STUDYING THE BIOLOGICAL FEATURES OF DEVELOPMENT AND THE TECHNOLOGY OF BREEDING THE ORIUS LAEVIGATUS FIEB PREDATORY BUGAizhan Mukashevna Chadinova, Abay Orazuly Sagitov, Karlygash Azirbekovna Alpysbayeva and Balzhan Zhasulanovna NaimanovaAbstract Some biological features of development and the technology of mass breeding of the Orius laevigatus predatory bug used in tomato biological protection from thrips have been studied. The indicators of practical importance -the fecundity and the longevity of the entomophage - have been determined. On the Kalanchoe daigremontiana feed substrate, the fecundity of Orius has been on average 39.0 larvae per female vs. 36.4 larvae on the Kalanchoe blossfeldiana feed substrate, and 34.2 larvae on the bean feed substrate. The quantitative yield of adults from the stage of nymphs was determined, depending on the feed type used. On mixed feed, the yield of imago has been 50.8 % vs. 29.3 % on the the eggs of Sitotroga cerealella and 19.9 % on flower pollen. |
