9. Derived from:   Oatman, E. R. & E. F. Legner.  1962.  Fruit insect surveys with black light traps in Wisconsin orchards.  Entomol. Soc. Amer. North Cent. Br. Proc. 17:  2 pp.




          Black light traps used continuously throughout the 1961 growing season in a commercial apple and cherry orchard provided data on appearance, abundance, time of population peak, and seasonal distribution of the major lepidopterous pests.  There was a close correlation between species common to the two orchards except for population abundance of the codling moth, and the red-banded and fruit tree leaf rollers.  The results were similar to those obtained in 1958 and 1960 in the same orchards in respect to the appearance and seasonal distribution of each species.
