چکیده
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 in this research work the larval parasitoid complex of grape berry moth (gbm) on vine was identified, and its natural potential in controlling the pest compared for different generations and in different locations in orumieh during 2004-2006. adults of the larval parasitoids of gbm were recorded from laboratory-reared larvae, which had been collected on damaged inflorescences of the first generation and berries of the second and the third generations. rate (%) of parasitism on l. botrana larvae was estimated as the number of parasitoids over the total count of parasitoids and moths. six larval parasitoids of the host were found: enytus apostata gravenhorst, 1829; pristomerus vulnerator (panzer, 1799); temelucha sp. (hymenoptera: ichneumonidae), nemorilla maculosa (meigen, 1824) (diptera: tachinidae), habrobracon hebetor (say) and bracon sp. (hymenoptera: braconidae). total parasitism varied from 1 to 16.8%, with an average of 7.7% as revealed through the present study. a comparison of the means of the larval parasitism rate showed a significant difference at 5% level between different generations and localities. the highest rate of parasitism occurred in the first generation in all localities, as well as in years.

Lobesia botrana (Denis & Schiffermüller, 1775) (Lepidoptera: Tortricidae) is one of the most destructive pests of grape in the Palearctic region. The potential geographical distribution of this pest is important to agriculture security. In this study, Maxent and ArcGIS were used to project the potential geographical distribution of L. botrana in China under the current climate. The result indic...
متن کاملLobesia botrana Larvae Develop Faster in the Presence of Parasitoids
To combat parasitism hosts often rely on their immune system, which is the last line of defense. However, the immune system may not always be effective, and other non-immunological defenses might be favored to reduce the cost of parasite infection. Here we report that larvae of the moth Lobesia botrana can rapidly accelerate their development and reach maturity earlier in response to cues perce...
