Abstract

The present investigation on “Seasonal Incidence of Sucking Insect-Pests of Soybean [Glycine max (L.) Merrill]” was conducted during kharif, 2019 at Agricultural Research Station, Ummedganj, Agriculture University, Kota. The results revealed that among the sap feeding insects whitefly and jassid were reported on the crop almost all cropping period. Maximum infestation of whitefly (7.8/3 trifoliate leaf) observed in first week of September, whereas maximum number of jassid (2.8/3 trifoliate leaf) was recorded in third week of September. The correlation study reveals that the whitefly and jassid population showed significantly negative correlated with rainfall. Among all the pests. sucking pests have recently got more attention due to its widely destructive nature by acting as a vector of some virus diseases in soybean, such as yellow mosaic virus dissemination by Bemisia tabaci.

Seasonal, incidence, jassid, whitefly, correlation, peak, infestation

Conclusion

Study of population dynamics of insect pests is one of the most important objective of pest management. Population dynamics provides the data of seasonal fluctuation and peek activity of insect pests. Correlation study of insect pests with pest’s population also provides information about weather influence on insect pest population. The information collected in this study is useful in insect pest management.
