   Sammanfattning : Pine sawflies (Hymenoptera: Diprionidae) are severe pine defoliators. This thesis investigated sawfly behaviour related to the use of pheromones in integrated pest management, including monitoring with pheromone traps and mating disruption. LÄS MER

3. 2. The effect of temperature on trophic interactions : Implications for the population dynamics of a forest pest insect in a warmer climate

   Författare :Ida Kollberg; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Increase in temperature related to climate change will have consequences on the performance of organisms. Insects could be expected to respond more than other organism groups because they are ectotherms. LÄS MER
