“…Oligonychus afrasiaticus (McGregor) is a widespread species of spider mites infesting the fruits of date palm in Middle East (Saudi Arabia [ 2 ], Oman [ 3 ], Iraq [ 4 ], Iran [ 5 ], Egypt [ 6 ], Israel [ 7 ], Yemen [ 8 ]), and North Africa (Tunisia [ 9 ], Algeria [ 10 ]). The infestation of old world date mites starts after fruit set and multiply logarithmically on the kimri stage of the fruit by spinning silken webs around date bunches [ 11 ].…”

Current study reveals the likelihood to use pathogen and toxin mutually as an effective and eco-friendly strategy for Oligonychus afrasiaticus (McGregor) management, which could reduce toxicant dose and host killing time. Therefore, phytol and Beauveria bassiana in different proportions were evaluated to determine their effectiveness. Prior to ascertaining host mortality and defense mechanisms, we have recorded in vitro action of phytol using different concentrations (0.70, 1.40, 2.10, 2.80, and 3.50 mg/mL) against B. bassiana suspension. In vitro compatibility assays revealed that growth parameters (vegetative growth, sporulation, and viability) of B. bassiana were least affected by the action of phytol at all tested concentrations. Biological Index of B. bassiana exhibited compatibility with phytol allowed us to conduct Joint toxicity bioassays in which phytol and spores mixed in different proportions in order to attain maximum treatment effect in terms of high mortality at low concentration under short time. Results revealed that joint-application exhibited both synergistic (treatments with higher proportions of phytol), and antagonistic interaction (treatments with higher proportions of spores) interactions. Biochemical mechanisms involved in host antioxidant and detoxification response were explored by quantifying their respective enzymatic activities. Lethality of different treatments induced different patterns of detoxification enzymes including glutathione S-transferase (GST) and acetylcholinesterase (AchE). Overall, the least potent treatments (20% phytol:80% spores, and 40% phytol:60% spores) established in the current study induced relatively higher GST and AchE activities. On the other hand, the most potent treatment (80% phytol:20% spores) at its maximum concentration exhibited negligible relative GST and AchE activities. Antioxidant enzyme activities of CAT and SOD measured in the current study showed moderate to complex interaction might because of toxin-pathogen remarkable synergy. This study suggested that joint application of phytol with B. bassiana spores have shown tremendous acaricidal potential and found to be promising new strategy for controlling old world date mites.

“…This causes large damage and lead to economic losses (Taha et al, 2019). In Iraq, O. afrasiaticus caused within 50-80% produce loss of dates within years on dry, dusty and stormy weather (Al-Jboory and Al-Suaide, 2010). The date palm dust mite, O. afrasiaticus has become an important pest of immature date palm fruits on Sewi variety at the New Valley Governorate in Egypt.…”

“…Several researchers have been investigated the biology of O. afrasiaticus, under different environmental condition and biotic factors (Ba-Angood and Bass'haih, 2001;Al-Sweedy et al, 2006;Al-Jboory and Al-Suaide, 2010;Ben Chaaban et al, 2011;Ben Chaaban et al, 2012;and Elhalawany 2013).…”

Entomology Journal publishes original research papers and reviews from any entomological discipline or from directly allied fields in ecology, behavioral biology, For several years the palm dust mite, Oligonychus afrasiaticus (McGregor) has been an economically important pest of date palm. Biology and life table parameters of the date dust mite, O. afrasiaticus were studied on fronds of three date palm cultivars: Bartamoda (dry), Sewi (semi dry) and Zaghlol (soft) at laboratory conditions of 30 and 35°C & 60 ±5% R.H. and 16L. The results revealed that, the longest and shortest oviposition period and total longevity of O. afrasiaticus females were recorded at 30°C (22.5 & 26.90 days) on Sewi and 35°C (6.9 & 10.0 days) on Zaghlol variety, respectively. The fecundity increased as temperature decreased from 30.5, 37.45 and 25.5 eggs at 30°C to 27.8, 29.15 and 15.94 eggs at 35°C on Bartamoda, Sewi and Zaghlol varieties, respectively. The lowest and highest values of the intrinsic rate of increase (r m ) were 0.107 and 0.229 individuals/female/day that obtained at 30 and 35°C on Zaghlol and Sewi varieties, respectively. The mean generation time (T) significantly decreased from 23.6, 22.4 and 22.76 days to 13.08, 11.90 and 12.26 days with increasing temperature from 30°C to 35°C, on Bartamoda, Sewi and Zaghlol varieties, respectively. The results of this study indicate that O. afrasiaticus could increase rapidly when Sewi and Bartamoda fronds serve as a food source more than Zaghlol date palm variety.
