Abstract The carnation tortrix moth, Cacoecimorpha pronubana , and the light brown apple Epiphyas postvittana (Walker, 1863) (Lepidoptera: Tortricidae) are two important polyphagous pest species affecting a wide range of plant many which horticultural crops. Crop damage is caused by larvae these moths rolling leaves together feeding on foliage. In order to understand how affected host through t...

A rapid and sensitive extractive spectrophotometric method has been developed for the determination of samarium using 0.04% Chlorophosphonazo III in 1 mol L hydrochloric acid media after extraction into isoamylalcohol. Absorbance was measured in 1-cm cell and the complex has a sensitive absorption peak at 667 nm. The complex of Sm(III)-Chlorophosphonazo III is formed instantly in organic phase ...

Population cycles have fascinated ecologists since the early nineteenth century, and the dynamics of insect populations have been central to understanding the intrinsic and extrinsic biological processes responsible for these cycles. We analyzed an extraordinary long-term data set (every 5 days for 48 years) of a tea tortrix moth (Adoxophyes honmai) that exhibits two dominant cycles: an annual ...
