Abstract

 

Investigations were made from April 2004 to March 2005 in Coimbatore and Theni districts of Tamil Nadu to record the pest status of vanilla and their natural enemies. A total of seven arthropods, seven gastropods and two invertebrates were recorded as pests of vanilla. Out of 60 farms surveyed, only nine had the incidence of pest attack. Among the pests, white grubs and Giant African Snail were found to cause considerable damage to the vanilla plants, while others were not at economic levels. Among the natural enemies, parasitoids like Euplectrus sp.,Glyptapanteles sp., Aprostocetus sp., Chelonus sp., and Uropoda mites were found to be associated with the pests of vanilla.

 

Key words: Vanilla, pests, gastropods, natural enemies
