Online published on 23 December, 2016. Abstract Survey on primary fruit piercing moths at sweet orange orchard of Department of Horticulture, MPKV, Rahuri was conducted during June 2012-May 2014 at weekly interval revealed that the activity of fruit piercing moth population was observed from last week of August to last week of November. Highest population of 89.5 moths/week was observed during second week of September. The species wise catches of E. materna, E. fullonia, E. homaena and T. coronata were recorded as 59.5, 22.0, 4.5 and 3.5 moths/week, respectively. E. materna was found to be most predominant species in Maharashtra. Correlation studies with weather parameters and fruit piercing moth incidence revealed the positive correlation between the population of four species of FSM with rainfall, number of rainy days, minimum temperature, maximum temperature, morning relative humidity and evening relative humidity. Whereas, the population of E. materna, E. fullonia, E. homaena and T. coronata showed positive correlation with rainy days, morning and evening relative humidity, maximum and minimun temperture during 2013. However, the wind velocity had negative correlation with the incidence of fruit piercing moths. Top Keywords Seasonal abundance, fruit piercing moths, sweet orange. Top |
