Fuchs, T.W. and J.A. Harding. 1976. Seasonal abundance of arthropod predators in various habitats in the lower Rio Grande valley of Texas. Environmental Entomology, 5(2): 288-290.

Abstract

Arthropod predators in various habitats were sampled weekly with a D-Vac® vacuum insect collector during 1973–75 in the Lower Rio Grande Valley of Texas. Data indicate that non-cultivated habitats support larger numbers of predators/unit area than do cultivated habitats. Over 50% of all predators collected were spiders. The mixed grasses habitat supported the greatest average number of predators/sample. (Emphasis added.) A sharp decline in predator numbers occurred during the summer season in all habitats sampled.
