بررسی کارایی سه نوع پروتئین هیدرولیزات در جلب و شکار مگس میوه زیتون Bactrocera oleae توسط تله های مکفیل

Olive fruit fly, Bactrocera oleae, is one of the main pests threatening commercial olive (Olea europaea) worldwide. So far, various strategies have been utilized to control this pest. Nowadays, some hydrolyzate proteins as attractive and deadly prey for insects in traps have considerably attracted the gardener's attention. In this study, the effects of three proteins from different companies, including Ceratrap, Biosber, and Seratel, in three concentrations (2%, 3%, and 4%), with deltamethrin toxin at a concentration of 1:1000 in McPhail traps were evaluated to attract olive flies. The obtained results showed that the rate of protein attracting in early June was highly low. On the other hand, the attracting rate of olive flies was significantly increased in November. The Ceratrap demonstrated better results as compared to other proteins in trapping flies. However, the function of the Seratel at 3% concentration considerably improved at the end of the experiment. In addition, increasing the concentration to more than 3% had no positive effects on the protein's efficiency. Therefore, it seems that a concentration of 3% is optimal for all three studied proteins. Moreover, analyzing the Chrysoperla carnea indicated that the Ceratrap protein at 4% concentration increasingly attracts this beneficial insect in summer. There was no significant difference between treatments in autumn. Altogether, the findings presented here strongly indicate hydrolyzate proteins' positive results as biological controllers over chemical control.
