MONITORING OF CODLING MOTH CYDIA POMONELLA (L.) THROUGH PHEROMONE TRAPS IN APPLE ORCHARD

Abstract

A trial was conducted using RCBD design at Barkhan (Baghao) province Balochistan. Pheromone traps (04) were placed among the apple trees for the collection of the adult codling moth. These traps were hung on four randomly selected Apple tree at height of 2.5 meters with adjacent of five trees. The result indicated that the first flight of C. pomonella population (7.20±0.40 moths per trap) was observed in 17th standard metrological week. Afterwards, the C. pomonella population increases gradually 8.50±1.10 moths per trap in the 21ststandard metrological week. The maximum C. pomonella population (12.68±1.12 moths per trap) was recorded during the 28th standard metrological week. Minimum C. pomonellapopulation (5.10±0.51 and 5.53±2.10 moths per trap) was recorded during 18th and 20thstandard metrological week, respectively. Correlation studies indicates that there was positive and highly significant (p<0.01) association (r=0.849) for maximum and minimum temperatures (r=0.7130). While, there was significant but negative association (r= -0.359) for relative humidity with target pest population. In a similar way, there was negative and non-significant relationship (r= - 0.004) for total rainfall with C. pomonella population. After going through the results indetail, it was concluded that pheromone trap were found effective for control codling moth of apple.
