Abstract
The effect of an integrated pest management (IPM) package, host plantresistance, Chrysoperla carnea predation and neem oil wereevaluated against the spider mite Tetranychus ludeni oneggplant(Solanum melongena L.) fields in 1996 and 1997, byestimating the mite population density and yield levels. Compared with the IPMpackage (Panruti local, C. carnea plus neem oil), thestandard (susceptible) eggplant variety (MDU1) grown by farmers andtreated with an acaricide (dicofol) had significantly higher mite densities.Thepredator C. carnea was recorded in significantly lowernumbers in plots with the standard variety compared to a resistant variety(panruti local) with the full IPM package. Eggplant yield level and crop valuewere highest in the IPM-treated plots followed by Panruti local plusC. carnea. The standard variety treated with an acaricidehad the lowest yield and value. These results indicated the usefulness of hostplant resistance complemented by biorational control agents, such asC. carnea and neem oil, that these are suitable componentsin an IPM programme for managing the spider mite in endemic areas.
