| dc.description.abstract | Investigations on the diversity and monitoring of fruit flies by using methyl eugenol traps were earned out.at the University of Agricultural Sciences, Dharwad, Kumbapur, Morigere, Ranebennur and Hulkoti from January 2001 to May 2002 in different crop ecosystems. Four species of fruit flies namely Bactrocera zonata, B. correcta, B. dorsalis and B. cucurbitae were trapped in mango, guava and cucurbits. In ber, besides these species, B. nigrotibialis was trapped and C. vesuviana was recorded from the infested fruits. B. dorsalis was the most dominant species. In mango orchards, B. dorsalis had three peaks at Dharwad (21st, 23rd and 46th standard weeks), two peaks at Kumbapur (22nd and 47thstandard weeks) and one peak at Hulkoti (20th standard week). In guava, B. dorsalis had one peak (45* standard week) at Dharwad and three peaks (43rd, 45th and 47th standard weeks) at Kumbapur. In ber, B. dorsalis had one peak at Morigere (50th standard week). In cucurbits, B. dorsalis and B. cucurbitae reached a peak during 44th standard week at Ranebennur. Maximum larvae of 0.75 per fruit and fruit infestation of 30.0 per cent was recorded in mango. Similarly in guava and ber 0.70 and 0.52 larvae/fruit and fruit infestation of 46 and 34 per cent were observed, respectively. There was significant positive correlation between fruit infestation and trap catch. In mango, B. zonata and B. correcta had significant positive correlation with minimum temperature at Dharwad, while at Kumbapur, both the species had positive correlation with maximum temperature and minimum temperature. 6. dorsalis and 5. cucurbitae had no relationship with all the weather parameters. In guava B. zonata and B. correcta had highly significant positive correlation with maximum temperature and highly significant negative correlation with morning relative humidity at Dharwad. At Kumbapur both the species had positive correlation with maximum temperature and afternoon relative humidity. | en_US |
