If not, it may be better to locate and disrupt breeding sites, using aerial spraying.

如果不是，那么最好是利用飞机喷雾对它们的繁殖点进行定位和破坏。

Soran Ahmed said, " Places like Bamo mountain, if effectively protected, could become a breeding site for the leopards."

索兰·艾哈迈德说：“像巴莫山这样的地方，如果得到有效保护，可能会成为波斯豹的繁殖地。”

Fewer fledglings were leaving the breeding site together, which reduced their chances of surviving their first winter at sea.

可以结伴离开繁殖地的幼鸟数量更少了，这降低了它们在海上活过第一个冬天的机会。

They are “muscling in and getting the first claim on breeding sites”, says Richard Cowser of the Sussex Ornithological Society.

据苏塞克斯鸟类学社团的理查德 考瑟所说，它们“强势插入，占领繁殖地。”

The breeding sites duly dried up.

繁殖地适当地干涸了。

The guidelines say, “Larviciding should be considered for malaria control -- with or without other interventions -- only in areas where the breeding sites are few, fixed and findable.”

指导方针称，“不管有没有其他干预办法，只有在那些繁殖地很少、固定且容易发现的地区，杀幼虫剂才能被视为疟疾控制的办法。”
