Abstract/Contents: | Sampling techniques for larvae of Herpetogramma licarsisalis (Wlk.) were studied in turf grass in Hawaii. Sprinkling 1 litre of 0.0015% pyrethrins or 0.25% detergent into a 1860-cm2 frame forced 61 and 55%, respectively, of the larvae to the surface, as compared with the numbers for 4 litres of the irritants (the commonly used amount). Continuous observation was required during the 10 min after application, since 29% of the surfaced larvae reentered the thatch within 5 min, and 38-39% reentered within 10 min. The detergent forced more than 50% of the larvae to surface within 2 min, as compared with 4 min for pyrethrins. Liquid irritants brought about 3 times as many larvae to the surface in 5-10 min than plywood set out overnight. The same techniques were found to be satisfactory for Spodoptera mauritia (Boisd.), Hylephila phyleus (Dru.) and Agrotis ipsilon (Hfn.). |
