MORPHOLOGICAL CHARACTERISTICS AND BIOECOLOGICAL PECULIARITIES OF DEVELOPMENT OF TUTA ABSOLUTA POVOLNY (LEPEDOPTERA:GELECHIIDAE) UNDER LABORATORY CONDITIONS

Аннотация

. The article provides data on the determination of morphological features and bioecological features of
the development of a particularly dangerous object Tuta absoluta (Povlony) in laboratory and greenhouse conditions.
In greenhouses and laboratory conditions, the imago begins to actively mate 3-4 hours before sunrise. In laboratory
conditions, females lay eggs on the surface of leaves (35%), below (45%), stems (15%), fruit leaves (5%), but the
fruit was not laid. After hatching from the eggs, the larvae chew through the entrance to the mesoderm of the leaf and
penetrate for 5 minutes. The Larva Of T. absoluta is almost cylindrical in shape, with a distinct head, three pairs of
pectoral legs, and five pairs of ventral pseudopods. After completing all five stages of development, the larvae
emerge from the mine, and sometimes pupate there. Before pupation, the larva changes its color from dark green to
light green. The pupa of the tomato moth, as in other Lepidoptera, is of the “obtecto " type, that is, with the future
appendages of adults. It has the shape of a cone 4.5-5 mm long and 1.3-1.5 mm wide, greenish in color, turning to a
more intense brown, and at the end of development becomes brown.
In the population, females predominate over males. At a temperature of 15°C and 33°C the ratio of female to
female life expectancy varies. The higher the air temperature, the more females predominate in the population.
