Condensed tannins can not effect on population development of jassid in cotton crop. Is it happening because of the strong detoxifying mechanism of jassid?
Both physical and biochemical parameters influence jassid development in cotton. Its gossypol rather than tanins which influence much.
Trichomes density highly significant and negatively influence on jassid population. But phenol, gossypol and condensed tannin positively correlated.
Dear Sir, Prof. Shashikant S. Udikeri
I am hurry why phenol, gossypol and condensed tannin positively correlated with jassid population when these substances are playing role as plant defense mechamism. Why Jassid detoxify these compounds or any other reason.
Actually gossypol has negative impact,but,when others,especially sugars excel the impact it happens so.
