It has been shown that pollen as a dietary supplement may increase the establishment of generalist predatory mites, and therefore pest control by these mites can be provided. Life table studies were performed to evaluate the nutritional value of seven different pollens (almond, castor-bean, date-palm, maize, bitter-orange, sunflower and mixed bee pollen) as a supplementary food source for the spider mite predator Neoseiulus californicus McGregor. In addition, the nutritional quality of each pollen species was assessed through morphological and chemical analysis.
Preadult duration was longer when the predator fed on castor-bean pollen (10.01 days) and bee pollen (9.94 days) compared with the others (5.58-7.27 days). The cohort reared on almond pollen had the highest intrinsic rate of increase (r) (0.231 day ), and those on mixed bee pollen had the lowest r (0.005 day ). The levels of nutritional content (sugar, lipid and protein) were significantly different among tested pollens.
Comparison of N. californicus life table parameters on different diets revealed that the almond pollen (and after that the maize pollen) was a more suitable diet than the others. These findings will be useful in developing appropriate strategies for conservation of N. californicus to control spider mites. © 2016 Society of Chemical Industry.
研究表明，花粉作为一种膳食补充剂可能会增加多食性捕食螨的数量，从而实现这些螨类对害虫的控制。进行了生命表研究，以评估七种不同花粉（杏仁、蓖麻、枣椰、玉米、苦橙、向日葵和混合蜂花粉）作为叶螨捕食者加州新小绥螨麦格雷戈补充食物来源的营养价值。此外，通过形态学和化学分析评估了每种花粉的营养质量。
与其他花粉（5.58 - 7.27天）相比，捕食者取食蓖麻花粉（10.01天）和蜂花粉（9.94天）时，未成熟期更长。以杏仁花粉饲养的种群内禀增长率（r）最高（0.231天⁻¹），而以混合蜂花粉饲养的种群内禀增长率最低（0.005天⁻¹）。受试花粉之间的营养成分（糖、脂类和蛋白质）水平存在显著差异。
对加州新小绥螨在不同食物上的生命表参数进行比较后发现，杏仁花粉（其次是玉米花粉）比其他花粉更适合作为食物。这些发现将有助于制定合适的策略来保护加州新小绥螨以控制叶螨。© 2016化学工业协会。
