Performance of each species was determined by comparing single-visit pollen deposition, percentage of visits that contacted the s...
متن کاملPollination Services Provided by Bees in Pumpkin Fields Supplemented with Either Apis mellifera or Bombus impatiens or Not Supplemented

متن کاملElectroantennogram responses of Chrysoperla carnea (Stephens) to volatiles.
Electrophysiological responses of adult males and females of C. carnea to commonly occurring plant volatiles were recorded using the electroantennogram technique. Responses to 28 volatiles evaluated indicate that both depolarization and recovery to the baseline were rapid in females compared to males. Normalized EAG responses relative to the standard, trans-caryophyllene reveal significant diff...
