Abstract

— The article presents the results of research on the use of entomophagous and their effectiveness
in managing the amount of sucking pests that cause significant economic damage in greenhouse crops.
According to him, from sucking pests to spiders (Tetranychus urticae Koch), greenhouse algae (Trialeyrodes
vaporariorum West.), Plant lice (Aphis gossypii Glover) species have been identified. Chrysoperla carnea
Step. Showed a biological efficacy of up to 87.2% on day 14 when used in a 1:10 ratio (entomophag:
phytophagous) to control spider mites. 1:20-1:30 The biological efficiency in the ratios was relatively low.
In managing the amount of greenhouse effluent, 1:20 (macrolophus: algae) in the variant used in the ratio on
days 14-21 achieved a high biological efficiency of 64.7-71.5%. Good development of macrolophus
entomophagy (Macrolophus nubilis H.S) was observed in greenhouse conditions (+24 ºC air temperature,
64% relative humidity). In the greenhouse, wild gallitsa is also a wild gallitsa against plant aphids 1:2, 1:5
and 1:10 the highest rate of biological efficiency when applied in proportions 1:2 in the variant used in the
ratio, in which the figure was 47.2 - 80.1%.
