摘要: Proteins and saccharides are the two most important nutrients of artificial insect diets. In this study, additional protein or saccharide sources were added to the diet, and their impact on the population increase of both the prey Tyrophagus putrescentiae Schrank (Acari: Acaridae) and the predator Neoseiulus barkeri Hughes (Acari: Phytoseiidae) was investigated. T. putrescentiae population increased by 319, 317 and 180 times within six weeks, when yeast powder, glucose or sugar was added to the basic wheat bran diet (diet mass: additive mass 10:3), respectively. However, T. putrescentiae population increased by only 70 times when reared on the basic diet. All three types of nutrients resulted in increased soluble saccharide level of mixed stages T. putrescentiae. Significant increase of soluble protein level was observed when yeast powder was added. When fed on T. putrescentiae reared on yeast powder, glucose or sugar added diets, the developmental duration of N. barkeri was shortened by 23, 23 and 33%, and the daily fecundity increased by 40, 20 and 27%, respectively. The proportion of N. barkeri female offspring was 64% when fed with T. putrescentiae reared on wheat bran, increased to 70% when yeast powder was added, and decreased to 59% and 58% when glucose and sugar was added, respectively. The commercial packaging requirement of N. barkeri is 80 mites per g. It generally takes 40 days from N. barkeri inoculation to reach this requirement, but this period was dramatically shortened to 20, 25 and 24 days when yeast powder, sugar and glucose were added to the diet of T. putrescentiae, respectively.
