Overwintering behaviour of Tetranychus telarius (L.) in the Stanthorpe district, Queensland

Bengston, M. (1965) Overwintering behaviour of Tetranychus telarius (L.) in the Stanthorpe district, Queensland. Queensland Journal of Agricultural and Animal Sciences, 22 (2). pp. 169-176.



A single polyphagous strain of Tetranryclms telarius (L,) is present in the Stanthorpe district. On deciduous hosts this mite enters the non-feeding winterform, while on evergreen hosts it persists as the active two-spotted form. Nutritional factors are decisive in inducing the winterform. Photoperiod is of only slight importance. The winterform could be induced to feed and to commence egg-laying at any time and is considered to represent a quiescence rather than a true diapause. Data on the survival of the winterform under controlled temperature conditions were in general agreement with field observations that only a small percentage of these individuals successfully overwinter in the Stanthorpe district.
