“…Il cause de graves dégâts sur nombreuses cultures (Takafuji et al, 2000). Les acaricides synthétiques ont été largement utilisés pour contrôler ce ravageur dans les vergers, sous serres et dans d'autres systèmes de production ce qui a conduit à l'apparition de la résistance (Van Leeuwen et al, 2006). En effet, de nombreuses espèces d'insectes et d'acariens ont développé la résistance à une ou plusieurs classes de produits phytosanitaires synthétiques (Van Leeuwen et al, 2009).…”

The use of botanical acaricides extracted from plants as an alternative to replace the chemical acaricides is an interesting and efficient option to control pests and ameliorate their toxic effects to humans and the environment. The aim of this work was to evaluate the contact toxicity of Pennyroyal mint (Mentha pulegium), oregano (Origanum compactum) and thyme (Thymus capitatus) essential oils against adults, larvae and eggs of two-spotted spider mite Tetranychus urticae Koch (Tetranychidae). The chemical composition of these three plant essential oils was also characterized. Laboratory tests were conducted to determine the acaricidal effect of plant essential oils at several doses in geometric progression. The consequences of treatments on mortality were measured in relationships with concentrations of essential oils. On the other hand, the major constituents of the three essential oils were identified by gas chromatography-mass spectrometer (GC-MS) techniques. GC-MS analyses proved that the major compound present in the essential oils of thyme and oregano is carvacrol (55.59 and 55.28% respectively) while the main component of pennyroyal mint essential oil is pulegone (67,63%). Laboratory bioassay results indicated that essential oils of thyme and pennyroyal mint caused the most important acaricidal effects in comparison with the essential oil of oregano. At a concentration of 1%, thyme and pennyroyal eradicate all adults of the mite while oregano causes a mortality of European Scientific Journal January 2018 edition Vol.14, No.3 ISSN: 1857 -7881 (Print) e -ISSN 1857-7431 119 84.99%. On larvae, the mortality rate of thyme, pennyroyal and oregano is 97.7; 89.47 and 57.89% respectively. The results of the present study concluded that plant essential oils could be useful in promoting research aiming at the development of new agent for pest control from the plants with medicinal values.Keywords: Tetranychus urticae-Mentha pulegium-Origanum compactumThymus capitatus-essential oils RésuméL'usage d'acaricides botaniques extraits à partir des plantes comme alternatives aux acaricides chimiques est une option intéressante et efficace pour contrôler les ravageurs et améliorer leurs effets toxiques sur les humains et l'environnement.

“…When such mutants are easily detectable and do not differ in life history relative to the wild strain, they provide an excellent system to monitor the invasion success of different behavioral phenotypes in a novel context. We used a pesticidesensitive strain of the two-spotted spider mite Tetranychus urticae, of which a mutant has been selected that exhibits strong maternally inherited pesticide resistance (Van Leeuwen et al 2006). This strong resistant phenotype was shown to be caused by mutations in cytochrome b, a mitochondrially encoded protein in the respiratory pathway (Van Leeuwen et al 2008).…”

Abstract. Dispersal is essential for population persistence in transient environments. While costs of dispersal are ubiquitous, individual advantages of dispersal remain poorly understood. Not all individuals from a population disperse, and individual heterogeneity in costs and benefits of dispersal underlie phenotype-dependent dispersal strategies. Dispersing phenotypes are always expected to maximize their fitness by adaptive decision making relative to the alternative strategy of remaining philopatric. While this first principle is well acknowledged in theoretical ecology, empirical verification is extremely difficult, due to a plethora of experimental constraints. We studied fitness prospects of dispersal in a game theoretical context using the two-spotted spider mite Tetranychus urticae as a model species. We demonstrate that dispersing phenotypes represent those individuals able to maximize their fitness in a novel, less populated environment reached after dispersal. In contrast to philopatric phenotypes, successful dispersers performed better in a low density post-dispersal context, but worse in a high density philopatric context. They increased fitness about 450% relative to the strategy of remaining philopatric. The optimization of phenotype-dependent dispersal, thus, maximizes fitness.

“…However, using pesticides for a long time causes an ecological imbalance, side effects on natural enemies, and environmental pollution (Stumpf & Nauen 2002;Kim et al 2004). Besides, T. urticae has a high potential of breeding and its short life cycle facilitate its resistance against acaricides (Stumpf & Nauen 2001;Van Leeuwen et al 2006).…”

Tetranychus urticae Koch (Acari: Tetranychidae) is a harmful pest for crops such as vegetables, fruits, and ornamental and industrial plants. The usage of plant extracts for pest control is seen as an alternative to synthetic pesticides. The effect of methanolic extracts obtained from sage (S. officinalis) and rosemary (R. officinalis) plants from the Lamiaceae family on T. urticae was researched in an effort to create an alternative to synthetic pesticides. The spray tower-leaf disk method was used to determine the acaricide effects of these plant extracts. The effect of sage and rosemary extracts on the pest's eggs, in nymph and adult stage was examined in the research. Four different concentrations of the plant extracts, which were 1%, 3%, 6% , 12%, were examined. The trials were prepared such that each concentration had 4 repeats and each repeat included 15 individuals. Death-live counts were made on the 1 st , 3 rd and 6 th days. The highest death rates of T. urticae at nymph and adult stages were found at 12% concentrations of sage and rosemary extracts. At this concentration, the death rate for nymph and adults was found to be 79% and 62.2% for sage extract and 58% and 82.2% for rosemary extract. The ovicidal effect of sage and rosemary extracts on pests was determined at the same concentration. As a consequence, sage and rosemary extracts are thought to be used as an alternative method to pesticides for mite control.
