Abstract:

The population dynamics studies were carried out in the orchard of CCS HAU, Hisar from April to November during 2016 on kinnow (Citrus nobilis × Citrus deliciosa). The citrus butterfly is one of the economically important pests whose larval forms cause serious damage by devouring large quantity of foliage of Rutaceae family with special preference towards both wild and cultivated species of citrus during the later stages of their development. Population density was determined on randomly selected five rows (10 plants each row) of kinnow at weekly interval and recorded on the basis of number of larvae per plant. The average larval population and leaf infestation percentage of citrus butterfly, Papilio demoleus L. was varied from 0 to 16.01 and 0-56.73/ five replicate in 16th to 47th standard meteorological weeks (SMW). The average temperature varied from 43.10C- 10.00C (maximum-minimum) whereas R.H 94-19% (morning-evening) and a rainfall of 2.8-93.5 mm during the experimental period. The peak activity of larval population was in 39th standard metrological week (16.01/ five replicate) when average temperature was minimum (35.0-23.80C) and relative humidity maximum (90-71%). The lowest average population of caterpillar i.e. 0 larva/5 replicates of kinnow was recorded in 18th, 20th, 21st and 24th to 28th SMW. The larval population of citrus butterfly were shows the significant positive correlation (r =0.556-0.455) with relative humidity (M-E) and significant negative correlation with maximum and minimum temperature (r = -0.544 and 0.254) whereas non-significant correlation with rainfall and sunshine hrs and same trend were follow in case of leaf infestation. The kinnow plants were more infested by P. demoleus during rainy season followed by summer. The study may be useful in the formulation of control strategy of this pest.
