Pyrethroid-resistant onion thrips, Thrips tabaci Lindeman (Thysanoptera: Thripidae), infesting persimmon fruit
A total of 53 strains of onion thrips, Thrips tabaci Lindeman, were established, of which 14 strains were collected from persimmon fruit and 39 strains from a vetch weed, Vicia angustifolia, in commercial persimmon orchards in Wakayama Prefecture. Susceptibility to insecticides was evaluated by the Petri dish-spraying tower method. Pyrethroid-resistant strains and pyrethroid-susceptible strains...
متن کاملAdvances in control of onion thrips (Thysanoptera: Thripidae) in cabbage.

J. Econ. Entomo!. 75: 492-494·(1982) Studies conducted to determine Thrips tabaci Lindeman damage and contamination in sauerkraut revealed that both occur at detectable levelsin processedcabbage, althoughsuch levelsare much lower than predicted from examination of fresh cabbage. Addition of the chemical preservativessodium benzoate (0.1%) and potassiummetabisulfite (0.05%) had no effect on plan...
متن کاملDevelopment and Use of a Dynamic Sequential Sampling Program for Onion Thrips., Thrips tabaci (Thysanoptera: Thripidae)., on Onions
J. Econ. Entomol. 80(5): 1051-1056 (1987) ABSTRACT Data collected in 1983 from six commercial onion fields in upstate New York indicate that dispersion characteristics of onion thrips (OT), Thrips tabaci Lindeman, are precisely described by Taylor's power law (S2 = amb), with Ina = 0.517, SIn, = 0.059, b = 1.89, and Sb = 0.028 (n = 47; r2 = 0.99: P :$ 0.0001). Additionally, during the main peri...
متن کاملConsequences of co-applying insecticides and fungicides for managing Thrips tabaci (Thysanoptera: Thripidae) on onion.
BACKGROUND Insecticides and fungicides are commonly co-applied in a tank mix to protect onions from onion thrips, Thrips tabaci Lindeman, and foliar pathogens. Co-applications reduce production costs, but past research shows that an insecticide's performance can be reduced when co-applied with a fungicide. An evaluation was made of the effects of co-applying spinetoram, abamectin and spirotetra...
