Physiological responses of Corythucha ciliata adults to high temperatures under laboratory and field conditions.

摘要: Abstract Under high temperature conditions, insects can tolerate to survive through various physiological mechanisms, which have been well documented in laboratory studies. However, it is still unclear as whether these data scale up those the field. Here we studied dynamics of heat-induced metabolites Corythucha ciliata adults under both and field conditions examine their significance thermal tolerance species. We compared effects controlled treatments (2 h at 33–43 °C 2 °C intervals laboratory) naturally increasing (10:00–14:00 2-h (33.5–37.2 °C) on a hot summer day Shanghai, China) water content levels water-soluble protein, triglycerides, mannitol, sorbitol adult bodies. The results showed that significantly decreased all other metabolic parameters increased response stresses with similar patterns field, although respective threshold temperatures were different two conditions. close linkage observed suggests short period heat stress induces loss accumulation C. adults. This heat-resistance provides defense mechanism counteracting damage ciliata.
