“…Tetranychus urticae was the only pest mite collected during the two seasons and was found to be a key pest in the second season, when it occurred in greater intensity. The highest abundance of T. urticae can be attributed to the lower occurrence of its potential phytoseiid mite predators (castilho et al 2015;aBdallah et al 2019;urBaneJa-Bernat et al 2019).…”

We characterize the population dynamics of pests and beneficial organisms in strawberries to assess the impact of two meteorological factors (temperature and precipitation) and define the most appropriate method for monitoring insects in strawberries crop. Population dynamics were monitored weekly using the plant beat method and Möericke traps in Albion strawberries. Measurements were taken in organic strawberry farms over two growing seasons, from March 26, 2010 to August 23, 2010 (first season - 2009/2010) and from October 4, 2010 to March 21, 2011 (second season - 2009/2010) in the municipality of Pinhais, Paraná state, southern Brazil (25º25'S; 49º08'W). We collected a total of 7,971 pests and 1,987 beneficial organisms. The most abundant pests were Chaetosiphon fragaefolii (Cockerell) (Hemiptera: Aphididae) in the first growing season and Tetranychus urticae (Koch) (Acari: Tetranychidae) in the second. Beneficial organisms from Acari, Araneae, and Hymenoptera parasitoids predominated in both seasons. Temperature and precipitation were the the primary climatic factor associated with the population variation of aphids. Populations of C. fragaefolii grew when the temperature was between 16°C and 25ºC. We found that plant beat was the fastest and most suitable method for strawberry pests monitoring since it captured insects that were effectively colonizing the plants. This study contributes to a better understanding of the entomofauna associated with cultivation of organic strawberry.

“…Botanical pesticides from the Lamiaceae, the Asteraceae, the Myrtaceae, and the Apiaceae taxons can also be used as a complementary alternative in the control of T. urticae [ 48 ]. We can explain the increase of the number of pests during the last two weeks of follow-up by the increase in the temperature, which remains a paramount parameter for population fluctuation [ 49 , 50 ].…”

To evaluate the effectiveness of eco-friendly treatments based on detergents classified as non-hazardous and black soap on the pest Tetranychus urticae Koch 1836, and their predators (Euseius stipulatus Athias-Henriot, 1960, Typhlodromus sp., Phytoseiulus persimilis Athias-Henriot, 1957), different treatments were applied to citrus orchards planted with Valencia late (Orange) in the Mechraa Belksiri region of Morocco (T0 = control experiment; T1 = spirodiclofen 0.5 L/Ha; T2 = 125 L/Ha (5%) of black soap; T3 = detergent; 4 L/Ha of Oni product + 2 L/Ha of Tide product). The results obtained during the whole monitoring period indicated that the three treatments used, namely spirodiclofen, black soap, and detergents, ensured a reduction in the rate of population of the pest T. urticae compared to the untreated plot. In the untreated plot, the average was 45.01 A± 4.90 mobile forms, while the plot treated with spirodiclofen it was only 21.10 C ± 2.71, the black soap 31.49 B ± 3.35, and in the plot treated with detergents, the average was similar to that obtained by spirodiclofen (22.90 C ± 2.18). On the predators (E. stipulatus, P. persimilis, and Typhlodropmus sp.), the black soap and the treatment with detergents were less harmful compared to the chemical spirodiclofen.

“…It is a cosmopolitan species [2]. It presents a notable pest of field crops, ornamentals, and annual and perennial plants [5,6]; it attacks (i) fruit species, including citrus, apple, pear shrubs, and raspberry [7], (ii) vegetables, including eggplant, cucumber, bean, okra, and tomato [8][9][10][11], (iii) ornamentals, especially dahlia, rose, gerbera, zinnia, and ganda [12]; and medicinal plants, such as moringa (Moringa oleifera), metel (Datura metel), Alfalfa (Medicago sativa), Peppermint (Mentha piperita), rosemary (Rosmarinus oflicinalis), and common vervain (Verbena oflicinalis) [13,14].…”

“…In Egypt, T. urticae causes principal damage, such as defoliation, leaf yellowing, and leaf burning [14,15], plus the indirect damage by diminishing photosynthesis, transpiration, and a significant decline in yield productivity [6,16]. In Morocco, T. urticae is undoubtedly remembered for its significant damages in agriculture and its redoubtable capacity to elaborate resistance to pesticides [17]; it causes qualitative and quantitative yield losses every agricultural season.…”

“…In Morocco, T. urticae is undoubtedly remembered for its significant damages in agriculture and its redoubtable capacity to elaborate resistance to pesticides [17]; it causes qualitative and quantitative yield losses every agricultural season. All mobile stages of this mite preferentially feed on the lower surface of the leaf and extract the contents of mesophyll cells [14,18]. This pest attacks the cells of the parenchyma of which they absorb the contents with their cheliceral stylets, and provokes the appearance of yellow-greenish patches on the upper face of the leaves, thus producing the destruction of the foliage and the reduction of the period of filing of the ear [19].…”

Current Situation of Tetranychus urticae (Acari: Tetranychidae) in Northern Africa: The Sustainable Control Methods and Priorities for Future Research

In North Africa, Tetranychus urticae Koch, 1836 represents one of the most destructive generalists among mite herbivores. Unfortunately, it is a source of important annual casualties in crop production. It is a phytophagous mite that can feed on hundreds of host plants and produces significant damage. The control of T. urticae in North Africa has been principally based on acaricide sprays. However, new alternative methods have shown effective results, such as artificial ultraviolet-B, natural enemies, and the introduction of new genetic methods. This review aims to present a synthesis of information surrounding control methods of T. urticae in North Africa. We highlight the principal findings of previous studies. Then, we discuss current control methods and propose new innovative research and sustainable approaches to controlling this pest. The control method can potentially extrapolate in North African regions due to its positive ecological results. Further, studies proved the use of natural enemies, myco-metabolites, bacteria metabolites, and the introduction of a genetic method in an integrated long-term sustainable program that can successfully defeat the populations of T. urticae. We also discuss high-priority research guidelines to investigate new sustainable management strategies. Setting up an integrated long-term ecological monitoring program in different Northwest African countries and incorporating new technologies into monitoring programs is an urgent need to fight this devastating pest.
