The Same Photoperiodic Clock May Control Induction and Maintenance of Diapause in the Spider Mite Tetranchus urticae

In the spider mite Tetranychus urticae, both diapause induction (which takes place during the larval and nymphal stages) and diapause maintenance (in the adult female) are under photoperiodic control. The question of whether or not the same photoperiodic clock is involved in both photoperiodic reactions was investigated in eight strains of the spider mite, originating from different localities in Europe. The methods employed consisted of (1) determination of the relative importance of the photophase and scotophase in the two photoperiodic reactions; (2) comparison of photoperiodic response curves for diapause induction and diapause maintenance; and (3) determination of the effect of light breaks on the capacity of long nights to maintain diapause, and comparison with the effect of light breaks in diapause induction experiments. The scotophase appeared to be much more important than the photophase for both diapause induction and diapause maintenance. In all strains the critical daylength for diapause maintenance, measured at the moment of saturation of the response to long daylengths, was identical to the critical daylength for diapause induction. However, the critical daylength for diapause maintenance appeared to be labile; it shifted gradually to shorter values as the mites were kept in the cold for a longer period of time, or were kept at a higher temperature for a progressively longer period of time after their stay in the cold room. This seems to reflect a gradual loss of photoperiodic control of diapause maintenance as diapause development proceeds. Photoperiods close to the critical daylength appeared to be less strong with regard to diapause maintenance than shorter daylengths. Quantitative differences in the "strength" of different daylengths were found in all strains investigated. Interruption of the night by short pulses of light revealed either one or two peaks of sensitivity in the night, or one broad "trough" where the two peaks had merged. However, in each case maximal sensitivity to the light breaks occurred at the same position in the night for diapause induction and diapause maintenance. The many similarities found lead to the conclusion that most probably the same photoperiodic clock mechanism is involved in both diapause induction and diapause maintenance in T. urticae.

“…Cumulative data have shown that in long-day type pests, diapause is prevented by (1) light breaks adequately placed at night, and (2) extension of the light phase (Ankersmit 1968;Beach and Craig 1979;Berlinger and Ankersmit 1976;Hayes et al 1970Hayes et al , 1974aHayes et al , b, 1979Sáringer 1982Sáringer , 1983. Unfortunately, such measures have not been developed further since it is economically difficult to obtain sufficient light intensity in the field.…”

Effects of extending the light phase on diapause induction in a Japanese population of the two-spotted spider mite, Tetranychus urticae

et al. 2007

Artificial lighting is a merit of a 'plant factory', which might be utilized to suppress an increase in pest population. We investigated the effects of extending the light phase on diapause induction in the two-spotted spider mite (TSSM), Tetranychus urticae. TSSM were reared at 18 degrees C under light phases ranging from 2 to 64 h combined with a constant dark phase of 16 h in aluminum bottles, with white light emitting diodes attached inside to minimize fluctuations in air temperature between the light and dark phases. Diapause was induced in adult TSSM females when the light phase was 24 h or shorter, and diapause induction was inhibited when the light phase extended over 32 h. The development of deutonymphs was delayed under a diapause-inducing photoperiod. Diapause inducing photoperiods may suppress an increase in the TSSM population, by slowing down development and reproduction.

“…Lighting could be used to prevent diapause induction by interrupting the night or by extending the daylength [ 16 ]. Many studies have shown that photoperiodic manipulation can prevent diapause in the tortricid moth Adoxophyes orana [ 35 , 36 ], European corn borer Ostrinia nubilalis [ 37 , 38 , 39 , 40 ], codling moth Cydia ( Laspeyresia ) pomonella [ 37 , 40 , 41 , 42 ], tobacco budworm Heliothis virescens [ 41 ], pink bollworm Pectinophora gossypiella [ 41 , 43 ], oak silk moth Antheraea pernyi [ 41 ], rock pool mosquito Aedes atropalpus [ 44 ], and turnip sawfly Athalia rosae [ 45 ]. The artificial extension of daylength through the use of fluorescent tubes or mercury vapor lamps has prevented diapause of O. nubilalis and C. pomonella in the field [ 36 , 39 ], but such measures have not been developed further, probably because achieving sufficient light intensity in the field is too costly.…”

Integrated pest management (IPM), which combines physical, biological, and chemical control measures to complementary effect, is one of the most important approaches to environmentally friendly sustainable agriculture. To expand IPM, we need to develop new pest control measures, reinforce existing measures, and investigate interactions between measures. Continued progress in the development of environmental control technologies and consequent price drops have facilitated their integration into plant production and pest control. Here I describe environmental control technologies for the IPM of spider mites through: (1) the disturbance of photoperiod-dependent diapause by artificial light, which may lead to death in seasonal environments; (2) the use of ultraviolet radiation to kill or repel mites; and (3) the use of water vapor control for the long-term cold storage of commercially available natural enemies. Such environmental control technologies have great potential for the efficient control of spider mites through direct physical effects and indirect effects via natural enemies.
