１９９５年作者进行了田间试验来比较模拟的条纹黄瓜甲虫 Ａｃａｌｙｍｍａ Ｖｉｔｔａｔｕｍ（Ｆ）脱叶作用及实地Ａ．ｖｉｔｔａｔｕｍ脱叶作用对‘Ｃａｒｏｌｉｎａ’黄瓜光合反应的影响。在５个生长阶段（从第一片真叶到收获）中，共模拟了６种脱叶水平（０％一１００％）。在每一生长阶段，每点植株每周两次用剪子去叶，这一处理叫连续脱叶。除此之外，对同一生长阶段植株也用了一次性脱叶处理，但只有４种脱叶水平（０，２５，５０及１００％）。用Ａ．ｖｉｔｔａｔｕｍ成虫笼养试验来估计实地害虫脱叶危害。每笼中甲虫放置时间为两周，密度各为每株０，１，３，５及１０头，测定其净光合速率。在模拟及实地害虫脱叶处理之间，没有测到显著的光合速率差异（ Ｐ＞０． ０５）。在模拟害虫脱叶试验中，受损叶片和未受损叶片的光合速率也很少有显著差异。结果显示模拟害虫脱叶处理过程不仅能准确反映实地Ａ．ｖｉｔｔａｔｕｍ脱叶危害下的‘Ｃａｒｏｌｉｎａ’黄瓜的生长反应，而且也适用于确定Ａ．ｖｉｔｔａｔｕｍ对黄瓜的经济危害水平。
In 1995, the authors conducted field trials to compare simulated leaf defoliation and field A of striated cucumber beetle Acalymma Vittatum (F). Effects of Vittatum Leaf Exfoliation on Photosynthesis of ’Carolina’ Cucumber. In five growth stages (from the first true leaf to harvest), a total of six leaf defoliation levels (0% to 100%) were simulated. At each growth stage, plants are defoliated with scissors twice per week. This treatment is called continuous defoliation. In addition, one-off defoliants were used for the same growth stage but only four levels of defoliation (0, 25, 50 and 100%). Use A. Vittatum adult cage test to estimate the hazards of pests in the field defoliation. The beetle was placed in each cage for two weeks with 0, 1, 3, 5 and 10 densities per plant. The net photosynthetic rate was determined. No significant differences in photosynthetic rate were observed between simulated and field pest defoliation treatments (P> 0.05). In simulated pest defoliation experiments, there was also no significant difference in photosynthetic rate between damaged and non-damaged leaves. The results showed that simulated pest defoliation treatment process can not only accurately reflect the field A. The growth response of ’Carolina’ cucumber, which is endangered by vittatum, also applies to determination of A. vittatum on the economic harm of cucumber levels.
