Experiments were carried out in July, September, October 1993 and January 1994 on 48 dead pigeons kept in cold storage (refrigerating machine) and at a window. The behaviour of Mallophaga was observed. The insects left the feather after the cooling of the bird body, usually after 24 hours. The process lasted 3 days in cold storage conditions, while in outdoor (open-air) environment the Mallophaga were still alive for another 14 days. The vitality of Mallophaga is bigger in open-air, in moderately higher temperature and in warmer seasons of the year. The examined representants of three species dominating in infestation demonstrated varying suitability for survival in harder conditions. The reaction of Hohorstiella gigantea lata (PIAG.) to the drop of temperature was the fastest, while Columbicola columbae columbae (L.) reacted more slowly and the reaction of the Campanulotes bidentatus compar (BURM.) was the slowest. Also the reaction of larvae to falling temperatures was faster that that of the adult forms.
1993年7月、9月、10月以及1994年1月，对冷藏于冷库（制冷机）和窗边的48只死鸽进行了实验。观察了食毛目昆虫的行为。在鸟体冷却后，通常是24小时后，这些昆虫离开了羽毛。在冷藏条件下，这个过程持续3天，而在户外（露天）环境中，食毛目昆虫还能再存活14天。食毛目昆虫在户外、温度稍高以及一年中较温暖的季节里活力更强。所检查的在侵扰中占主导地位的三个物种的代表在更恶劣条件下的生存适宜性各不相同。巨型霍氏羽虱（PIAG.）对温度下降的反应最快，而鸽鸽羽虱（L.）反应较慢，双齿细羽虱（BURM.）的反应最慢。幼虫对温度下降的反应也比成虫更快。
