In this study, it was tried to determine the amount of prey consumed by Chrysoperla carnea (Stephens) (Neuroptera: Chrysopidae) at varying densities and its potency in reducing population pest. Aphids used as nutrients [Aphis fabae Scopoli Acyrthosiphon pisum Harris (Hemiptera: Aphididae)] were given each larval stage (InstarI, InstarII, InstarIII) predator certain numbers (5, 10, 20, 40, 80, 1...

Çalışmada Düzce ili fındık bahçelerinde zararlı Amerikan beyaz kelebeği Hyphantria cunea (Drury) (Lepidoptera: Arctiidae)’nın ergin popülasyon takibi ile parazitoit ve predatörlerinin belirlenmesi amaçlanmış olup 2019 yılında yürütülmüştür. Ergin Merkez Cumayeri ilçeleri olmak üzere iki farklı lokasyonda belirlenen bahçelere kurulan ışık tuzağı yapılmıştır. Zararlının bireyleri haziran ağustos ...

The prediction of pest-control functioning by multi-predator communities is hindered by the non-additive nature of species functioning. Such non-additivity, commonly termed an emergent multi-predator effect, is known to be affected by elements of the ecological context, such as the structure and composition of vegetation, in addition to the traits of the predators themselves. Here we report mes...
