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.
