behaviour of coconut mites preceding take-off to passive aerial dispersal.for more than three decades the coconut mite aceria guerreronis keifer is one of the most important pests of coconut palms and has recently spread to many coconut production areas worldwide. colonization of coconut palms is thought to arise from mites dispersing aerially after take-off from other plants within the same plantation or other plantations. the underlying dispersal behaviour of the mite at take-off, in the airborne state and after landing is largely unknown and this is essential to un ...201425033769
host finding behaviour of the coconut mite aceria guerreronis.for the coconut mite, aceria guerreronis keifer, its host plant, the coconut palm, is not merely a source of food, but more generally a habitat to live in for several generations. for these minute organisms, finding a new plant is difficult and risky, especially because their main mode of dispersal is passive drifting with the wind and because they are highly specialized on their host plant. consequently, the probability of landing on a suitable host is very low, let alone to land in their speci ...201425033768
efficacy of aggregation pheromone in trapping red palm weevil (rhynchophorus ferrugineus olivier) and rhinoceros beetle (oryctes rhinoceros linn.) from infested coconut palms.red palm weevil and rhinoceros beetle are the major pests inflicting severe damage to coconut palms. due to ineffectiveness of the current management practices to control the two important pests on coconut, a study was conducted to know the attractiveness of red palm weevil and rhinoceros beetle to aggregation pheromone. olfactometer studies indicated that the aggregation pheromone of red palm weevil and rhinoceros beetle attracted significantly more number of weevils (13.4 females and 7.6 male ...201424813002
