Description |
Investigations were carried out during the year 2005-06 at Dharwad and Mummigatti to evaluate the different quantity of methyl eugenol, frequency of charging, different colours and shapes of traps as well as protein food baits and the effect of weather on trap catches of fruit flies. Traps charged with 0.1 and 0.2 ml methyl eugenol in guava and mango respectively recorded higher trap catches. These traps could trap the fruit flies effectively upto 4 weeks and three weeks in guava and mango respectively against Bactrocera correcta. Whereas charging at two and four weeks intervals was effective against B. dorsalis and B. zonata respectively. Yellow coloured traps were found to be effective in guava (71.91 fruit flies/trap/week) and black colour in mango orchards (8.68 fruit flies/trap/week). Cylinder and bottle traps were efficient in guava (33.05 and 32.75 fruit flies/trap/week) ecosystem while bottle traps were efficient against mango fruit flies (7.23 fruit flies). Among various protein food baits, fruit fly diet, mango pulp with ammonium acetate combination attracted significantly more number of female fruit flies (10.63 and 8.88 fruit flies/trap/week). Monitoring studies revealed the occurrence of all the three species (B. correcta, B. dorsalis, B. zonata) throughout the year. In guava, B. correcta had four peak catches in 2005- 2006 while B. dorsalis had three during 2005 and one major peak catch during 2006 (April). In mango, B. correcta had two peaks in 2005 (July and November) and one in 2006 (May) while B. dorsalis had totally four peaks throughout the season (July and November of 2005 and March and May of 2006). However, B. zonata had only one major peak in 2005 (September) and two peaks in 2006 (April and May). In guava and mango high significant positive correlation was observed between trap catches and minimum temperature. |
