Abstract
In central Mexico, the center of origin forLeptinotarsa decemlineata (Say) and its principal host plants,L. decemlineata is associated with a diverse complex of natural enemies. Observations during 2 years in Morelos, Mexico revealed 4 species of asopine pentatomids, 7 species of foliar searching carabids, and 2 coccinellids among the predators ofL. decemlineata. Parasitoids include 3 species of tachinids andEdovum puttleri Grissel, an eulophid egg parasitoid. These natural enemies include several predators that have not previously been reported attackingL. decemlineata.
Résumé
Dans la partie centrale du Mexique, zone d'origine deLeptinotarsa decemlineata (SAY) et de ses principales plante hôtes,L. decemlineata y est associé à un complexe d'ennemis naturels. Les obscrvations conduites durant 2 ans dans l'état de Morelos au Mexique révélaient, l'existence de 4 espèces de pentatomides asopine, 7 espèces de Carabes recherchant leurs proies au niveau des feuilles, et 2 Coccinelles parmi les prédateurs deL. decemlineata. Les parasitoïdes comprennent 3 espèces de tachinides etEdovum puttleri, eulophide oophage. Ces ennemis naturels comportent plusierus prédateurs qui n'avaient jamais été mentionnés antérieurement comme attaquantL. decemlineata.
