Sex differentiation studies relating to releaser aggregation pheromones of the desert locust, Schistocerca gregar
Behavioural responses of nymphs and adults in the gregarious phase of the desert locust, Schistocerca gregaria (Forskal) (Orthoptera: Acrididae) were investigated in a single-chamber bioassay system to a choice of two ...
Time-course haemolymph juvenile hormone titres in solitarious and gregarious adults of Schistocerca gregaria, and their relation to pheromone emission, CA volumetric changes and oocyte growth
The haemolymph JH III titres in solitarious and gregarious adult desert locusts, Schistocerca gregaria, were examined in relation to corpus allatum (CA) volumes, aggregation–maturation pheromone production in males and ...
The Role of Different Components of the Pheromone Emission of Mature Males of the Desert Locust, Schistocerca Gregaria (Forskål) (Orthoptera: Acrididae) in Accelerating Maturation of Immature Adults
(Cambridge University Press, 2011-09-11)
Different blends of five chromatographically prominent components of the pheromone emission of gregarious-phase mature desert locust Schistocerca gregaria (Forskål) (Orthoptera: Acrididae) males were bioassayed for their ...
Evidence for Additional Pheromonal Components Mediating Oviposition Aggregation in Schistocerca gregaria
(Kluwer Academic Publishers-Plenum Publishers, 1999-04)
Studies on the maturation-accelerating pheromone of the desert locustSchistocerca gregaria (Orthoptera: Acrididae)
The accelerating effect of mature males of the desert locust,Schistocerca gregaria, on the maturation of immature male and female conspecifics was confirmed. The onset of sexual activity was found to correlate with yellowing ...
Novel cross-stage solitarising effect of gregarious-phase adult desert locust (Schistocerca gregaria (Forskål)) pheromone on hoppers
(Science Direct, 2010-06)
Previous studies had demonstrated stage differentiation in the cohesion (aggregation) pheromone systems of the desert locust, Schistocerca gregaria. In laboratory arena, the nymphal and adult stages responded aggregatively ...
Aggregation pheromone system of nymphal gregarious desert locust,Schistocerca gregaria (forskål)
(Kluwer Academic Publishers-Plenum Publishers, 1996-12-01)
Hexanal, octanal, nonanal, decanal, hexanoic acid, octanoic acid, nonanoic acid, and decanoic acid were identified in the volatile emissions from fifth instars ofSchistocerca gregaria by coupled gas chromatography-electr ...
Haemolymph pigment composition as a chemometric indicator of phase in the desert locust, Schistocerca gregaria
(Cambridge University Press, 2011-09-19)
The blue biliverdin pigment in the haemolymph of Schistocerca gregaria Forskål (Orthoptera: Acrididae) was shown to be associated with all the stages and ages of the solitary-reared (solitarious) insects, irrespective of ...
Phase-independent responses to phase-specific aggregation pheromone in adult desert locusts, Schistocerca gregaria (Orthoptera: Acrididae)
Volatiles from solitary-reared (solitarious) and crowd-reared (gregarious) adult male desert locusts, Schistocerca gregaria (Forskal) (Orthoptera: Acrididae), were quantitatively and qualitatively different. In particular, ...
Aggregation pheromone system of adult gregarious desert locust schistocerca gregaria (forskal)
(Kluwer Academic Publishers-Plenum Publishers, 1994-07-01)
Six electrophysiologically active aromatic compounds, viz., anisole, benzaldehyde, veratrole, guaiacol, phenylacetonitrile, and phenol, were identified in the volatiles of older-adult male desert locust. Young adults and ...
