Protein synthesis in developing ovaries of mealworm under in vivo and in vitro conditions: Effects of diflubenzuron

1996

Abstract The effect of diflubenzuron (DFB) on protein synthesis in the ovaries of Tenebrio molitor was evaluated during oocyte maturation using in vivo and in vitro assays. When incorporated into the diet (5 and 10 mg g −1 ), DFB was found to affect both the weight, the protein levels and the incorporation of tritiated leucine into proteins of ovaries. In addition, electrophoretic separation of ovarian proteins by sodium dodecyl sulfate-polyacrylamide slab gels (SDS-PAGE) showed that DFB applied in vivo did not have a significant effect on the number of protein bands. When added to the culture medium (5 and 10 μg ml −1 ), DFB resulted in a slight but significant decrease in the rate of inco…

Sex pheromone identified after solid phase microextraction from tergal glands of female alates in Cornitermes bequaerti (Isoptera, Nasutitermitinae)

2002

For the first time, a termite sex pheromone secreted by tergal glands has been isolated and identified. In the mandibulate nasute termite Cornitermes bequaerti, pairing of swarming imagoes is mediated by a sex pheromone secreted by females from their tergal glands. These well developed sexual glands located in front of tergites 8, 9, 10 are essentially composed of class 1 and 2 cells, but also of some glandular units of class 3 cells. The major volatile compound of tergal secretion was isolated by solid phase microextraction (SPME) and identified by GC-MS as (3Z, 6Z, 8E)-dodecatrien-1-ol. Sex attraction bioassays with synthetic (3Z, 6Z, 8E)-dodecatrien-1-ol showed that this alcohol was the …
