lethal and sublethal effects of abamectin and deltamethrin on potato tuber moth, phthorimaea operculella (lepidoptera: gelechiidae)
the potato tuber moth (ptm), phthorimaea operculella (zeller) is one of the important pests of potato in tropical regions. in this research, the toxicity of two insecticides, abamectin and deltamethrin on p. operculella was studied at 26 ± 1 c°, 65 ± 5% rh and photoperiod of 16:8 h (l: d). the concentrations were determined by preliminary dose setting experiments. distilled water was used as co...
متن کاملDisruption of Phthorimaea operculella (Lepidoptera: Gelechiidae) oviposition by the application of host plant volatiles
BACKGROUND Phthorimaea operculella is a key pest of potato. The authors characterised the P. operculella olfactory system, selected the most bioactive host plant volatiles and evaluated their potential application in pest management. The electrophysiological responses of olfactory receptor neurons (ORNs) housed in long sensilla trichodea of P. operculella to plant volatiles and the two main sex...

15 صفحه اولPopulation biology of the potato tuber moth, Phthorimaea operculella (Lepidoptera: Gelechiidae), in two potato cropping systems in Israel.
The life cycle, within-field distribution, crop damage and impact of natural enemies of the potato tuber moth, Phthorimaea operculella (Zeller) were investigated in two potato cropping systems. The two systems differed in soil type (sandy vs. loess) which in turn affected the choice of cultivars, irrigation programme, insecticide application method (ground vs. aerial), and planting and harvest ...
