No evidence was found to indicate that the pesticides tested directly or immediately reduced predators or that predators regulated T. urticae populations in peanut plots. The fungicides benomyl and mancozeb apparently reduced the efficacy of the T. urticae fungal pathogen Neozygites floridana Weiser and Muma. T. urticae populations increased to damaging levels when the efficacy of N. floridana was reduced.}, number={4}, journal={JOURNAL OF ECONOMIC ENTOMOLOGY}, author={BOYKIN, LS and CAMPBELL, WV and BEUTE, MK}, year={1984}, pages={969–975} } @article{boykin_campbell_1984, title={WIND DISPERSAL OF THE TWOSPOTTED SPIDER-MITE (ACARI, TETRANYCHIDAE) IN NORTH-CAROLINA PEANUT FIELDS}, volume={13}, ISSN={["0046-225X"]}, DOI={10.1093/ee/13.1.221}, abstractNote={The role of wind dispersal in the ecology of Tetranychus urticae Koch in North Carolina peanut fields was evaluated. Laboratory experiments demonstrated that even low-level infestations of T. urticae were dispersed by winds of only 8 km/h. However, the most mites were dispersed by 24-km/h winds when mites were massing. In the field the number of T. urticae caught was inversely proportional to trap height, and most mites are caught at about the height of peanut plants (0.6 m). More mites were caught blowing from southerly directions along with the predominant summer winds than from any other direction; however, mites were blown in all directions. Pesticides which caused T. urticae populations to increase in peanut fields resulted in significant increases in aerially dispersing mites. Mites were dispersed by wind in all treatments, on all dates, and with all populations measured.}, number={1}, journal={ENVIRONMENTAL ENTOMOLOGY}, author={BOYKIN, LS and CAMPBELL, WV}, year={1984}, pages={221–227} } @article{boykin_campbell_1982, title={RATE OF POPULATION INCREASE OF THE TWOSPOTTED SPIDER-MITE (ACARI, TETRANYCHIDAE) ON PEANUT LEAVES TREATED WITH PESTICIDES}, volume={75}, ISSN={["1938-291X"]}, DOI={10.1093/jee/75.6.966}, abstractNote={Several commonly used pesticides were evaluated for their effect on the intrinsic rate of natural increase (rm) of Tetranychus urticae Koch on peanut to determine whether or not stimulation of mite reproductive potential by pesticides was a factor contributing to mite population increases in peanut fields. Mites fed on peanut leaves treated with mancozeb, carbaryl, and mancozeb + carbaryl had slightly, but consistently, higher rm values than mites fed on leaves from the nontreated check. Mites exposed to peanut leaves treated with ammonical copper, fentin hydroxide, benomyl, and benomyl + mancozeb + carbaryl had slightly, but consistently, lower rm values than mites exposed to the nontreated check. The data suggest that some pesticides can contribute to increased mite populations in peanut fields by stimulation of the mite’s reproductive potential, whereas other pesticides suppress mites by reduction of mite reproductive potential. Two spotted spider mites on peanut leaves exhibited a greater reproductive potential than reports in the literature for other plants. Therefore, when pesticides reduce the factors limiting populations on peanut, this reproductive potential may result in mite population increases.}, number={6}, journal={JOURNAL OF ECONOMIC ENTOMOLOGY}, author={BOYKIN, LS and CAMPBELL, WV}, year={1982}, pages={966–971} }
