Attraction of <i>Idioscopus clypealis</i> (Leith) (Cicadellidae: Homoptera) to Sticky Colored Traps in Mango Orchard

Abstract

The present study was conducted at the Faiz Chaman mango orchard, Multan to find out the attraction of mango hopper Idioscopus clypealis to sticky traps of different colors. The experiment was laid out in randomized complete block de sign ed with three replications. The sticky traps were hung vertically with the branch/twig under the canopy of mango trees. Data w ere recorded under binocular stereoscope. Results indicated significant differences in the number of I . cly pealis (adults) captured in the different colored sticky traps. Yellow color was found most attractive with a capture of highest number of adults of I . clypealis (11.53 adults/trap). While pink and purple colors were found less attractive. The peak population of mango hoppers was recorded at the 31.96 &deg C during 25-April to 9-May. Yellow sticky traps were found most effective in trapping a considerably higher number of hoppers throughout the study period. Correlation analysis revealed a strong positive correlation between temperature and the mean number of I . clypealis adults. Popula tion peaks of I . clypealis were recorded at temperatures >30 &deg C, while at lower temperatures relatively low numbers of adults were recorded.
