Behavioral Responses of a Tiny Insect, the Flower Thrips Frankliniella schultzei Trybom (Thysanoptera, Thripidae), to Atmospheric Pressure Change

摘要: How tiny insects respond to prevailing rainfall events protect themselves from water droplets is poorly known. If such could anticipate impending and take shelter avoid being hit by rain drops their chances of surviving would be increased. Some insect species can detect atmospheric pressure changes associated with accordingly. Laboratory experiments were conducted on the flower thrips Frankliniella schultzei discern whether they adjust behavior in response change. F. mating frequency seeking behaviors assessed under a range different regimes including, rapid change (50 hPa/h), designed simulate cyclonic conditions, slower rate (20 that commonly rainfall.
