Egg parasitism of Trichogramma pretiosum strain RV when presented with eggs of Anticarsia gemmatalis and Pseudoplusia includens was investigated at 18, 20, 22, 25, 28, 30 and 32 C. The number of eggs parasitized per day decreased for both hosts as a function of the age of parasitoids, reaching 80% of lifetime parasitism more rapidly as temperature increased; on the 4th day at 32 C and on the 12th day at 18 C. The lifetime number of parasitized P. includens eggs achieved by the parasitoid maintained at 20 C (44.95 ± 3.94) differed from the results recorded at 32 C (28.5 ± 1.33). Differently, the lifetime number of A. gemmatalis parasitized eggs did not differ among the temperatures. When T. pretiosum reached 100% of lifetime parasitism, each adult female had parasitized from 28.5 ± 1.33 to 44.95 ± 3.94 and from 29.58 ± 2.80 to 45.36 ± 4.50 P. includens and A. gemmatalis eggs, respectively. Also, the longevity of these adult T. pretiosum females, for which P. includens or A. gemmatalis eggs were offered, was inversely correlated with temperature. Not only were the survival curves of those adult T. pretiosum females of type I when they were presented with eggs of A. gemmatalis but also with eggs of P. includens, i.e., there was an increase in the mortality rate with time as the temperature increased. In conclusion, T. pretiosum strain RV parasitism was impacted by temperature when on both host eggs; however, the parasitoid still exhibited high survival and, more importantly, high number of parasitized A. gemmatalis and P. includens eggs even at the extremes tested temperatures of 18 and 32 C. Those results indicate that T. pretiosum strain RV might be well adapted to this studied temperature range and, thus, be potentially suitable for use in biological control programs of P. includens and A. gemmatalis in different geographical areas that fits in this range. It is important to emphasize the results here presented are from laboratory studies and, therefore, field trials still need to be carried out in the future with this strain in order to support the full development of the technology intend to use this egg parasitoid in soybean fields worldwide.

Amancha foliar da gala é uma doença que afeta a macieira durante o período de verão, principalmente os clones da cultivar Gala. Uma vez constatada a doença no pomar esta é de dificil controle devido a velocidade de desenvolvimento e a baixa eficiência dos fungicidas em atuar como curativos. Ademais, a planta pode comportar-se como extremamente suscetível e perder as folhas. A seguir veja as principais características dessa doença. |
