The effects of á-tocopherol and ternatin on the morphology, activation, and growth of goat preantral follicles in vitro cultured, for one or five days, were evaluated. Ovarian fragments were immediately fixed (non-cultured control) or in vitro cultured for one or five days in Minimum Essential Medium (MEM) with or without á-tocopherol or ternatin supplementation, both at concentrations of 5, 10, or 15ìM, corresponding to the following treatments: MEM, TOC5, TOC10, TOC 15, TER5, TER10, and TER15. The percentages of morphologically normal preantral follicles in non-cultured ovarian tissue (control) was 73.2% and after five days of culture, there was a decrease on these percentages in all treatments (P<0.05) when compared with non-cultured control. Culture of ovarian cortex for five days increased the percentages of follicular activation in all treatments (P<0.05). Ultrastructural analysis did not confirm the integrity of caprine preantral follicles cultured for five days in medium containing antioxidants. This study demonstrated that á-tocopherol and ternatin can promote follicular activation; however, addition of these antioxidants in the tested concentrations reduced the follicular viability after in vitro culture. |

Chrysodeixis includens (Walker 1858), also known as soybean looper, is a polyphagous pest with increasing economic significance in various crops. The rate of infestation and its distribution can be in fluenced by feeding through direct and indirect effects on their life cycles. Thus, this study aimed to examine the biological character-istics, food preference and leaf consumption of C.includens on soybean (BRS 284), cotton (FMT 701), sun flower (BRS 323) and common morning glory leaves (Ipomoea sp.) as possible host plants. The experiments were conducted with specimens obtained from mass rearing in the laboratory.C. includens larval and larval-adult stages were shorter in sun flower and longer in cotton. Also, larval preference was greater for sun flower and lower for cotton leaves. Soybean leaves were consumed the least in contrast to sun flower and common morning glory leaves, which were consumed the most. These results suggest that soybean, sun fl ower or common morning glory leaves were favourable hosts for C. includens development, whereas cotton leaves are less nutritionally adequate for insect development. In addition, sun flower leaves reduce C. includens development time and promotes a survival rate greater than 95%, and the leaves are more attractive to larvae when compared with the other tested hosts. This indicates sun flower is the most favourable host among the tested plants for C. includens. |
