Abstract

The preference of Trichogramma cacoeciae Marchal for four hosts (Lobesia botrana Den. y Schiff., Ephestia kuehniella Zeller, Spodoptera exigua Hübner and Plodia interpunctella Hübner) was evaluated using no choice, paired-choice and multiple choice assays. The number of adults produced (in absolute or percentage terms) and the sex proportion of said progeny were used to measure preference. T. cacoeciae parasitized and developed in all four hosts. In general, E. kuehniella was the most parasitized species. On the contrary, S. exigua was the least attacked species. Sex ratio remained the same in all cases, thus rendering it useless as a measure of preference.
