“…Persistent infection deforms fruit and inhibits the growth of plants. Adaptive strategies of the mite are based on high fecundity of females and a femalebiased offspring sex ratio, which can lead to rapid population increases (Carey and Bradley 1982). When populations surpass an economic threshold, the use of synthetic acaricides is a requisite tool for T. urticae control.…”

In the pursuit of developing effective bio-acaricidal agents, the toxicity by residual contact and repellency of the essential oils (EOs) of Origanum compactum, Mentha piperita and Artemisia herba-alba and their mixtures against adults of Tetranychus urticae was investigated. The oils demonstrated repellency and toxicity to mites based on dose. Combinations of the EOs in binary and ternary forms had antagonistic and additive effects on the mite's toxicity and repellency, with the exception of combined O. compactum and M. piperita EOs that displayed a synergistic acaricidal relationship. The chemical composition of the oils was identified via GC/MS analysis; major constituents were thymol (49%) in O. compactum, linalool (45.81%) in M. piperita and camphor (25.08%) in A. herba-alba. Further, we evaluated the acaricidal activity of secondary metabolites produced by Pseudomonas species using cell-free supernatants, and reported on the mode of entry of Pseudomonas supernatants into adult mites. The bioactive acaricidal compounds were most effective (57.6 to 96.1% mortality) when the entire integument of T. urticae was contacted compared to the ventral side only (15.3 to 80.7%). The toxicity of the most active bacterial supernatant was investigated at 1/2, 1/4 and 1/8 dilutions in combination with the EOs. The combinations synergistically killed the mite. Lethal effects were seen 72h after exposure. Bio-acaricidal formulations may take use of synergistic combinations to manage the two-spotted spider mite.

The effects of six ambient temperatures (15, 20, 25, 30, 35 and 37.5ºC) on life table parameters of Tetranychus kanzawai Kishida (Tetranychidae) were studied under laboratory conditions on soybean (Glycine max (L.) Merrill). Total immature developmental time of females at the above-mentioned temperatures was 28.55, 16.34, 9.01, 6.96, 5.56 and 5.65 days, respectively. A linear and two nonlinear models of Lactin and SSI were fitted to developmental rate of immature stages of T. kanzawai to predict the developmental rate as a function of temperature, as well as to estimate the thermal constant (k) and critical temperatures. The estimated k for total immature developmental time of females and males was 134.58 and 126.74 DD, respectively. The estimated Topt and Tmax by Lactin model for overall immature stages were 36.20 and 40.70ºC, respectively. Intrinsic optimum temperature (TФ) and T1 (Topt) by SSI model for total immature stages was estimated to be 23.23 and 35.71ºC, respectively. Also the estimated TL and Th of SSI model for overall immature stage were 09.21 and 38.46ºC, respectively. The longest and shortest adult longevity was observed at 15°C (60.63 days), and 37.5°C (7.34 days), respectively. Mated females laid highest and lowest eggs at 25°C (237.96 eggs) and 37.5°C (30.54 eggs), respectively. The rm values ranged from 0.356 day-1 at 30°C to 0.089 day-1at 15°C. The highest value of R0 was 163.55 offspring female-1 at 25°C. The presented information in this study provided new perspective to better management of T. kanzawai on apple trees in Iran.
