Abstract

北海道では,毎年約5%のダイズがハトによる被害を受けた。ダイズの栽培面積と被害面積率との間には負の相関(<i>r</i>=-0.256<sup>*</sup>, <i>n</i>=91)が,被害面積率とダイズ食害率との間には正の相関(<i>r</i>=0.390<sup>***</sup>, <i>n</i>=91)が認められた。加害の主体はキジバトであった。<br>播種時期別の被害調査(5∼6月)では,いずれも食害率が高かった。<br>畑へのハトの飛来は早朝と夕刻に多かった。<br>キジバト,ドバトとも主として植物質を餌とし,ダイズ,アズキ,コムギ,トウモロコシ,イネなどの農作物を多くとっていた。コムギは利用可能な期間が7∼9月と長く,栽培面積が急増しているために,餌としての重要性が高くなってきたと考えられる。

Damage to soybean caused by doves and pigeons was estimated to affect approximately 5% of cultivated acreage in Hokkaido from 1975 to 1977. There was a negative correlation between the acreage cultivated to soybean and the percentage of plants damaged (<i>r</i>=-0.256<sup>*</sup>, <i>n</i>=91). This damage was mainly caused by Rufous Turtle Dove. The main food of Rufous Turtle Dove and Feral Pigeon consisted of vegetables whose fragments were detected in all the gullets and gizzards examined. Crops on which Rufous Turtle Dove fed included soybean (24.1%), adzuki bean (23.1%), corn (9.4%), rice (8.9%), buckwheat (7.1%), wheat (5.3%) and oat (0.5%) and accounted for 78.4% of the bird's food in fresh weight. Crop fragments accounted for 79.8% of the gullet and gizzard contents of Feral Pigeon and consisted of adzuki bean (38.7%), soybean (29.4%), rice (7.2%), wheat (5.8%), corn (1.3%) and oat (0.1%) fragments, respectively. Of these crops, wheat is likely to become a more important source of food for Rufous Turtle Dove owing to the recent increase of acreage and availability period from July to September.
