In addition, the western flower thrips have 2 reproductive modes: arrhenotoky and sexual reproduction, which are thought to contribute to its rapid establishment, development of insecticide resistance, and adaptation to other unfavorable conditions.
Effects of Exposure to High Temperature on the Female Adult under Arrhenotoky Conditions
Under arrhenotoky conditions, the longevity of adult females of the parental generation exposed to 41[degrees]C was shortened significantly from 34.
At 25[degrees]C (control) and after an exposure to 41[degrees]C for 2 h, the longevity of adult females under arrhenotoky was significantly longer than that under sexual reproduction (control: [F.
However, under the arrhenotoky condition, these numbers were not significantly different between 2, 6, and 12 h or between 24 and 36 h of exposure.
01) and after exposure to 41[degrees]C for up to 12 h, the quantity of first progeny generation larvae was significantly higher under arrhenotoky than under sexual reproduction (2 h: [F.
Under the arrhenotoky condition, the numbers of adults in the first progeny generation were reduced from 2,483 in the control to 929 in the 36 h treatment, and the difference between treatments and the control was highly significant ([F.
