To improve biological pest control, we would like to understand the main factors that limit the reproductive success of key biological control agents, including parasitoid wasps. Previous research with proovigenic parasitoids in the genus Anagrus collected from multiple field sites revealed positive correlations between parasitoid fecundity and local host density. In this article, we test wheth...

Ooctonus Haliday (Hymenoptera: Mymaridae) contains four species in the Neotropical Region: O. clebschi Huber, sp. n., O. costaricensis Huber, sp. n., O. woolleyi Huber, sp. n., and O. zolnerowichi Huber, sp. n.

The estimation of species composition, abundance and biomass cyanobacteria in “bloom” as well the search for toxic has been undertaken first time 20 water bodies courses Belarus mainly used public recreation. There were identified 50 representatives assigned to 18 genera, among them three marked Belarus: Snowella atomus Komárek et Hindák., Anabaenopsis arnoldii Aptekar, kelifii Kog. By combinin...

The corn leafhopper Dalbulus maidis (DeLong) (Hemiptera: Cicadellidae), transmits three important plant pathogens that adversely affect crop and ranges from the USA to Argentina. vector has a rich natural enemy complex generates high levels of parasitism, but its populations are persistent prevalent. We characterized oviposition sites D. on young plants in order verify hypothesis an strategy fo...
