“…Kote, and Nanjanagudu taluks. This trend aligns with previous findings by Thippaiah (2004) [10] and Devi et al (2015) [2] , indicating an increase in infestation over the years due to expanded crop cultivation, limited farmer awareness, and inadequate pest management strategies. The survey also assessed the susceptibility of four banana varieties to pseudostem weevil infestation.…”

Laboratory studies on the biology of the banana pseudostem weevil, Odoiporus longicollis, unveiled key insights into its life cycle. The incubation period ranged from 3.00 to 4.00 days. Larval development comprised five instars, with durations of 2. 75, 4.05, 5.85, 6.65, and 13.15 days for instars I to V, respectively, resulting in a total larval duration ranging from 25.00 to 36.00 days. The pre-pupal period lasted for 2.00 to 5.00 days, while the pupal period varied from 15.00 to 21.00 days. The entire developmental period from egg hatching to adult emergence spanned from 48.00 to 65.00 days. Adult longevity ranged between 50.00 and 62.00 days. Females laid a total of 17.00 to 21.00 eggs in their lifetime. Field observations indicated varying levels of infestation across different taluks, with H.D. Kote taluk exhibiting the highest infestation rates across all crop stages, followed by Mysuru, T. Narasipura, and Hunsuru. Conversely, Nanjanagudu taluk registered the lowest infestation levels. Notably, the ratoon crop of the Nendran variety showed the highest infestation rate at 35%, followed by Nanjanagudu rasabale and Elakki varieties. In contrast, the G-naine variety displayed resistance to pest incidence. Additionally, the study highlighted a preference of the pest for ratoon crops over fresh crop stages of bananas, resulting in comparatively lower incidence in fresh crops.

“…Similarly, Mohammad Azam et al (2010) [3] observed the peak infestation period from July to September in the Jammu and Kashmir region. Additionally, Priyadarshini et al (2014) [4] noted peak incidence during the second fortnight of August in Bihar, while Devi et al (2015) [1] reported peak infestation in September (4.30%) and lowest infestation in December (0.00%) in West Bengal. The correlation study between various weather parameters and the percentage of infestation revealed consistent findings.…”

A study investigating the impact of season and crop stage on the incidence of the banana pseudostem weevil in the Mysuru region of Karnataka revealed that the pest's presence persisted throughout the year. However, two distinct peak periods of infestation were observed: one during August-September and another during March-April. The infestation levels varied from 11.50% to 41.75% regardless of the crop stage. In ratoon crops, the percentage of infestation ranged from 12.00% to 54.50%, whereas in fresh crops, it varied from 11.00% to 32.00%. Notably, the percentage of infestation in ratoon crops was observed to be higher than that in fresh crops. This trend can be attributed to the fact that the banana pseudostem weevil tends to infest crops that are more than five months old. In several fresh crop fields, the infestation levels were negligible or non-existent. The correlation study between various weather parameters and the percentage of infestation revealed consistent findings. Specifically, maximum temperature exhibited a negative correlation with the infestation percentage across all crop stages, while other weather parameters such as minimum temperature, minimum and maximum relative humidity, and rainfall showed a positive correlation with the infestation rate.
