“…One of the vital components of integrated pest management program is the utilization of resistant cultivars against insect pests (Saleem et al, 2021). Ability of insect larvae to feed on host plants efficiently suggests that there exists an inbuilt variation in plant cultivars causing antibiotic effects, antixenosis and antibiosis.…”

The chickpea pod borer Helicoverpa armigera (Lepidoptera: Hübner) is most severe insect pest in Asian countries due to its high mobility, fecundity rate and overlapping generations (Sarode, 1999). On an average, it causes 30-40% yield loss in chickpea Abstract | Pod borer (Helicoverpa armigera) is economically vital insect pests for chickpeas and caused huge yield losses in south Asian countries. Host plant resistance, physio-morphic characters counteract the ability of insect to demage and to cause minimum reduction in yield. The experiment was conducted under natural and semi-natural conditions to determine the host plant resistance of nine (09) chick pea advance genotypes viz., (K01211, K01216, K01241, K01242, K09012, KO1308, K014001, K014002, K-14003) and one (1) control (Noor). Antixenosis was calculated by counting the number of eggs per stem and antibioses was assessed by counting the number of infested leaves and survival rate of pest. The results revealed that H. armigera infestation started to appear during the second fortnight of February that continued to increase till the crop maturity. Lowest number of eggs (115) were recorded on K01308 while K09012 and K01242 were found to be most preferred for oviposition (261 and 250, respectively). Maximum larval survival about 0.98 was recorded on K09012 followed by K01216. Whereas, minimum was recorded on K014001 followed by K01308 and K014002.Minimum leaf damage percentage (1.1289%) was observed in K014001 followed by K014002, K14003 and K01308 however maximum damage (7.25%) was observed in K01242.

“…In integrated pest management program, use of insecticide remains a major control technique because it is cost-effective, efficient and easy for applying. However, use of chemicals along with reducing the number of target pests, affects the action of beneficial insects too (Wang et al, 2018;Umar et al, 2021;Saleem et al, 2021). Chemical control with Trichogramma have been measured incompatible because of the negative impact of insecticides.…”

Trichogramma (Hymenoptera; Trichogrammatidae) is a genus of parasitic wasps that are powerful biocontrol agents against a variety of insect pests. These biological control agents retain their importance due to their easy mass rearing, high searching ability and effectiveness against many crop insect pests. In this study the toxicological effect of seven insecticides viz Flubendiamide (Belt 480 SC)@ 500 ul/l, Pyriproxyfen (Priority 10.8 EC) @ 2000 µl/l, Chlorantraniliprole + Thiamethoxam (Voliam Flexi 300 SC) @ 800µl/l, Nitenpyram (Pyramid 10% AS) @ 2000 µl/l, Lufenuron (Match)@ 2000 µl/l, Chlorantraniliprole (Coragen 20% SC) @ 200 µl/l and Flonicamid (Ulala50% WG) @ 60 mg/l were evaluated on the viability of parasitized eggs, survival and parasitism efficacy of Trichogramma chilonis under controlled conditions at toxicology laboratory Entomo-

Background The chickpea pod borer Helicoverpa armigera (Hübner) is a significant insect pest of chickpea crops, causing substantial global losses. Methods Field experiments were conducted in Central Punjab, Pakistan, to investigate the impact of biotic and abiotic factors on pod borer population dynamics and infestation in nine kabuli chickpea genotypes during two cropping seasons (2020–2021 and 2021–2022). The crops were sown in November in both years, with row-to-row and plant-to-plant distances of 30 and 15 cm, respectively, following a randomized complete block design (RCBD). Results Results showed a significant difference among the tested genotypes in trichome density, pod wall thickness, and leaf chlorophyll contents. Significantly lower larval population (0.85 and 1.10 larvae per plant) and percent damage (10.65% and 14.25%) were observed in genotype Noor-2019 during 2020–2021 and 2021–2022, respectively. Pod trichome density, pod wall thickness, and chlorophyll content of leaves also showed significant variation among the tested genotypes. Pod trichome density and pod wall thickness correlated negatively with larval infestation, while chlorophyll content in leaves showed a positive correlation. Additionally, the larval population positively correlated with minimum and maximum temperatures, while relative humidity negatively correlated with the larval population. Study results explore natural enemies as potential biological control agents and reduce reliance on chemical pesticides.
