Fecundity is defined in two ways; in human demography, it is the potential for reproduction of a recorded population as opposed to a sole organism, while in population biology, it is considered similar to fertility, the natural capability to produce offspring, measured by the number of gametes (eggs), seed set, or asexual propagules. Adult fecundity Newly-emerged adults (â™€:â™‚=) were paired, transferred to mL plastic cups with a sterile gauze stopper and fed with nine different food items: distilled water (water), 5% (v/v) acacia honey (Beijing Baihua Bee Co., Ltd., Beijing, China) dissolved in distilled water, 5â€° (m/v) corn pollen dissolved in.
Adult feeding was proved by the presence of the dye within the digestive system of adults of P. operculella. Although the oviposition rate and fertility were not affected by adult feeding, female fecundity was higher in honey-fed females as compared to the water-fed females. Daily fecundity (number of nymphs produced per adult per day) varied with time for both aphid species and in each experiment (fig. 2). From the Cambridge English Corpus These .
Gaining weight in adulthood, being overweight or obese in adulthood, and being underweight at age 18 years were associated with a modest reduction in fecundity.
