Aerodynamic advantages of upside down take-off for aerial dispersal in Tetranychus spider mites

Abstract: Aerial dispersal may be important for redistribution of spider mites into new habitats. Evidence for behavioral control of aerial take-off has been well documented for Tetranychus urticae Koch. Before aerial dispersal they exhibit the aerial take-off posture that involves lifting the forelegs upright and raising the forebody. However, whether the aerial take-off posture functions to increase drag has remained unclear. The objectives of this study were to clarify: (i) aerodynamic effects of the aerial take-off … Show more

“…Although it has been well documented that departure-specific behaviours affect the likelihood of aerial dispersal of spider mites 19, 32 , there has been no empirical evidence that similar behaviours in eriophyoid mites promote the probability of their becoming airborne or being picked up by vector organisms. Melo et al .…”

“…However, its long dorsal setae are seemingly not essential for aerial dispersal because spider mites with short dorsal setae, such as Tetranychus urticae Koch and T. kanzawai , also disperse aerially (Smitley and Kennedy 1985; Osakabe et al 2008). Although adult P. citri females with long dorsal setae appeared to be well defended against predatory mites, juvenile P. citri with shorter setae may have less protection against predators.…”

“…Wind dispersion is common among mite species, and can be favoured by behaviours and postures that prepare the mite for take‐off and dispersal . The lifting of body parts in spider mites (tetranychids), eriophyids,and phytoseiids, and the production of structures such as silk threads that allow ballooning or roping in spider mites are behaviours commonly associated with (passive) wind dispersal of mites. Exposure to acaricides can affect these behaviours, which may interfere with take‐off.…”
