【摘要】 1991年5～7月在山东省沂南县沂河林场杨树人工林内,定期枝条取样和收集虫粪分析昆虫种类组成及数量变动。利用油毡巢箱,采用雏鸟扎颈法收集大山雀雏鸟食块230个。繁殖期大山雀以昆虫育维,5月份以柳紫闪蛱蝶的蛹和幼虫数量较多,每窝雏鸟平均消耗1377.6个食块,每公顷内真实消耗量为1294.9个食块。6月份的雏鸟食物以毒蛾和白杨透翅蛾成虫为主,窝平均消耗和每公顷内消耗量分别为1002.2个和310.8个食块。7月份的雏鸟食物种类较丰富,窝平均消耗为1383.3个食块,每公顷消耗量为864.7个食块。更多还原

【Abstract】 Nestling food composition and consumption of great tits (Parus major Linnaeus) in the Poplar plantation was studied using 230 preys collected from the nestling crops at Yihe Forest Farm, Yinan County, Shandong Province during May to July in 1991. The average food consumption amounted to 1377.6 preys per clutch and 1294.9 preys per ha in May, 1002.2 preys and 310.8 preys in June, 1383.3 preys and 864.7 preys in July. Based on the nestling food composition, the food selection of breeding great tits was discussed preliminarily combining with the sample data of insects taken from the branches and frass in the Poplar plantation. Changes in insect species and numbers showed changes in diet from May to July. More pupae and larvae of Apatura metis Freyer were found in May, more adults of Lymantridae and Parathrene tabaniformis Rottenberg in June, and more insect species in July.更多还原
