Considering the importance of Euschistus heros a soybean pest and the high incidence of the parasitoid Hexacladia smithii on this host, its influence on the survival and reproductive potential was evaluated. These two factors were compared under laboratory conditions (25C+2C, 65%+10% RH, 14L:10D) using healthy and parasitized females at different development stages (1,7 and 14 days of adult life). A strong influence of H. smithii parasitism on the reproductive capacity of E. heros females at the different ages studied was detected. Fecundity was drasticaly reduced when the parasitism occurred at the first day female adult life, when they are reproductively imature. During ca. 46 days, healthy E. heros females deposited an average of 66.92 eggs, (11.31 eggs masses/female), statistically higher than the values obtained for females parasitized by H. smithii at 1,7 and 14 days of adult life, when average values of 1,8.86 and 14.10 eggs per female, respectively. In relation to egg masses size there was significant differences among treatments. Althoug data had shown a tendency for bigger egg masses (5.71 eggs) for healthy females as compared to H. smithii parasitized females (1 to 4.24 eggs/egg mass). E. heros egg fertility was not affected by H. smithii parasitism when this occurred at seven (60.41%) and 14 days of adult life (71.40%) as compared to healthy females (94.22%). Parasitism supressed adult survival after 45 days, compared to 32% survival of unparasitized ones. These results indicate that parasitism by H. snithii affected the reproductive capacity of E. heros in all stages tested being its influence higher when the insect was immature (1 day) reducing the offsprings and causing high mortality to the host.

Abstract: Plant essential oils have been recognized as important natural resources for prospecting new biopesticides. Piper aduncum, an abundant plant in the Amazon region, displays insecticidal and fungicidal properties. In this study, nanoformulations containing the essential oil of Piper aduncum were prepared using two protocols: poly (ɛ- caprolactone) (PCL) containing Tween 80 as a stabilizer, and Zein protein using Pluronic (poloxamer) copolymer as a stabilizer. The PCL encapsulation approach proved to be a successful strategy for use as a nanocarrier of active compounds for agricultural applications. It can contribute to more effective and environmentally friendly pest management in agricultural systems. |
