Abstract

Goal. To compare the influence of waste from different entomological industries on the development of the black lionfly. Methods. The experiments were conducted at a temperature of 25.5–26.5 °C and a relative humidity of 55–65%. Wheat bran weighing 100 g was poured with boiling water (180 ml), after cooling it was used to incubate eggs and revive larvae. After reaching 3 mm, they were removed and moved into containers with different types of wet substrate weighing 100 g, 250 pieces each. Repetition 3 times. Biomaterial was inspected daily, moisture and feed were added as needed. To determine the average weight of older larvae, 30 individuals were selected from each garden. They were washed with water and excess substances were removed using filter paper. The arithmetic mean was calculated for each option. The viability of larvae was determined as the ratio of the number of older and initial larvae. Cages with larvae were installed in small trays, where the prepupae were moved. Insects were moved to closed ventilated cages. From each sample, 30 pupae were selected, weighed and the average value was calculated. Pupa viability was determined as the ratio of the number of reborn adults to the number of pupae. The results. The largest mass was found in larvae that developed on the waste of mill fire, a mixture of grain moth waste and mill fire, large wax moth waste and bran (272–293 mg). The viability of larvae was the highest with the combined use of grain moth waste and vegetable mixture — 98%. The highest viability of pupae (96.2%) was observed in the version where waste from the mill fire was used. Conclusions. In general, according to the experiment, the best results were obtained with the use of mill fire waste and grain moth waste together with a vegetable mixture.
