Description:	The aim of this experiment was to compare the effectiveness of emulsifiable oil fungal formulations to a standard water plus Tween 80 and to Peanut oil at different doses of Metarhizium anisopliae conidia and to observe if the emulsifiable oil content can enhance the performance of fungal conidia on Tenebrio molitor (Coleoptera: Tenebrionidae) larvae. Conidial suspensions were formulated in: water plus 10% Codacide (rapeseed oil with emulsifiers); water plus 10% Natur'l oil (rapeseed oil with emulsifiers); water plus 0.05% Tween 80 (laboratory wetting agent); peanut oil (vegetable oil). All formulations were tested at 5 different doses (0, 10², 10³, 10 4, and 10 5 conidia/insect). The inoculated larvae were incubated at 25±0.5 ºC and 24 darkhours. The average survival time for each treatment and a Log Rank statistic for significance were obtained by Kaplan-Meier Survival Analysis and the estimated LD 50 and LD 95 of each formulation was obtained by Probit Analysis with Iogit-transformed values. Emulsifiable oil fungal formulations with 10% Codacide or 10% Natur'l oil have worked as well as peanut oil. Appropriate emulsifiable oils have a great potential for mycoinsecticide formulations because they can combine the infectivity of oil based formulations with the cost effectiveness and versatility of the use of water.
