The present study aims to understand the influence of two thermal extremes (15°C and 35°C) as thermal stressors on the selected line of developmental variants (slow and fast developers) in Propylea dissecta and to compare it with the response at the optimal temperature (27°C).

Functional and numerical responses of Propylea dissecta (Col., Coccinellidae)
Journal of Applied Entomology, 2004Abstract:The functional response of a ladybeetle, Propylea dissecta, to increasing density of aphid, Aphis gossypii, was of the curvilinear shape depicting Holling's type II response with fourth instar larva being the most voracious stage when compared with adult male and female.

Ladybird beetles are predatory insects, which consumes everal insect pests and have immense biocontrol potential, particularly against aphids. In prey scarcity, they resort to intraguild predation (IGP) by consuming immature stages of other heterospecific ladybirds.

Abstract Intraspecific variation is the variation in morphology, physiology, behaviour, and social organisation of any species as it adapts to changing environmental circumstances by varying its feeding habits. In the present study, we investigated the disparities between the preselected (F1) and postselected (F15) populations of Propylea dissecta ...

Abstract:Development and survival of the immature stages of an aphidophagous ladybeetle, Propylea dissecta (Mulsant) was investigated at five constant temperatures, viz. 20, 25, 27, 30 and 35°C, using Aphis gossypii Glover as prey. Developmental period of all the life stages were significantly affected with change in constant temperature and ...

Abstract: In the present study the influence of maternal and paternal ages on reproductive performance of an aphidophagous ladybird, Propylea dissecta (Mulsant) were investigated. Maternal age strongly influenced fecundity and pre‐oviposition period while paternal age strongly influenced the egg viability.

Adult pale morphs of an aphidophagous lady beetle, Propylea dissecta (Mulsant) (Coleoptera: Coccinellidae), were reared on a non-insect diet for periods ranging from 0 to 30 days after eclosion. The prey-deprived females, when provided with the cowpea aphid, Aphis craccivora Koch (Homoptera: Aphididae), laid fertile eggs, indicating that they had ...

Abstract Remating rate is a fundamental parameter that acts on disease transmission, sexual dimorphism, and the rate of evolution of species. Recent studies have indicated that sperm production can be costly. It is thus likely that males may tailor their sperm expenditure according to female mating status and the remating interval between successive ...

AbstractThe effects of environmental parameters on insect development have been studied extensively. But the reasons for 2 differential developmental rates within same cohort under varying environmental factors have not been explored. For the purpose, in this study the existence and stability of slow and fast development under 5 photoperiods (i.e., 8L:
