description Host plant associations of diabroticite beetles were observed under field conditions (June 1 993-August 1 994). Adult insects were sampled in four locations in two climatic zones in the State of Veracruz, México. Incidence of parasitism and predation was recorded. Seventeen species of diabroticites were found. The two climatic zones differed in numbers of species present, Acalymma spp. were exclusively collected from cultivated and wild cucurbits, whereas Diabrotica spp. showed distinct host plant assocíations. The most important factor influencing insect presence and abundance was the phenolotjical stage of the host plant. Flowering stage and number of flowers of cucurbits determined the number of insects and species diversity. The most abundant parasitoid encountered was a tachinid fiy, Celatoria compressa Wulp. Parasitism by nematodes (Mermithidae) and fungi (laboulbeniales) occurred. Predation by several hemipteran species (Reduviidae) and spiders (Oxyipidae) was observed at several occasions.

Acaiynima Diabrotica Celatoria Cucurbitaceae Laboulbenia Mermithidae Acalymma Diabrotica Celatoria Cucurbitaceae laboulbenia Mermithidae Host plant associations of diabroticite beetles were observed under field conditions (June 1 993-August 1 994).

La asociación de diabrolicinas con plantas hopederas fue observada en condiciones de campo (junio 1993 - agosto 1994). los insectos adultos fueron colectados en cuatro localidades de dos zonas climáticas en el estado de Veracruz, México. la incidencia de parasitismo y depredación fue documentada, Diecisiete especies de diabroticina fueron encontradas. las dos zonas climáticas difirieron en el número de especies presentes. las Aca/ymma spp. fueron exclusivamente colectailds de cucurbitáceas silvestres y cultivadas, mientras que las Diabrotica spp. mostraron asociaciones con distintas plantas hospederas. El factor más importante que influyó en la presencia y abundancia de insectos fue el estado fenológico de la planta hospedera. El estado de floración y el número de flores de cucurbitáceas, determinó el número de insectos y la diversidad de especies. El parasitoide más abundante encontrado fue una mosca de la familia Tachinidae, Celatoria compressa Wulp. Se encontró parasitismo por nemátodos (Mermithidae) y hongos (laboulbeniales). Depredación por varias especies de hemópteros (Reduviidaei y arañas (Oxyopidae) fue observada en varias ocasiones. Palabras Clave: Acalymma. Diabrotica, Celatoria, Cucurbitaceae, laboulbenia, Mermithidae.
