Bacteria in ovarioles of females from maleless families of ladybird beetles Adalia bipunctata L. (Coleoptera: Coccinellidae) naturally infected with Rickettsia, Wolbachia, and Spiroplasma.
Ovarioles were found to be infected with Spiroplasma, Wolbachia, and Rickettsia in Adalia bipunctata females with maleless progeny in different natural populations. Ooplasm was infected with few Wolbachia bacteria. In ooplasm infected by Rickettsia, bacteria were present in small foci. Spiroplasmas were found encapsulated into ooplasm from the wider intercellular spaces between epithelial and o...
متن کاملچند ریختی کفشدوزک Adalia bipunctata (Coleoptera: Coccinellidae) روی درختان پسته اهلی و وحشی در استان کرمان
کفشدوزک دو نقطه‌ای L. Adalia bipunctata، در الگوی رنگی بالپوش و پیش گرده دارای چند ریختی است. در تحقیق حاضر چند ریختی الگوی رنگی بالپوش‌ها در‌این کفشدوزک روی درختان پسته اهلی (Pistacia vera L.) و وحشی (Pistacia atlantica subsp. mutica F.&M.)در استان کرمان در سال‌های 1388-1389 مطالعه شد. نمونه‌ها با روش ضربه زنی جمع آوری شدند و با استفاده از کلید‌های موجود و معتبر بر اساس اندام جنسی و ویژگی‌های...
متن کاملPredation 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 کاملIncidence of male-killing Rickettsia spp. (alpha-proteobacteria) in the ten-spot ladybird beetle Adalia decempunctata L. (Coleoptera: Coccinellidae).
The diversity of endosymbiotic bacteria that kill male host offspring during embryogenesis and their frequencies in certain groups of host taxa suggest that the evolution of male killing and the subsequent spread of male-killing symbionts are primarily determined by host life history characteristics. We studied the 10-spot ladybird beetle, Adalia decempunctata L. (Coleoptera: Coccinellidae), in...
متن کاملRickettsial relative associated with male killing in the ladybird beetle (Adalia bipunctata).
A cytoplasmically inherited microorganism associated with male killing in the two-spot ladybird beetle, Adalia bipunctata, is shown to be closely related to bacteria in the genus Rickettsia. Sequencing of a PCR-amplified product of the 16S genes coding for rRNA (16S rDNA) shows the organism associated with male killing in ladybirds to share a common ancestry with the Rickettsias relative to oth...
