Book excerpt: Abstract: One- and two-percent concentratons of lindane, carbaryl, chlorpyrifos, and chlorpyrifos-methyl were tested for their efficacy in reducing or preventing bark beetle and wood borer attacks in north Florida slash pine stands that had been treated with paraquat. Results from a series of five field experiments showed that the cumulative mortality of trees unprotected by insecticides 1 year after the indicated month of paraquat application was 63 percent (June1976), 15 percent (November 1976), 13 percent (February 1977), 83 percent (April 1977), and 40 percent (June 1977). Lindane reduced tree mortality by 50 to 100 percent whereas the other insecticides produced erratic results among experiments. Results also indicate that the season of paraquat treatment is correlated with insect infestation, tree mortality, and subsequent efficacy of insecticides. Recommendations are made for combining pest management procedures with lightwood production techniques that will result in the highest oleoresin yields.
