the developmental period, prey consumption of different nymph instars, survival, reproduction and longevity of orius albidipennis were studied on three different diets including the two-spotted spider mite, tetranychus urticae plus corn pollen; two-spotted spider mite; and eggs of sitotroga cerealella plus corn pollen under laboratory conditions. leaves of pelargonium hortom served as ovipositi...

Introduction A changing environment can select on life-history traits and trade-offs in a myriad of ways. For example, global warming may shift phenology thus the availability host-plants. This alter selection survival fertility schedules herbivorous insects. If life-histories changes, this turn for altered nutrient intake, because blend nutrients organisms consume helps determine expression tr...

An intravenous injection of arginine vasotocin (AVT) at 16 h before the expected oviposition of the initial egg of an egg-laying sequence caused bearing down for oviposition. Oviposition was increased up to 100% by increasing the dose of AVT up to 1 microg, but it decreased when the dose was 10 and 20 microg. Bearing down was observed even when the oviposition was not induced by the injection o...

Oviposition is a major event in the life history of mosquitoes, shaping both individual fitness and vectorial capacity. Several exogenous factors have been shown as important for the dynamic forcing of oviposition at finely (hourly) and coarsely (monthly or season to season) grained temporal scales. However, field studies addressing the interplay of weather factors on oviposition dynamics at th...

IntraspeciÞc geographic variation in morphology and behavior can be indicative of populations that are adapted to local environmental conditions. Heterogeneity in the abiotic environment, such as soil conditions, can be an important driver of local adaptation. In southFlorida,mean body sizes in populations of the lubber grasshopper Romalea microptera (Beauvois) (Orthoptera: Acrididae), increase...

Selection of oviposition sites by gravid females is a critical behavioral step in the reproductive cycle of Anopheles coluzzii, which is one of the principal Afrotropical malaria vector mosquitoes. Several studies suggest this decision is mediated by semiochemicals associated with potential oviposition sites. To better understand the chemosensory basis of this behavior and identify compounds th...

Infections can have detrimental effects on the fitness of an animal. Reproducing females may therefore be sensitive to cues of infection and be able to adaptively change their oviposition strategy in the face of infection. As one possibility, females could make a terminal investment and shift reproductive effort from future to current reproduction as life expectancy decreases. We hypothesized t...

1. Transection of the ventral nerve cord of female grasshoppers activates the rhythmical motor programme for oviposition digging. 2. Electrical stimulation of the cut nerve cord had the following effects on elicited oviposition motor activity: (i) shortand long-lasting inhibition of activity, (ii) phase resetting and (iii) modulation of burst frequency. 3. Cold saline applied to the nerve cord ...
