Stink Bug Feeding Induces Fluorescence in Developing Cotton Bolls
BACKGROUND Stink bugs (Hemiptera: Pentatomidae) comprise a critically important insect pest complex affecting 12 major crops worldwide including cotton. In the US, stink bug damage to developing cotton bolls causes boll abscission, lint staining, reduced fiber quality, and reduced yields with estimated losses ranging from 10 to 60 million dollars annually. Unfortunately, scouting for stink bug ...
متن کاملWater deficit and ethylene evolution by young cotton bolls.
Ethylene evolution and abscission of young cotton (Gossypium hirsutum L.) bolls were shown, in earlier papers, to increase when plants were subjected to conditions that decreased photosynthesis and sugar content of bolls (dim light, long warm nights). Moisture stress also increased ethylene evolution by young bolls, but it did not decrease their concentrations of fructose, glucose, or sucrose. ...
متن کاملEffects of some organic solvents on ethylene evolution from young cotton bolls.
The presence of promoter(s) of ethylene biosynthesis in young cotton (Gossypium hirsutum L.) fruits (bolls) was demonstrated by injection of an aqueous extract from bolls into other bolls and measurement of a 3-fold increase in rate of ethylene evolution. Injection of methionine did not affect rate of ethylene production, indicating that the promoter extracted from bolls was not methionine. Inj...
متن کاملLED-Induced fluorescence and image analysis to detect stink bug damage in cotton bolls
BACKGROUND Stink bugs represent a major agricultural pest complex attacking more than 200 wild and cultivated plants, including cotton in the southeastern US. Stink bug feeding on developing cotton bolls will cause boll abortion or lint staining and thus reduced yield and lint value. Current methods for stink bug detection involve manual harvesting and cracking open of a sizable number of immat...
متن کاملVerde plant bug (Hemiptera: Miridae) feeding injury to cotton bolls characterized by boll age, size, and damage ratings.
The verde plant bug, Creontiades signatus (Distant), has been present in south Texas for several years but has more recently been documented as an economic threat to cultivated cotton, (Gossypium hirsutum L. Our studies over 2 yr (2009 and 2010) and two locations (Weslaco and Corpus Christi, TX) investigated feeding-injury of the verde plant bug to a range of cotton boll age classes defined by ...
