HOST RELATIONSHIP AND DAMAGE POTENTIAL OF THRIPS INFESTING CASHEW |
| Author: | T.N. ANANTHAKRISHNAN |
| Abstract:
Both phyllophilous and anthophilous thrips species infesting Anacardium occidentale are highly polyphagous enabling consistency of thrips population. Rhipiphorothrips cruentatus (Hood), Selenothrips rubrocinctus (Giard) and Retithrips syriacus (Mayet) infesting leaves tend to show patterns of infestation in relation to water stress as well as the distribution of nutrients. Sizeable populations of inflorescence infesting Scirtothrips dorsalis (Hood), Thrips hawaiiensis (Morgan) and Haplothrips ganglbaueri (Schmutz) cause premature shedding of flowers. The trends of infestation of different species along with some aspects of host plant preferences are discussed. | |
