Improvement of breeding methods of predatory mites Neoseiulus cucumeris and Transeius montdorensis for biological plant protection

The possibility of breeding phytoseiid predatory mites Neoseiulus cucumeris and Transeius montdorensis using hardwood sawdust as a substrate frozen dried fruit mite (Carpoglyphus lactis) feed was studied. number larvae produced by N. 31.5 % lower on in than the control, while T. it 47.7 %. individuals surviving to adulthood compared control 28.6 42.9 %, respectively. maximum daily growth rate population reduced relatively 3.7 cucumeris, 4.5 –. On bran, 20.5 fewer – 35.1 larvae. 18.3 35.3 respectively, control. 1.7 3.9 montdorensis. live sawdust, larval production similar (lower 1.1 14.2 montdorensis). 14.8 is slightly (by 0.7 individuals) even exceeded 0.6 per day. Our results showed cheaper for both species poor performance one.
