A study was conducted in the Biocontrol Laboratory, Department of Entomology, College Agriculture, OUAT, Bhubaneswar, Odisha during 2020-21 to record influence larval diets on pupal period and size cocoon Chrysoperla zastrowi sillemi (Esben-Peterson). Six i.e. T1 (Purple aphid, Aphis craccivora Koch.), T2 (Green Myzus persicae (Sulzer)), T3 (Mustard Lipaphis erysimi (Kalt.)), T4 (Papaya mealy b...

Imidacloprid-induced hormesis in the form of stimulated reproduction has previously been reported in green peach aphid, Myzus persicae. Changes in gene expression accompanying this hormetic response have not been previously investigated. In this study, expression of stress response (Hsp60), dispersal (OSD, TOL and ANT), and developmental (FPPS I) genes were examined for two generations during i...

Several Ascomycetes fungi are commonly used in bio-industries and provide available industrial residues for lectin extraction to be valuable. A lectin from Penicillium chrysogenum, named PeCL, was purified from a fungal culture using gel-filtration chromatography column. PeCL was found to be a mannose-specific lectin by haemagglutination activity towards rabbit erythrocyte cells and was visuali...

In 1990 and 1991, populations of the cabbage aphid, Brevicoryne brassicae, and the green peach aphid, Myzus persicae, were monitored on broccoli interplanted with three leguminous cover crops (the living mulches) and compared with broccoli without cover crop (clean cultivation). The cover crops used were white clover ( Trifolium repens L.), strawberry clover (Trifolium fragiferum L.) and a mixt...

BACKGROUND Biotic stress induced by various herbivores and pathogens invokes plant responses involving different defense mechanisms. However, we do not know whether different biotic stresses share a common response or which signaling pathways are involved in responses to different biotic stresses. We investigated the common and specific responses of Arabidopsis thaliana to three biotic stress a...

Host plant diversity causes differences in the biology and adaptation of insects. In this study, variations some biological properties adaptive antioxidative response Myzus persicae (Sulzer,1776) (Hemiptera: Aphididae) on five Charleston pepper, Capsicum annuum L. (Solanaceae) cultivars were investigated under laboratory conditions (25±1°C, 60±5% RH). The lowest intrinsic rate increase (r = 0.1...

the prey suitability for generalist predators is an important feature for efficient mass rearing and ipm. the green lacewing, chrysoperla carnea (stephens) is a polyphagous predator attacking several pests on various crops. this experiment was conducted under laboratory conditions at 25 ± 2 °c, 60 ± 5% r. h. and a photoperiod of 16l: 8d h. the effects of different prey species were investigated...

Myzus persicae is an economically important pest infecting more than 40 families of crops throughout the world. Six entomopathogenic fungal isolates, three each of Beauveria bassiana and Verticillium lecanii, were screened for pathogenicity test against the M. persicae to select high virulent isolate with the most suitable application and to determine the role of individual enzyme in its virule...
