Tenebrio molitor is one of the main stored product pests. This study characterized oregano essential oil (OEO) by gas chromatography (GC/FID and GC/MS) and assessed its insecticidal properties against T. molitor. Mortality, survival, respiration, and behavioral response in larva, pupa, and adult of this insect were determined. The major components of OEO were carvacrol (25.6%), p-cymene (12.3%), linalool (8.71%), thymol (7.22%), γ-terpinene (7.21%), caryophyllene oxide (4.67%), α-pinene (2.71%), and eucalyptol (2.69%). OEO caused high contact toxicity in larvae (LD50 = 3.03 µg insect–1), pupae (LD50 = 5.01 µg insect–1), and adults (LD50 = 5.12 µg insect−1) of T. molitor. Survival rates were 100% in larvae, pupae, and adults of T. molitor not treated with OEO, declining to 65–54%, 38–44%, 30–23%, and 6–2% in insects treated with LD25, LD50, LD75, and LD90, respectively. Low respiration rates of T. molitor at different developmental stages was observed after OEO exposure. Additionally, OEO exposure affects behavioral avoidance response and causes repellency in larvae and adults. These findings show that OEO exerts insecticidal and repellent effects against T. molitor, suggesting a potent alternative to synthetic insecticides for controlling the beetle.

O gênero Eucalyptus abrange as espécies arbóreas mais utilizadas para reflorestamento no Brasil. Devido ao seu elevado conteúdo de substâncias secundárias, esperava-se que os insetos não causassem sérios danos ao eucalipto. Contudo, muitos insetos, principalmente os da ordem Lepidoptera, tornaram-se sérias pragas na eucaliptocultura. O predador Podisus nigrispinus Dallas (Heteroptera: Pentatomidae) vem sendo utilizado contra insetos herbívoros tais como Thyrinteina arnobia Stoll (Lepidoptera: Geometridae), principal praga do eucalipto, mas não se têm dados sobre seu estabelecimento em áreas de eucalipto. Dessa forma, o objetivo deste trabalho foi avaliar o potencial reprodutivo e sobrevivência de P. nigrispinus sobre T. arnobia proveniente de eucalipto e larvas de Tenebrio molitor L. (Coleoptera: Tenebrionidae) provenientes de criação massal em laboratório. Os aspectos biológicos de P. nigrispinus foram melhores sobre pupas de T. molitor em comparação aos indivíduos criados sobre lagartas de T. arnobia. Provavelmente, as lagartas de T. arnobia estão seqüestrando as substâncias secundárias das plantas de eucalipto e utilizando em sua defesa contra predadores como P. Nigrispinus, e se estes inimigos naturais não estiverem adaptados a tais compostos, a sua performance no controle da praga e no seu próprio desenvolvimento podem ser afetados negativamente.

Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae) is an important pest of stored products. Insecticidal treatment is a common practice for the control of this notorious insect pest. Most studies are focused on the immediate and/or delayed mortality effects, while there are no data on the effects of insecticides on the population fitness. This study deals with the effect of chlorfenapyr on T. castaneum, investigating the cost of exposure of different developmental stages on population performance, by using life table statistics and a survival analysis method. For this purpose, eggs, larvae, and parental adult females of T. castaneum were exposed to chlorfenapyr and birth or death rates were calculated daily. The exposure of eggs and larvae to chlorfenapyr was detrimental for T. castaneum and they did not complete development. When parental females were exposed to chlorfenapyr, the progeny survival curve, biological features, as well as the life table parameters did not differ significantly compared to the control treatment. Thus, egg hatching, larval and pupal developmental periods, female and male longevities for the control treatment, and the progeny of the females that were exposed to chlorfenapyr were 4.66 and 4.76 days, 25.85 and 25.71 days, 5.00 and 5.26 days, 87.33 and 104.22 days, and 76.87 and 91.87 days, respectively. In addition, the mean values of the net reproductive rate, the intrinsic rate of increase, the mean generation time and the doubling time for the control treatment and the progeny of the parental females which were exposed to chlorfenapyr were 14.3 and 9.3 females/female, 0.038 and 0.028 females/female/day, 1.039 and 1.029, 70.0 and 76.9 days, and 18.5 and 24.9 days, respectively. We expect these results to have bearing on the management of T. castaneum, since the repeatedly insecticidal applications could be reduced in storage facilities.
