Effect of wind on the reduction of red cucurbit mite, Tetranychus neocaledonicus Andre (Acarina: Tetranychidae) population
1982 - Volume: 23 Issue: 2 pages: 145-147
dispersal of Tetranychids
Effect of various wind velocities, viz. 10.8, 19.8, 25.2, 30.6, 34.2 and 37.8 km./hour on the dislodgement of the cucurbit mite, Tetranychus neocaledonicus Andre was studied on two susceptible hosts - bottle gourd (variety: Kalyanpur long green, summer) and pumpkin (variety: local). With the increase in wind velocity, dislodgement of mites also increased significantly and both hosts followed almost the same trend. Dislodgement was recorded to be more on bottle gourd as compared to pumpkin. This was perhaps due to morphological characters of the leaf.
