The Small Cabbage White ( Pieris rapae) is originally a Eurasian butterfly. Being accidentally introduced into North America, Australia, and New Zealand a century or more ago, it spread throughout the continents and rapidly established as one of the most abundant butterfly species. Although it is a serious pest of cabbage and other mustard family plants with its caterpillars reducing crops to s...
Transcript patterns elicited in response to attack reveal, at the molecular level, how plants respond to aggressors. These patterns are fashioned both by inflicted physical damage as well as by biological components displayed or released by the attacker. Different types of attacking organisms might therefore be expected to elicit different transcription programs in the host. Using a large-scale...
Plants have evolved a variety of mechanisms for dealing with insect herbivory among which chemical defense through secondary metabolites plays a prominent role. Physiological, behavioural and sensorical adaptations to these chemicals provide herbivores with selective advantages allowing them to diversify within the newly occupied ecological niche. In turn, this may influence the evolution of pl...
Cyanide is generated in larvae of the glucosinolate-specialist Pieris rapae (Lepidoptera:Pieridae) upon ingestion of plant material containing phenylalanine-derived glucosinolates as chemical defenses. As these glucosinolates were widespread within ancient Brassicales, the ability to detoxify cyanide may therefore have been essential for the host plant shift of Pierid species from Fabales to Br...
The efficacy of a bio compound, Protecto (Bacillus thuringiensis) and botanicals extract (mixture ginger, garlic, hot red pepper extracts aloe vera) either in combination with Trichogramma evanescens releases or alone was evaluated comparison to an insecticide, Uphold 36% SC (Methoxyfenozide/ Spinetoram) on Pieris rapae cauliflower Brassica oleracea. Field experiments were conducted at Atfih Di...
