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 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 کاملDevelopment and characterization of nine polymorphic microsatellite markers in the seven-spotted lady beetle, Coccinella septempunctata (Coleoptera: Coccinellidae)
In this study, nine microsatellite loci were isolated and characterized from the seven-spotted lady beetle, Coccinella septempunctata (Coleoptera: Coccinellidae). The loci were validated and characterized using 20 samples collected from five Korean localities. These results indicate that some loci were highly variable in terms of number of alleles (2 to 13), heterozygosity (0.10 to 0.40), and p...
متن کاملTRANSGENIC PLANTS & INSECTS Development of an Early-Tier Laboratory Bioassay for Assessing the Impact of Orally-Active Insecticidal Compounds on Larvae of Coccinella septempunctata (Coleoptera: Coccinellidae)
Early-tier studies are the initial step in the environmental risk assessment of genetically engineered plants on nontarget arthropods. They are conducted in the laboratory where surrogate species are exposed to higher concentrations of the arthropod-active compound than those expected to occur in the Þeld. Thus, early-tier tests provide robust data and allow to make general conclusions about th...
