“…Apart from the above, monitoring is considered as the keystone in any Integrated Pest Management (IPM)-based strategy against P. gossypiella [14,15]. This is usually carried out through samplings in the fruiting bodies of the plant, and, especially, the use of traps baited with the male attractant of the species, which is known commercially as gossyplure, i.e., Z,Z-and Z,E-hexadecadienyl acetate [16][17][18][19][20][21]. Athanassiou et al [22] have shown that the species can be successfully monitored by both Funnel and sticky traps, but these trapping devices provided dissimilar results, in terms of the succession of the generations.…”

The impact of trap type and height on the captures of adults of the pink bollworm, Pectinophora gossypiella (Saunders) (Lepidoptera: Gelechiidae), was assessed in cotton fields in three experimental sites (Nikaia, Nees Karyes, and Koilada) in Central Greece. Initially, the effectiveness of three different traps (white Delta, red Delta, and green Funnel) was compared. Subsequently, white Delta traps were positioned at three heights, i.e., 30, 60, and 90 cm, above ground level. Overall, captures notably increased in all traps from late July to mid-September. Funnel traps had poor performance for the captures of P. gossypiella adults, as compared with the respective figures for the other two Delta traps. Specifically, in two experimental sites (Nikaia and Koilada), both Delta traps cumulatively captured significantly more adults than the Funnel trap throughout the monitoring period. In the third site (Nees Karyes), the red Delta trap captured in total significantly more adults than the other two tested traps. Moreover, we found that traps in Nikaia placed at 90 cm captured significantly less adults as compared with the other two trap heights. The same trend was observed in Koilada; however, differences were significant only between traps at 30 and 90 cm. No significant differences were determined among different heights in the third site (Nees Karyes). These findings offer valuable insights for the monitoring protocols of P. gossypiella in cotton fields, on the basis of a standardized trapping strategy, that can take into account a wide range of factors, such as trap design and trap height.

Pink bollworm (Pectinophora gossypiella) is one of the most notorious insects causing severe damage to cotton crops thought the world. A huge amount of different chemical formulations has been used for the control of P. gossypiella population that affects its biology. The present research was executed to determine the influence of insecticides on adult fecundity and boll damage potentials by the larvae. The results elucidated that a mixture of Deltamethrin+Triazophos had a maximum impact in fecundity reduction and boll damage by the larva when tested at one, three and twenty-four hours of post-application intervals (PAI). The damage to cotton bolls was in the ranges of 27.50±0.57 to 57.50±1.44 at 3 to 144-hours PAIs respectively. Damage to cotton bolls and reduction in fecundity was at the highest 82.50±1.34, and 49.65±1.51% when a mixture of Deltamethrin+Triazophos and Alpha-Cypermethrin were applied at 144-hours PAI respectively. The experimental results highlighted the critical efficacy of the test insecticide for the control of P. gossypiella by reducing the boll damage and oviposition at different intervals of application.

“…P. gossypiella lay single white greenish eggs or a bunch of 15 or 20 eggs that change color before hatching [4]. Eggs hatch to neonate larva (2 mm) in 3-4 days with a yellowish and dark brown head, slowly attain a size of second instar (4 mm) having white color then turns to third instar (6 mm) possesses visible pink markings to appear against creamy to ivory background color [5].…”
