“…In the Brazilian South‐Central region, it is considered a late pest (Oliveira et al., ); however, in the Northeast region, except for the State of Bahia, this pest attacks cotton plants during their early stages and may occur sporadically when the cotton crop reaches its maturity stage (Ramalho, ). Both, as an early and as a late pest it causes considerable production losses (Michelotto et al., ).…”

The functional response of a predator to the density of its prey is affected by several factors, including the prey's developmental stage. This study evaluated the functional response of Podisus nigrispinus (Dallas) (Hemiptera: Heteroptera: Pentatomidae) females to fourth instars and pupae of Alabama argillacea (H€ ubner) (Lepidoptera: Noctuidae), an important pest of cotton (Gossypium hirsutum L., Malvaceae) in Brazil. The prey were exposed to the predator for 12 and 24 h, and in densities of 1, 6, 12, 18, 24, and 30 items per predator female. The predation data were subjected to polynomial regression logistic analysis to determine the type of functional response. Holling and Rogers' equations were used to estimate parameters such as attack rate and handling time. Podisus nigrispinus females showed functional response types II and III by preying on larvae and pupae, respectively. The attack rate and handling time did not differ between the 12 and 24 h exposure times. Predation rate was higher at higher larval and pupal densities; predation was highest at a density of 30 prey items per female, and it was similar at 18 and 24 prey per predator. Understanding the interaction of predators and their food resources helps to optimize biological control strategies. It also helps the decisionmaking and the improvement of release techniques of P. nigrispinus in the field.

The field study was conducted during the year 2023, to study Effect of nanofertilization on the yield and its components in six cultivars of upland cotton under 5% selection intensity and to estimate the coefficient of variation for the studied traits of seed cotton yield by Effect of nanofertilization, and the cultivars are (Coker, IK30, MONTANA CHRIB-AM, 539, ALEPPO 9, CUTRUR). Seeds of the cultivars were planted in Babil Governorate using a factorial experiment according to a randomized complete block design (RCBD) with three replicates. The results of the statistical analysis showed that there were highly significant differences in the averages of the cultivars for all the studied traits, as the CHRIBAM539 cultivar excelled in the number of bolls open, bolls open weight, earlyness factor, ginning outturn percentage, seed cotton yield per plant, and plant yield (microgram hectare-1), followed by the IK30 cultivar, bolls weight, and in ginning outturn percentage (gm per plant) and the Halab 9 cultivar was superior in chlorophyll percentage, while the Coker cultivar was excelled on the seed factor, while the Cutrur cultivar was non excelled in any of the studied traits. The concentration of (2) g.L-1 of nanofertilization with half the fertilizer recommendation achieved the highest cotton yield per plant with the CHRIBAM539 cultivar, followed by the MONTANA cultivar, reaching (209.9) (173.6) respectively. Interactions between cultivars and nanofertilization with half the ground fertilizer recommendation gave highly significant differences in the number of bolls, bolls weight, seed factor, earliness factor, fiber yield, ginning outturn percentage, and seed cotton yield.
