Occurrence and seasonal abundance of mite species, thrips, and spiders associated with garlic crop at Qalubia and Beni-Suef governorates, Egypt

This work deals with the occurrence and seasonal abundance of mite species, thrips and spiders associated with garlic crop at Qalubia and Beni-Suef governorates, Egypt during the 2023–2024 season. Eight mite species belonging to eight genera and seven families from four mite groups as well as one insect, Thrips tabaci Lindeman (Thripidae), were collected. Tyrophagus putrescentiae (Schrank) and Rhizoglyphus robini Claparédè (Acaridae) was the most common mite species found in all inspected materials at both locations, followed by the eriophyid bulb mite Aceria tulipae (Keifer) (Eriophyidae). Tyrophagus putrescentiae has one peak at the end of Feb. at Beni-Suef governorate; however, at Qalubia governorate, it has two peaks during mid-Dec. and mid-Feb. The bulb mite, R. robini has two peaks in mid-Nov. and late Jan. at Beni-Suef governorate; while at Qalubia governorate, it has one peck in mid-Jan. Aceria tulipae reached its peak (194.0 individuals/ cm2) late in Jan. at Beni-Suef governorate; while at Qalubia governorate, it has two peaks (193.6 and 355.5 individuals/ cm2) in late Dec. and late Feb. 2024, respectively. For the spiders, 12 species in 12 genera and six families were found on garlic plants at the two governorates. Families Philodromidae, Salticidae, and Theridiidae are the most dominant over the two governorates.
