Differentiating tobacco budworm and corn earworm using near-infrared spectroscopy.
Near-infrared spectroscopy (NIRS) was used to develop a simple and quick technique to differentiate two economically important species, the tobacco budworm, Heliothis cirescens (F.), and corn earworm, Helicoverpa zea (Boddie), which are major pests of cotton, Gossypium hirsutum L., in the southern United States. In practice, it is difficult to distinguish the two species during their immature s...
متن کاملBacillus thuringiensis Cry1Ac resistance frequency in tobacco budworm (Lepidoptera: Noctuidae).
The tobacco budworm, Heliothis virescens (F.) (Lepidoptera: Noctuidae), is one of the most important pests of cotton, Gossypium hirsutum L, that has become resistant to a wide range of synthetic insecticides. CrylAc-expressing cotton has proven its effectiveness against this insect since its introduction in North America in 1996. However, the constant exposure of tobacco budworm to this protein...
متن کاملMeasuring Armenia's progress on the Tobacco Control Scale: an evaluation of tobacco control in an economy in transition, 2005–2009
OBJECTIVES This study aimed to measure the 5-year progress in the implementation of WHO Framework Convention on Tobacco Control (FCTC) in Armenia by applying the Tobacco Control Scale, a rapid assessment tool developed to assess the strength of tobacco control policies in Europe. SETTING Armenia, an economy in transition, has extreme smoking rates among men (62.5%) despite acceding to FCTC in...
متن کاملCharacterization of esterases associated with profenofos resistance in the tobacco budworm, Heliothis virescens (F.).
The utility of microplate and electrophoretic assays for detection of biochemical and physiological mechanisms underlying resistance to profenofos in the tobacco budworm, Heliothis virescens (F.), was assessed. Esterase (EST) activities were significantly higher in profenofos-resistant than -susceptible larvae, and activities were highly correlated (r(2) = 0.87) with resistance to profenofos. B...
متن کاملPlasma phenoloxidase of the larval tobacco budworm, Heliothis virescens, is virucidal
Heliothis virescens larval plasma contains high levels of an antiviral activity against the budded form of the Helicoverpa zea single nucleopolyhedrovirus (HzSNPV) in vitro. Preliminary results indicated that phenoloxidase is primarily responsible for this virucidal effect. However it is known that other enzymes that generate antimicrobial reactive oxygen intermediates and reactive nitrogen int...
