(Lepidoptera: Scythrididae): Short-term effect of tillage system. Rev. Colomb. Entomol. [online]. 2023, vol.49, n.1, e11487.  Epub Jan 03, 2023.

Syringopais temperatella Led. (Lepidoptera: Scythrididae) is a serious threat of barley and wheat in Jordan. There is a growing interest in the development of innovative control strategies to minimize the environmental impact of pest management. Little attention has been paid to the use of cultural control methods against the pest, accordingly, this study aimed at investigating the effect of tillage system in controlling S. temperatella. The study was conducted in Karak Governorate during the 2019-2020 cropping season with four tillage types, i.e., 1) no-tillage, 2) moldboard, 3) disk and 4) chisel plows. Three soil depths (15, 30 and 45 cm) were evaluated for each plow type. Data on the Mutah barley cultivar’ infestation percentage, number of larvae, plant height, grain yield weight, straw biomass, and soil moisture were recorded. Our findings emanate from a one-year analysis under semiarid conditions, sandy-clay loam soils and low soil moisture in a barley monocrop system using 2 m2 plot size with 3 replicates. Results revealed that pest infestation and number of larvae were significantly lower in moldboard plow followed by disc plow and chisel plow, and then in no-tillage. Pest infestation and number of larvae decreased significantly with increasing plowing depth. Plant height, grain yield, straw biomass and soil moisture were significantly higher when the moldboard plow was used, followed by chisel plow, disc plow, and then no-tillage; likewise, they increased significantly with increasing tillage depth up to 45 cm.
