Cotton is more chemically intensive than many other commodities, which negatively impacts rural livelihoods at higher rates. Improvement in environmental stewardship of cotton would substantially impact the long-term sustainability agriculture producing regions globally. Extension personnel provide producer education to improve these issues that ultimately economic growth and quality life areas...

We identify a cytochrome P450 gene (CYP6AE14) from cotton bollworm (Helicoverpa armigera), which permits this herbivore to tolerate otherwise inhibitory concentrations of the cotton metabolite, gossypol. CYP6AE14 is highly expressed in the midgut and its expression correlates with larval growth when gossypol is included in the diet. When larvae are fed plant material expressing double-stranded ...

Three genes encoding polygalacturonase (PG) have been identified in Lygus lineolaris (Palisot de Beauvois) (Miridae: Hemiptera). Earlier studies showed that the three PG gene transcripts are exclusively expressed in the feeding stages of L. lineolaris. In this report, it is shown that all three transcripts are specifically expressed in salivary glands indicating that PGs are salivary enzymes. T...

background: gossypium arboreum is resistant to cotton leaf curl burewala virus and its cognate cotton leaf curl multan betasatellite (clcubuv and clcumb). however, the g. arboreum wax deficient mutant (gawm3) is susceptible to clcuv. therefore, epicuticular wax was characterized both quantitatively and qualitatively for its role as physical barrier against whitefly mediated viral transmission a...

Background: Gossypium arboreum is resistant to Cotton leaf curl Burewala virus and its cognate Cotton leaf curl Multan betasatellite (CLCuBuV and CLCuMB). However, the G. arboreum wax deficient mutant (GaWM3) is susceptible to CLCuV. Therefore, epicuticular wax was characterized both quantitatively and qualitatively for its role as physical barrier against whitefly mediated viral transmission a...

This paper investigates the extent to which world market price changes are transmitted through changes in border prices into local producer prices for four agricultural product markets in Tanzania: sugar, cotton, wheat and rice. The changes in the marketing channels for each of these products resulting from market liberalization are described. The statistical analysis finds that, in general, Ta...

Insect pests represent a significant limitation for production of many crops. Traditional reliance on pesticides brings significant economic costs and environmental liabilities of off-target drift, chemical residues and resistance. IPM has long been proposed as an alternative. The adoption of IPM in the Australian cotton industry provides a valuable overview of the key components of IPM and the...

Feeding by insect herbivores activates plant signaling pathways, resulting in the enhanced production of secondary metabolites and other resistance-related traits by injured plants. These traits can reduce insect fitness, deter feeding, and attract beneficial insects. Organic and inorganic chemicals applied as a foliar spray, seed treatment, or soil drench can activate these plant responses. Az...
