Abstract or Summary
  • Studies to evaluate resistance in snap beans, Phaseolus vulgaris L. to adult western spotted cucumber beetles, Diabrotica u. undecimpunctata Mann. were conducted in greenhouse cages, field cages, field plots, and in temperature controlled cabinet in the laboratory. Results showed that there were differences in susceptibility to adult feeding injury between 12 selected snap bean cultivars. Spartan Arrow, Green Isle, Resistant Cherokee Wax, Itasca, and Oregon 1604 showed a higher level of resistance, whereas Blue Crop, Blue Max, Green Ruler, Bush Blue Lake, and Bush Hort. #4 were most susceptible. Beetle injury affected bean grades and damage by beetles exceeded the one percent level accepted by processors for grade A beans in all cultivars tested. Adult beetles preferred young succulent leaves of the cotyledonous stage. In all cultivars studied more than 5O% of the seedlings were damaged, however damage during the cotyledonous stage had the least effect on yield except when complete defoliation and death of seedling occurred.
