Influence of sowing terms on damages of a soybean caused by acacia pickleworm (Etiella zinckenella TR.) and cotton noctuid (Helicoverpa armigera HB.)

Data of researches on influence of different sowing terms of soybean cultivars on plant damages caused by acacia pickle-worm (etiella zinckenella tr.) and cotton noctuid (helicoverpa armigera hb.) are resulted. The investigation showed, that damages of soybean pods by phytophagans depended on sowing terms and was connected with phonological features of cultivars and studied pests. All studied cultivars were damaged lower when sowed early (10-20 of April) in comparison with cultivars sowed later (after 20 of May).
