The desert locust, Schistocerca gregaria (Forskål) (Orthoptera: Acrididae), a major Old World pest, is associated with agricultural losses and undesirable societal effects. There are three broad approaches to its control: reaction, proaction, outbreak prevention. Reaction protects crops from swarms but it costly disruptive. Proaction involves early intervention during outbreaks avert further development plague status; in current use because effective, relatively inexpensive, the best...
Abstract All terrestrial ectotherms are constrained to some degree by their thermal environment and the extent which they can behaviorally buffer variable conditions. New biophysical modeling methods (NicheMapR) allow calculation of body temperature thermoregulating animals anywhere in world from first principles, but require detailed observational data for parameterization testing. Here we describe thermoregulatory biology marching bands desert locust, Schistocerca gregaria , Sahara Desert...
Abstract Oviparous animals often prioritize the allocation of reproductive resources to egg size over clutch size, but impact this maternal investment on embryonic yolks and its ecological functions is poorly understood. We investigated how desert locust embryos allocate yolk for survival energy after hatching, rather than somatic growth depending in response desiccation stress. Crowd-reared females (gregarious phase) produced significantly larger progeny with higher tolerance starvation...
The effects of a neurohormone, [His(7)]-corazonin, on phase-related morphological traits (F/C and E/F ratios; F = length the hind femur, C maximum width head; E fore wing) were re-examined in desert locust, Schistocerca gregaria Forskål. F/C ratio was significantly different between adults with five six nymphal instars, respectively, indicating that they need to be analysed separately. Injections synthesized peptide (1 nmol) into individually-reared (solitary) nymphs at second third instars...
Abstract Locusts modify developmental and reproductive traits over successive generations depending on the population density. A trade-off between rate body size progeny number is often observed in organisms. In this study, we present evidence that rule evaded by desert locusts, Schistocerca gregaria Forskål, which undergo outbreaks. Under isolated conditions, large hatchlings, typical of gregarious forms, grow faster but emerge as larger adults than do small hatchlings solitarious except...
The Desert locust Schistocerca gregaria is a major world pest that causes substantial agricultural and economic damage. Effective control relies on effective monitoring, which requires knowledge of microhabitat selection. Yet little known about selection solitarious adult locusts in the field. We conducted field surveys to investigate fine-scale diel temporal spatial distributions adults Sahara Mauritania, breeding recession area. found moved among different, specific microhabitats...
Significance In animal societies, social life often generates male mating harassment. How do communal animals manage such conflicts without escalating antagonistic relationships? the Sahara Desert, we studied system of gregarious-behaving desert locusts, world’s most destructive locust. Despite being widespread and abundant during plagues, its populations are otherwise difficult to access, reproductive behaviors in field understudied. We show that female locusts behaviorally overcome costs...
Abstract Group living has various benefits, but it also carries costs, such as risk of cannibalism. Molting is a vulnerable period being cannibalized in juvenile arthropods, how gregarious arthropods avoid this threat poorly understood. Here, we examined actively migrating nymphs desert locust, Schistocerca gregaria, cannibalism during molting, the Sahara Desert Mauritania. In field, cyclically march and feed on grass day. Our field observations found that marching behavior helped separating...
Abstract The influences of hatchling character and rearing density on body colour at the last‐nymphal stadium are investigated for desert locust, Schistocerca gregaria . Hatchlings divided into five groups based darkness reared either under isolated or crowded conditions. Two types variation separately analysed (i.e. background black patterns). Under conditions, is greenish brownish. Most individuals highest percentage brownish insects obtained from hatchlings with darkest colour. yellow...
