... of biosynthesis (especially oogenesis in females) drive elevated resource acquisition requirements and confer vulnerability to imbalanced diets. Nutrient targets and allocation into key tissues associated with life history investments were determined for juvenile and adult male and female field crickets ( Gryllus...

...-zygotic development at which a thermal cue was provided. Measurements were taken on adult offspring acclimated to 18 or 30°C, produced by mothers previously reared at 24°C and then exposed to 18 or 30°C at an early and late stage of oogenesis. When the shift from 24°C was provided early during oogenesis...

..., but little is known about them in insects. Our purpose was to explore the occurrence of AQPs in the ovary of the phylogenetically basal insect Blattella germanica (L.) and to study their possible role in fluid homeostasis during oogenesis. We isolated an ovarian AQP from B. germanica (BgAQP) that has...

... metabolic rate muscle performance oogenesis alternative splicing Much of animal energy expenditure is due to muscle activity, which is regulated primarily by behavior (e.g. Ellerby and Askew, 2007 ). Muscle activity is also regulated at the molecular level in ways that affect both mechanical...

..., we found a gene, HvAPX1 , coding for a plant-related ascorbate peroxidase. HvAPX1 is expressed exclusively during oogenesis and in contrast to all known ascorbate peroxidase genes in plants does not contain introns. No member of this gene family has previously been identified from a member...

...C. S. Bjornsson; E. Huebner SUMMARY The spatiotemporal dynamics of transmembrane hydrogen ion (H + )fluxes during oogenesis were investigated in the telotrophic ovarioles of the insect, Rhodnius prolixus . Although Rhodnius ovarioles possess exaggerated morphological and electrical polarity between...

..., of the ovarian follicles at some stage during oogenesis. We have shown that the mosquito Anopheles stephensi responds in this manner when ookinetes of the malaria parasite Plasmodium yoelii nigeriensis first begin to invade the midgut. Little is known about the initiation and regulation of follicle resorption...
