May Bugs — intensifyed flash of reproduction
Abstract
The retrospective analysis of the long-term dynamics of the populations of the Scarabaeidae family has shown an increase in the numbers of may bugs (Melolontha melolontha L. and M. hippocastani F.). The development of western may bugs is more closely connected with forest band and cultivated land, while the eastern related with forest plantations and meadows. The increase in the number of may bugs, which lasts for the last 15 years (2001—2015) is due to the warming of the climate and the decrease in the death of the wintering stages, the easing of the struggle against the imago during their period (the absence of sprinkling of forest bands), the simplification of the system of basic land cultivation, intensive forests hacking and improved development conditions of the eastern may bugs. The observation the population development and targeted control measures should be intensified in the period of increasing the number and flash of reproduction of these dangerous polyphages which both in the stage of the beetle and the larvae make a damage. The forest strips with deciduous breeds should be sprayed over with insecticides based on alpha-cypermethrin against the imago of ≥50 beetles / wood. Taking into account the high level of fields population of may bug’s larva and other soil pests, the seeds should be seeded with insecto-fungicidal pesticides based on beta-diglytrin, bifetrin, clothianidine, imidiocloprid, tefluthrin, thiamethoxam and combinations thereof.
