Diapause in insects occurs in response to environmental cues, such as changes in photoperiod, and it is a major adaptation by which insects synchronize their activity with biotic resources and environmental constraints. For multivoltine agricultural insect pests, diapause initiation is an important consideration in management decisions, particularly toward the end of the growing season. The gra...

The grape berry moth, Paralobesia viteana Clemens (Lepidoptera: Tortricidae), is a key economic pest of vineyards in eastern North America, and prevention of fruit infestation is particularly challenging along vineyard borders that are adjacent to wooded areas containing wild grape (Vitis spp.). For three years, infestation and damage in vineyards where reduced-risk insecticides were applied to...

in 2005, during a survey on the biology of grape berry moth, lobesia botrana (denis & schiffermã¼ller) in nazlochay of urmia region, some damaged symptoms of another moth on the berries of grape were observed that caused by a coleophorid species determined as coleophora hemerobiella (scopoli). this species, which is newly reported from iran, also may be considered as a new pest of vineyards of ...

grape berry moth, lobesia botrana (denis and schiff.) is a destructive pest of grapevine in orumieh (northwest, iran) vineyards. it is mainly controled through application of broad-spectrum insecticides, which can adversely affect vineyard ecosystem and consequently human health. since a first step in setting up an ipm program is to assess the biological control agents within the ecosystem, so ...

The grape berry moth, Paralobesia viteana (Clemens), is a key pest of vineyards in eastern North America that overwinters as pupae in leaf litter on the vineyard floor. This presents an opportunity for tillage to disturb and bury the pupae, providing a potential nonchemical approach to control of this pest. Using a Lilleston-style rotary cultivator, we determined the distribution of pupae withi...
