Herbivore specialists adapt to feed on a specific group of host plants by evolving various mechanisms to respond to plant defenses. Insects also possess complex gut microbiotas but their potential role in adaptation is poorly understood. Our previous study of the genome of diamondback moth, Plutella xylostella, revealed an intrinsic capacity to detoxify plant defense compounds, which is an impo...
Understanding dispersal and gene flow is an important focus of evolutionary biology, conservation biology and pest management. The diamondback moth, Plutella xylostella, is a worldwide pest of Brassica vegetable and oilseed cropping systems. This insect has high dispersal ability, which has important consequences for population dynamics and the potential spread of insecticide resistance genes. ...
Although the mode of action of Cry1A toxins produced by Bacillus thuringiensis is fairly well understood, knowledge of the molecular mechanisms by which lepidopteran species have evolved resistance to them is still in its infancy. The most common type of resistance has been called "Mode 1" and is characterized by recessive inheritance, >500-fold resistance to and reduced binding by at least one...
A field survey in the farmers’ fields at Gurugram Haryana, few blocks focused on incidence of pests cabbage and cauliflower during rabi, 2017-18 2018-19. These revealed occurrence Plutella xylostella Spodoptera litura. Maximum number larvae P. S. litura was recorded Pataudi block as compared to those Farukhnagar, Sohana Gurugram. Seven neem-based biopesticides were evaluated along with check ca...
Cyantraniliprole belongs to new chemical class of diamides and used Plutella xylostella one the highly devastating lepidopteran insect pests cole crops has been found develop resistance cyantraniliprole worldwide including India . However their mechanism is not examined in Indian scenario. Hence a survey was conducted analyse current status field population P. cyantraniliprole. The maximum leth...
Potential trap crops for the diamondback moth, Plutella xylostella (L.) (Lepidoptera: Plutellidae), were evaluated through a series of ovipositional preference and larval survival experiments in outdoor screenhouses in 2002 and 2003. Hosts examined as trap crops were glossy and waxy collards, Brassica oleracea L. variety acephala; Indian mustard, Brassica juncea (L.) Czern; and yellow rocket, B...
