Abstract

Population dynamics of fruit flies Bactrocera cucurbitae (Coquillett) was studied on cucumber (Cucumis sativus L.) variety Cucumber Gautam-910, during summer season 2020-21 and 2021-22 at College of Horticulture, Mandsaur (M.P.). The studies revealed that, for seasonal incidence, the fruit fly was found damaging and remained active on cucumber attaining peak population in the 18th SMW (52.62%) in 2020-21 and 17th SMW (30.29%) during 2021-22. The correlation studies showed that the fruit fly population was significant and positively correlated with Maximum temperature (r= 0.7246, r= 0.7454) and minimum temperature (r= 0.5367, r= 0.7871), significant and negatively correlated with relative humidity (r= -0.5949, r= -0.5598) whereas, rainfall (r= -0.0870, r = 0.1846) and rainy days (r= -0.1158, r =1.000) exhibited non-significant positive correlation in both year respectively.

Keywords

Cucumber, correlation, fruit fly, meteorological parameters, incidence

Conclusion

The present study conclude various Abiotic factors like temperature, relative humidity, rain fall and rainy days were affect the sucking insect pest population and their multiplication, whereas temperature and relative humidity showed significant and rain fall, rainy day showed non significant correlation.
