The life cycle varies from nine to more than 40 days in Australia, depending on temperature (Diagram). Summary. The total and daily production of first instars was higher in F. intonsa (90.4 and 4.2 at constant temperature, and 95.7 and 3.9 at fluctuating temperatures) than that of F. occidentalis (58.7 and 3.3 at constant temperature, and 60.5 and 3.1 at fluctuating temperatures) under both constant and fluctuating temperatures. WFT is the most prevalent species of thrips in Massachusetts greenhouses. However, time from egg to adult depends on temperature, with the optimum range between 26 and 29°C (79 and 84°F). At 25°C, it takes 13 days. Monitor routinely for thrips. It is essential that the underside of leaves and terminal buds are sprayed thoroughly since these are the areas where the thrips congregate. Identification. To compare the performance of Frankliniella occidentalis (Pergande) and native Frankliniella intonsa (Trybom) on cucumber and tomato leaves in laboratory, life history characters were investigated, and life tables were constructed using the method of age-stage, two-sex table life. Survival of immature life stages was higher under fluctuating than constant temperature for both thrips species. 2019 Sep;79(1):47-68. doi: 10.1007/s10493-019-00410-3. © The Authors 2015.
