Impact of Ambient Humidity on Traction Forces in Ladybird Beetles (Coccinella septempunctata)
Many insects possess hairy adhesive foot pads, supplemented with a tarsal secretion, which allow them to securely and reversibly attach to various kinds of natural substrates, also under complex environmental conditions. Conditions such as ambient temperature and humidity have been shown to influence the attachment ability of the dry adhesive foot pads in spiders and geckos. For insects, howeve...
متن کاملInfluence of ambient humidity on the attachment ability of ladybird beetles (Coccinella septempunctata)
Many insects possess adhesive foot pads, which enable them to scale smooth vertical surfaces. The function of these organs may be highly affected by environmental conditions. Ladybird beetles (Coccinellidae) possess dense tarsal soles of tenent setae, supplemented with an adhesive fluid. We studied the attachment ability of the seven-spotted ladybird beetle (Coccinella septempunctata) at differ...
متن کاملAphid Species Affect Foraging Behavior of Coccinella septempunctata (Coccinellidae: Coleoptera).
BACKGROUND Flowers are admirable in scenic good looks and artistic beautification. These are also playing necessary roles in therapeutic preparations. Aphid is an important sucking pest of various flowers in ornamental territories and it is generally controlled by predators, so it was necessary to evaluate which aphid species affect the predator more or less. MATERIALS AND METHODS Biocontrol ...
متن کامل: metadiscourse in introduction sections of applied linguistics and physics research articles: exploring variation in frequency and type
abstract in written mode of language, metadiscourse markers are used commonly to help writers in general and academic writers in particular to produce coherent and professional texts. the purpose of the present study was to compare introduction sections of applied linguistics and physics articles regarding their use of interactive and interactional metadiscourse markers based on the model pro...
15 صفحه اولPredation 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...
