The chalcid wasp Chouioia cunea Yang (Hymenoptera: Eulophidae) is one of the most dominant pupal parasitoids of Hyphantria cunea (Drury) (Lepidoptera: Arctiidae), an invasive pest of many forestry trees and agricultural crops. For mass rearing C. cunea for biological control purposes, the pupae of Antheraea pernyi (Guérin-Méneville) (Lepidoptera: Saturniidae) have been widely used as a substitu...

Chouioia cunea Yang is an endoparasitic wasp that attacks pupae of Hyphantria cunea (Drury), an invasive moth species that severely damages forests in China. Chemosensory systems of insects are used to detect volatile chemical odors such as female sex pheromones and host plant volatiles. The antennae of parasite wasps are important for host detection and other sensory-mediated behaviors. We ide...

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 ...

Hyphantria cunea (Drury) (Lepidoptera: Arctiidae) is an invasive insect pest which, in China, causes unprecedented damage and economic losses due to its extreme fecundity and wide host range, including forest and shade trees, and even crops. Compared to the better known lepidopteran species which use Type-I pheromones, little is known at the molecular level about the olfactory mechanisms of hos...

Hyphantria cunea (Drury) (Lepidoptera: Arctiidae) is an important forest insect pest around the world. It attacks a variety of broad-leaf trees. It has caused serious economic and ecological damage to its new habitats. A mixture of Bt and chlorbenzuron has a higher toxicity and faster killed than those of either agent alone to the 4th instar larvae of H. cunea both by the lab and field test res...

The fall webworm, Hyphantria cunea (Drury) is a major invasive pest in China. Aminopeptidase N (APN) isoforms in lepidopteran larvae midguts are known for their involvement in the mode of action of insecticidal crystal (Cry) proteins from Bacillus thuringiensis. In the present work, we identified a putative Cry1Ab toxin-binding protein, an APN isoform designated HcAPN3, in the midgut of H. cune...
