Monitoring of oil poppy pests was carried out using visual and modern instrumental methods. In the spring, before soil preparation, soil excavations were carried out in the fields intended for the sowing of oil poppy in order to detect the presence of soil pests. During the research years of 2021-2023, on average, the following soil pests were detected, namely, larvae of ground beetles (II instar) - 1-2 specimens, larvae of woodworms (wireworms) - 2 specimens, larvae of the poppy weevil - 1-2 specimens. Each period of development of oil poppy plants has a peculiar complex of insects that damage it. The most vulnerable period of growing poppies is the seedling phase - the formation of a rosette. In the phase of seedlings - rosettes, the greatest damage is caused by wireworms, larvae of small and sand midges. The aerial part was damaged by the gray beetroot and other weevils, the larvae of the June beetle. During the period of stemming, the harmfulness of khrussa increases. Extremely large damage to poppy crops, namely damage to the underground part during budding - flowering, is caused by the poppy rootworm. Plants withered, their leaves curled, shoots grew and died. One beetle during the day destroys 4-6 poppy plants that are in the germination phase. The presence of 5-6 beetles per linear meter is a threat to sowing. In recent years, there has been a warming of the climate and an increase in the amount of precipitation, as a result of which, sucking pests of leaves (aphids), the root-box nymph or the one-spotted poppy nymph have developed strongly on oil poppy crops. Hidden animals eat generative organs. Larvae and adult insects gnaw buds, eat queens and anthers, puncture crowns, contaminate and eat seeds.  Product Description popup.authors Abramyk Mariia M.
