Control strategies for the lucerne flea, Sminthurus viridis (L.) (Collembola: Sminthuridae), and their effect on other species in irrigated lucerne in the Hunter dairying region of New South Wales
Australian Journal of Entomology 40 (1), 79-84
Abstract: The lucerne flea, Sminthurus viridis (L.), was shown to be capable of causing significant yield loss and reductions in percentage lucerne crown cover of stands of irrigated lucerne in the temperate-type climate of the Hunter dairying region of New South Wales, an area previously considered unsuitable for lucerne flea establishment. Chlorpyrifos was used in tests of three control strategies, each of which effectively reduced lucerne flea numbers. Prophylactic sprays in autumn to prevent females of the second generation after aestivation from ovipositing gave protection for up to 3 months, but did not remove the necessity for later treatments. A single application of insecticide when lucerne flea was starting to cause severe damage was the most effective and economical control strategy but was difficult to time correctly. Some other pest and beneficial species were affected by the lucerne flea control strategies and this may have to be considered in pest management. Strategies for controlling lucerne flea were also capable of reducing numbers of redlegged earth mites, Halotydeus destructor (Tucker).
