  abstract = {{T}he western flower thrips, {F}rankliniella occidentalis ({P}ergande) ({T}hysanoptera: {T}hripidae), is a key pest of sweet pepper cultivation, where it causes feeding damage, excretes phytotoxic substances, and transmits important viruses. {C}ontrol with chemical insecticides often is ineffective because endophytic oviposition and the cryptic habits of the pest provide protection. {I}n {U}ruguay, the biological control program of this pest in sweet pepper crops is at risk due to the low settlement rate and high dispersal of releases of predator {O}rius insidiosus ({S}ay) ({H}emiptera: {A}nthocoridae). {P}revious studies have ruled out an antibiosis effect as the cause of dispersal; therefore, we hypothesized antixenosis (non-preference) for the sweet pepper plants as the cause of poor biological control by {O}. insidiosus. {T}he effect of olfactory stimuli from different structures of strawberry, corn, and sweet pepper plants (lamuyo and blocky type) on the behavior of {O}. insidiosus was evaluated in olfactometry and free-choice cage experiments. {S}ince {O}rius tristicolor ({W}hite) ({H}emiptera: {A}nthocoridae) occurs naturally in the area, it was included also in the study with the aim of assessing whether there are differences in behavior between the species. {O}rius tristicolor may act as a complementary biocontrol agent or competitor on sweet pepper. {Y}-tube experiments showed no preference for plant volatiles in any combination, and response to volatile stimuli generally was poor. {H}owever, in the free-choice cage experiment, females of both species of {O}rius preferred the flowering strawberry plants over the flowering sweet pepper plants, which could explain the low establishment of {O}. insidiosus when released on pepper with neighboring strawberry fields. {G}iven that horticultural greenhouses in {U}ruguay and in many other countries are open, this information can be very useful in designing the spatial and temporal management of different crops on a production field, which enhances the effectiveness of these predatory species.},
