Predicted distribution of (Tylenchida: Allantonematidae), parasite of the coffee berry borer.

is an endoparasitic nematode of the coffee berry borer . The nematode has only been recorded across a limited geographical range in coffee-growing areas of southeastern Mexico. Because of its confined geographical distribution, the effect of altitude, temperature, and mean annual precipitation on presence/absence in the Soconusco region of Mexico was investigated.

Response of Ferrari (Coleoptera: Curculionidae: Scolytinae) parasitized by the nematode Poinar (Tylenchida: Allantonematidae) to different colors of light.

is a nematode that naturally parasitizes in a coffee-producing region in Chiapas, Mexico. This study investigated changes in the attraction of parasitized borers to light. We compared the attraction of adult females (parasitized and uninfected) to 14 different light wavelengths (350-670 nm) with a control (570 nm, yellow) under laboratory conditions.
