In Akola, overall good number of moth catches were observed in PCI –Delta Trap with replacement sticky liner [having pectin lure and pectin lure (season long)] and Phero – Sensor TM– SP – Sleeve Trap and Phero – Sensor TM– BP – Sleeve Trap than the regular funnel type trap. In Banswara, the maximum moth catches/trap/week was recorded in Phero – Sensor TM– BP – sleeve trap with PBW lure and it was statistically at par with Phero – Sensor TM– SP – sleeve trap with PBW lure. In Nanded, significantly maximum population (6.36 moths per trap) was observed in Delta trap with replacement sticky liner- pectino lure SL.

In Surat, the pooled data on larval population of P. gossypiella was observed significantly lowest in T. bactrae release treatment (1.91%) and it was at par with insecticidal spray (2.11%). Damage to green boll, open bolls and locule damage by pink bollworm was found significant lower in T. bactrae release followed by insecticidal spray. The pollinators/honey bee activity (Apis dorsata, A. cerena and Xylocopa sp.) were significant higher in T. bactrae release treatment at 65 and 95 days after flowering. The highest seed cotton yield was found in T. bactrae release plot (2223.90 kg/ha) and it was at par with insecticides sprayed plot (1978.84 kg/ha).

In Junagadh, among the all treatments were recorded significantly lower per cent green

(3.88 %) and T. bactrae(4.51%) than control. Significantly highest seed cotton yield (2401 kg/ha) was also obtained in insecticidal treatment and T. bactrae (2315 kg/ha).

In Guntur, the mean larval incidence was 1.59/ 10 green bolls in insecticidal treated plots which was found on par with 1.96/ 10 green bolls in T. bactrae released plots. The mean locule damage was 19.03 % in insecticidal treated plots, while it was 21.17 % in T. bactrae released plots without significant differences. However, both larval incidence and per cent locule damage were significantly high in untreated control when compared to insecticide treatments and T.bactrae released plots. This can be attributed to initial suppression of egg and first instar larvae of pink bollworm by T. bactrae or foliar sprays of insecticides. The good open bolls were high in insecticidal treated plots (32.31) and in T. bactrae released plots (29.31), when compared to to untreated control (24.74). The seed cotton yield was 16.07 q/ha in insecticidal treated plots and it was found statistically superior over T. bactrae released plots (14.13 q/ha). The seed cotton yield was 11.77q/ha in untreated control which was significantly lesser than both T.bactrae released plots and insecticidal treated plots.
