Nutritional Performance of the Tomato Fruit Borer, Helicoverpa armigera, on Different Tomato Cultivars
The development and cultivation of tomato cultivars that are resistant to the tomato fruit borer, Helicoverpa armigera (Hübner) (Lepidoptera: Noctuidae), are very limited in Iran and other parts of the world because of the lack of information about resistant tomato cultivars to minimize the use of insecticides. Therefore, the present study was carried out to identify alternative methods to chem...
متن کاملEfficacy of Some Synthetic and Biopesticides Against Pod Borer, Helicoverpa armigera (Hubner) in Chickpea
Efficacy of some synthetic and biopesticides against pod borer, Helicoverpa armigera (Hubner) damage in chickpea was studied at the Regional Agricultural Research Station, Ishurdi, Pabna, Bangladesh during rabi cropping season of 2004-05. Synthetic and biopesticides reduced pod borer damage significantly. Significantly lowest pod damage was observed in cypermethrin (5.75%) and HNPV (5.86%) spra...
متن کاملRole of salicylic acid in tomato defense against cotton bollworm, Helicoverpa armigera Hubner.
We investigated the role of the salicylic acid (SA) signaling pathway in defense responses of tomato plants to the herbivore, cotton bollworm. After exposure to the cotton bollworm, tomato leaves rapidly accumulated a high level of SA. The transcription of PR1 and BGL2 genes, the marker genes of SA pathway, was up-regulated. An enhanced endogenous SA level was accompanied by an increase in the ...
متن کاملResponse of Cotton Bollworm Helicoverpa armigera (Hubner) (Lepidoptera:noctuidae) to Different Insecticides in Maharashtra, India
This study deals with Insecticide Resistance Management of cotton bollworm Helicoverpa armigera to five commonly used insecticides on cotton were carried out during 2008. In August, LD value for 50 chlorpyriphos varies from 0.046μg/larva in Parbhani district to 0.172 mg/larva during October in Aurangabad district. Resistance to chlorpyriphos was highest in Aurangabad district (3.65-8.25 fold) f...
متن کاملImpact of differential feeding on the growth and development of Helicoverpa armigera (Hubner).
The growth and development of Helicoverpa armigera was observed in the laboratory by feeding them on different foods viz; leaf, flower and fruit of lady finger, cotton, pigeon pea and chick pea. Based on the food ingested, food digested and food excreted as well as on weight and size of the larvae and the duration of larval period, the fruit of chick pea was found to be the most suitable food f...
