Влияние смены кормового растения на рост и выживаемость гусениц шелкопрядов (Antheraea pernyi G.-M., Lymantria dispar L., Endromis versicolora L.)

Abstract

Переход дубового, непарного и березового шелкопрядов с дуба на иву и черемуху приводит к меньшим потерям гусениц, чем переход гусениц с березы на эти же породы = Moving of oak, non pair and birch silkworm from oak onto willow and bird cherry results in fewer losses of caterpillars than moving of caterpillars from birch onto the same trees, Efficiency of nitrogen and energy balance reduces compared to the control group of olygophagus caterpillars – of birch and oak silkworm when moving from oak on bird cherry and willow to a smaller degree than when moving from birch onto willow and bird cherry. These parameters of polyphagus caterpillars, non pair silkworm, have a slight tendency to reduce on new fodder compared to the control and olygophagus. Thus, energy of food, survival and intensity of insect growth, with the change of fodder plant, depend not only on the type of new fodder but also on food specialization of insects, peculiarities of the previous fodder.
