the effect of temperature on demographic parameters of the greater wax moth, galleria mellonella (l.) was studied at 23, 25, 27, and 30 °c, 50 ± 10% rh and a photoperiod of 16:8 (l: d) h. the life table parameters were estimated according to the age-stage, two-sex life table procedure. in addition, the bootstrap technique was employed for estimating the means, variances, and standard errors of ...

introduction: macrosiphum rosae is one of the most important members of the aphididae (hemiptera) which feeds on plant juices, colonizes underside of leaves,stems and buds. this pest is a polyphagous insect vastly found in europe, asia and america. coccinella septempunctata (l.) (col: coccinellidae) is the successful biological control agent against aphids in under the greenhouse and field cond...

demographic parameters of the pink stem borer, sesamia creticalederer (lepidoptera: noctuidae) were estimatedon its two main host plants, maize and sugarcane. the present studywas conducted under laboratory conditions at 27±1˚c, 50±10% relative humidity (rh %), and a photoperiod of 0:24 (l:d) hour for the larval stage and 16:8 (l:d) hour for the other life stages. the raw data were analyzed bas...

OBJECTIVE This report presents revised rates of reproduction for 1990-93, reproduction rates for 1994-2002, and intrinsic rates for 2000-2001. The revised rates for 1991-93 are based on populations consistent with the April 1, 2000, census, as are the rates for 1994-2002. METHODS Tabular and graphic data on the reproduction and intrinsic rates by race and Hispanic origin of mother are present...

increased nitrogen applications to crops influence plant-herbivore interactions and potentially increase herbivore population growth.in this research, the impact of nitrogen fertilizations on nutritional quality of three canola (brassica napus l.) cultivars (zarfam, okapi and modena), and, consequently, the performance of mustard aphids, lipaphis erysimi kalt., on them were investigated under g...
