“…A similar decrease in chlorophyll was observed in T. urticae-injured peppermint leaves, which was proportional to the injury sustained (De Angelis et al, 1983). Chlorophyll loss was proposed to result from cell disruption and the removal of chloroplasts rather than the enhanced metabolic degradation or decreased synthesis of chlorophyll; however, the possibility that mite-induced water stress influenced chlorophyll metabolism was not discounted (De Angelis et al, 1983). The extent of the decrease in ehloronhvll content in mite-injured leaves ~enerallv (Tomczyk and Kropczyfiska, 1985).…”

Chlorophyll fluorescence and leaf chlorophyll content of bean leaves injured by spider mites (Acari: Tetranychidae)

The use of chlorophyll fluorescence as a method for detecting and monitoring plant stress arising from Tetranychus urticae (Koch) feeding injury was investigated. The effect of mite density (1-32 mites per 1.5 cm z of leaf) and the duration of the feeding period (1-5 days) on the chlorophyll fluorescence parameters of bean (Phaseolus oulgaris) leaves were examined. Changes in chlorophyll fluorescence parameters were dependent both on mite density and duration of feeding. Decreases in Fo, the initial fluorescence and Fro, the maximum fluorescence led to a decrease in the ratio of variable to maximum fluorescence, Fv/F m. The decrease in FJF m is typical of the response of many plants to a wide range of environmental stresses and indicates a reduced efficiency of photosystem II (PSII) photochemistry. 7"1/2, which is proportional to the pool size of electron acceptors on the reducing side of PSII, was also reduced in response to mite-feeding injury. The leaf chlorophyll content decreased with increasing mite density and duration of feeding but did not appear to contribute to the decrease in Fv/F m. Chlorophyll fluorescence is an effective method for detecting and monitoring stress in T. urticae-injured bean leaves.

“…This injury indicates chloroplast destruction. Thus, reductions in chlorophyll content are usually associated with T. urticae injury when visible damage is present (DeAngelis et al, 1983;Welter, 1989;Campbell and Marini, 1990;Bondada et al, 1995). Little attention has been paid so far to event that happens early at the beginning of infestation or when the level of infestation is low.…”

“…Injury caused by T. urticae is very severe and nowadays most fields are treated with acaricides such as clofentezine, hexythiazox, fenbutain oxide and tetradifon to control the pest (DeAngelis et al ., 1983;Morris et al ., 1996). To find an alternative control method we assessed the effect of pyrrolizidine alkaloids (PAs) extracted from Lithospermum canescens on the biology of the two-spotted spider mite.…”

In this study we assess the effect of pyrrolizidine alkaloids (PAs) extracted from Lithospermum canescens on the biology of the two-spotted spider mite (Tetranychus urticae Koch). Lithospermum canenscens (Michaux) Lehm. (Boraginaceae) is a common prairie plant also known as Indian paint or hoary puccoon. A mixture of seven PAs with known chemical structures was used in this investigation. Mites treated with PAs showed a high mortality of juveniles, a decrease in female fecundity and a shortened longevity. The intrinsic rate of population increase (r(m)) was used as an indicator of T. urticae population performance after treatment with PAs. The r(m) value obtained with alkaloid-treated leaves was lower than that for mites developing on untreated leaves, which indicates that the mite population would develop much slower on treated plants. The results suggest that further studies should be performed to assess the possible use of PA extracts for spider mite control.
