Aphid 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 کاملPakistan Entomologist REARING OF COCCINELLA SEPTEMPUNCTATA L. (COLEOPTERA: COCCINELLIDAE) ON NATURAL AND ARTIFICIAL DIETS
Different types of pests are found in nature affecting life and yield of natural and cultivated crops of agro-forestry. Researchers are trying to develop and apply different techniques to control and reduce loss of these pests on agriculture, forest and garden products. Chemical control method (CCM) is frequently applied as it is easy and prompt way to directly kill or repel the pests from crop...
متن کاملIntraguild Predation Behaviour of Ladybirds in Semi-Field Experiments Explains Invasion Success of Harmonia axyridis
Harmonia axyridis has been introduced as a biological control agent in Europe and the USA. Since its introduction, it has established and spread, and it is now regarded as an invasive alien species. It has been suggested that intraguild predation is especially important for the invasion success of H. axyridis. The aim of this study was to compare the intraguild predation behaviour of three lady...
متن کاملMorphology of invasion: body size patterns associated with establishment of Coccinella septempunctata (Coleoptera: Coccinellidae)
The Old World ladybird Coccinella septempunctata has rapidly established itself as an abundant, widespread species throughout North America. Overwintering individuals of this species, and of native ladybirds, were collected from early season alfalfa in northern Utah during the period of initial establishment of the invader (1989 to 1999), and were measured for body size. Adult body size can var...
متن کاملEgg Predation by the Introduced Lady Beetle, Coccinella septempunctata (Coleoptera: Coccinellidae), Lowers Mortality but Raises Relative Risk for the Native Lady Beetle, Coccinella novemnotata
Populations of the native ninespotted lady beetle, Coccinella novemnotata Herbst, have undergone precipitous declines in North America following the establishment of the exotic sevenspotted lady beetle, Coccinella septempunctata L. Recent volunteer efforts have made it possible to establish colonies of the now-rare C. novemnotata and test mechanisms contributing to its decline. We evaluated the...
