The impact of cold storage on mating behavior of emerging adults and progeny fitness, in a parasitoid wasp, Lysiphlebus fabarum, under constant and fluctuating temperatures
Cold storage is a valuable method for reducing the cost of producing large amounts of biological agents. Fluctuating thermal regimes (prolonged exposures at low temperatures combined with periodic short higher temperature) are reported to improve cold survival and fecundity in some parasitoid species. In this study, the pupal stage of the parasitoid wasp Lysiphlebus fabarum (Marshall) (Braconid...
متن کاملInfluence of maternal age on the fitness of progeny in the rice weevil, Sitophilus oryzae (Coleoptera: Curculionidae).
We studied the effects of maternal age on fitness of progeny in the rice weevil, Sitophilus oryzae L. (Coleoptera: Curculionidae). Five-, 20-, and 50-d-old female rice weevils were used to study the effects of maternal age on the lifetime fecundity and longevity of their daughters. In addition, we determined the effects of maternal age on the weight and survivorship of daughters' progeny. Daugh...
متن کاملAnt Mimicry by an Aphid Parasitoid, Lysiphlebus fabarum
In Iran, Lysiphlebus fabarum (Marshall) (Hymenoptera: Braconidae: Aphidiinae) is a uniparental parasitoid of the black bean aphid, Aphis fabae Scopoli (Hemiptera: Aphididae), that possesses various highly evolved adaptations for foraging within ant-tended aphid colonies. Direct observations and video recordings were used to analyze the behavior of individual females foraging for A. fabae on bea...

15 صفحه اولDoes Maternal Age Affect Children’s Test Scores?
We estimate the relationship between maternal age and child outcomes, using indices aimed at measuring overall outcomes, learning outcomes, and social outcomes. In all cases, we find evidence that children of older mothers have higher outcomes. Not only do children born to mothers in their twenties do better than children born to teen mothers, but children born to mothers in their thirties do b...
