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...

Maize (Zea mays) pollen is highly nutritious and can be used by predatory arthropods to supplement or replace a carnivorous diet. We demonstrate that maize pollen can be utilized by larvae of the green lacewing, Chrysoperla carnea (Neuroptera: Chrysopidae) under laboratory conditions. Complete development on maize pollen was not possible, but 25% of neonates reached the third instar. When only ...

Abstract For herbivorous insects, dropping from the host plant is a commonly-observed antipredator defence. The use of compared to other behaviours and its timing in relation contact with predator was explored both pea aphids ( Acyrthosiphon pisum ) potato Macrosiphum euphorbiae ). Pea dropped more frequently response ladybird adults Adalia bipunctata than lacewing larvae Chrysoperla carnea Pot...
