amphibians as predators of ladybirds. Published amphibian gut analyses show that ladybirds are quite often eaten by frogs and toads (Anura), with recorded frequencies reaching up to 15...
متن کاملTemperature-dependent development of Chilocorus bipustulatus (Coleoptera: Coccinellidae).
The effect of temperature on development and survival of Chilocorus bipustulatus L. (Coleoptera: Coccinellidae), a predator of many scale insects, was studied under laboratory conditions. The duration of development of egg, first, second, third, and fourth larval instars, pupa, and preovioposition period at seven constant temperatures (15, 17.5, 20, 25, 30, 32.5, and 35°C) was measured. Develo...
متن کاملTwo new species of the ladybird beetle Hong Ślipiński from Chile (Coleoptera: Coccinellidae: Microweiseinae).
The ladybird beetle genus Hong Ślipiński was previously known from a single female specimen from a subtropical forest in South East Queensland, Australia. Hong guerreroi sp. nov. and H. slipinskii sp. nov. from a temperate forests of Central and Southern Chile are described and illustrated. A key for the species of the genus and complementary characters, including the first description of males...
متن کاملMolecular cytogenetic studies in the ladybird beetle Henosepilachna argus Geoffroy, 1762 (Coleoptera, Coccinellidae, Epilachninae)
The ladybird Henosepilachnaargus Geoffroy, 1762 has been cytogenetically studied. In addition we have conducted a review of chromosome numbers and the chromosomal system of sex determination available in the literature in species belonging to the genus Henosepilachna and in its closely related genus Epilachna. Chromosome number of Henosepilachnaargus was 2n=18, including the sex chromosome pair...
متن کاملA new male-killing parasitism: Spiroplasma bacteria infect the ladybird beetle Anisosticta novemdecimpunctata (Coleoptera: Coccinellidae).
Whilst most animals invest equally in males and females when they reproduce, a variety of vertically transmitted parasites has evolved the ability to distort the offspring sex ratios of their hosts. One such group of parasites are male-killing bacteria. Here we report the discovery of females of the ladybird Anisosticta novemdecimpunctata that produced highly female-biased offspring sex ratios ...
