Practical experience of breeding and use of predatory bug Podisus maculiventris in Western Siberia

The predatory bug Podisus maculiventris is a multi-eating entomophages, promising for use in measures the biological protection of potatoes from Colorado potato beetle Western Siberia. In order to reduce economic costs transportation and mass production podizus, it advisable improve adapt technology its breeding conditions region. Under laboratory conditions, effectiveness using different species prey (larvae greater wax moth, diamondback yellow mealworm vetch aphid) maintain high indicators uterine culture was revealed. With mixed diet, survival rate entomophage larvae observed, number images next generation averaged 78.3% initial number, weight females males increased 74.8 56.0 mg, respectively, fertility – 539.6 eggs per 1 female. voracity predator varied on average 1.8 8.4 individuals beetle, depending stage development age pest larvae. As result three-year field trials (2018-2020) Yuna variety, against ranged 66.2 85.4%, with combined preparation Bitoxibacillin 98.5%. 2020, efficiency entomophages at release ratio : 5.0-6.5 varieties 62.9-75.0%.
