- There is a lack of available literature and sources on the melon fly. Since the bioecological properties and harm of this pest have not been fully studied, the development of effective measures to combat it is difficult, - says Burkhan Fayzullaev, Associate Professor of the Department of Ecology and Life Safety of SamSU. - During 2017-2018 we conducted research in the melon-growing farms of the Urgut district of the Samarkand region to study the distribution and bioecological characteristics of the melon fly in the agrocenosis of melons. The melon fly is the worst pest of gourds on earth, and also surpasses other animals in zoogeographic distribution.

    An adult fly has a yellow or light golden hue, two distinct paths pass along its chest. There are seven different figured dark dots on the shoulder. On the wings there are three yellow transverse stripes that are literal in shape. In fact, the Latin name of the melon fly, Myopardalis pardalina, is given because the striped yellow stripes on its body resemble leopard ones. The thighs of the hind limbs are somewhat thicker. The size of the male is 5-6 mm. comes. The female has chitinized egg sacs at the end of the abdomen, in which she lays her eggs, freely piercing the young melon fruit.

    From the observations made, it is known that one fly lays up to 110 - 153 eggs. As the melon gets bigger and the cork thickens, the mosquito does not lay eggs in it, as the larvae from the eggs cannot get inside by piercing the thick bark.

    Fly eggs are oblong white, 1 mm long, in the form of cones when viewed through binoculars. comes. Special ribs on the egg are clearly not visible, the eggs have a certain degree of viscosity. After 2-5 days, larvae hatch from the laid eggs, which feed on melon bones and move to the seeds.

    The worm is white, slowly thickening from the anterior end of the body to the posterior end. The rear end of its belly was carved in a vertical position. There are two spines at the ends of the last segment. Worm length 1cm comes.

    False cocoon-chitinized, oblong-oval, yellow-brown, 0.7-0.8 mm long. comes. In autumn, the insect goes through the wintering stage in 10-15 cm of soil. grows deep. Basically, it is observed that 2-3 generations of fly worms go further for wintering, surrounding a false cocoon. In the spring, flies fly out of 30% of these hummingbirds.
