Some Physiological Characteristics of Melon Ladybugs in the Period of Winter Dormancy in Kashkadarya Region

The paper describes that the departure of a melon ladybug for wintering is characterized by the cessation of active nutrition, a  decrease of the water content in the body and the accumulation of fatty substances in the body of beetles. A decrease of the water content in the body of beetles during the winter period is correlatively associated with increasing of hypothermia oftheir body fluids. During the wintering of the melon ladybug, there is a gradual consumption of fat and fat-like substances.The most intensive consumption of fat in beetles is observed in the spring after wintering, during the period of activelocomotor activity. Also, the period of wintering of the melon ladybug is characterized by a decrease in oxygen consumption andinhibition of the entire tissue metabolism.During this period, beetles are in a state of deep dormancy, and are probably the mostresistant to low temperatures in their habitat.
