Sažetak
The fumigant efficacy of 1,8-cineole and eugenol compounds was tested on the pupal stage of the red flour beetle Tribolium castaneum (Herbst). Effects of those compounds were determined as mortality as well as impact on development of treated male and female pupae. Also differences in sensitivity to the tested compounds between sexes of T. castaneum pupae were assessed. Compounds were tested at 3 doses rate 0.34, 0.86 and 1.71 ml L-1 vol. at 30±1°C and 70±10% r.h. during 48 h. Compounds toxicity was expressed in two action modes: lethal, and as an impediment to normal metamorphosis of pupae into adult stage, forming "adultoids" and deformed adults (at both sexes). Male pupae were generally more sensitive to both tested compounds. Overall, better efficiency was performed with 1,8-cineole, while eugenol had not accomplished promising effect on the tested pupae.
