• Control of Ctirus Thrips by Avermectin

      Rethwisch, M. D.; Butler, Marvin (College of Agriculture, University of Arizona (Tucson, AZ), 1988-12)
      Two rates of Avermectin were mound- applied; one treatment of Avermectin B one of Carzol were applied by air to citrus in April for control of citrus thrips. Plots were sampled by beating new terminal growth and counting thrips. Ground applications had fewer thrips than applications made by air. Avermectin B1 treatments had significantly fewer thrips than Carzol at all sample dates.
    • Update on Fuller's Rose Beetle in Arizona

      Rethwisch, M. D.; Sumner, C.; Butler, Marvin (College of Agriculture, University of Arizona (Tucson, AZ), 1988-12)
      Initial studies of Fuller rose beetle (FRB) biology have found some adult emergence in late June and early July. No adults woe found in foliage in May or early June, nor was activity noted in August and early September. FRB were not found in early October, but they began expected major emergence in mid-October. Several FRB collected did not have fused wings, atypical for this species. This finding suggests flight ability in FRB, currently unknown to occur.
