Wheat-pea intercropping for aphid control: from laboratory tritrophic approach to field application - IJAAR

Abstract

Intercropping is an interesting practice to promote the sustainable control of insect pests such as aphids. In particular, volatile organic compounds emitted by aphid-infested intercropped plants may deter other aphid species from their host plants, while attracting natural enemies. In this study, olfactometer and net-cage behavioural assays were first conducted to determine the effect of wheat-pea mixtures combined with aphid infestations on odour preferences of the wheat aphid Sitobion avenae and two associated predator species, the ladybird Harmonia axyridis and the hoverfly Episyrphus balteatus.

Abstract

In this investigation MS media supplemented with different concentrations of GA3 viz. 0.00, 0.12, 0.25, 0.50, 0.75mg/L were used for in vitro micro propagation of potato varieties Cardinal and Desiree. The parameters included were percent sprout, plantlet height, number of nodes per plantlet, number of days to root initiation, and number of days to transferable height of the plantlets.

Abstract

The present study was carried out for the development of the water stress wheat cultivars with higher grain yield by studying the genetic basis of crucial morphological traits. Nine wheat genotypes were grouped into six lines and three testers and these parents were crossed line x tester fashion.
