“…The genus Pseudomonas is known to have biocontrol potential for some pest species such as leaf folder insect, Cnaphalocrocis medinalis (Commare et al 2002). Moreover, Aksoy et al (2008) indicated that P. putida had a high efficacy and caused significant amounts of mortality to two-spotted spider mites. Pseudomonas fluorescens has also been shown to control the red spider mite (Oligonychus coffeae) (Roobakkumar et al 2011).…”

“…The earliest deaths occurred within 24 h after application. The symptoms caused by Pseudomonas isolates on T. urticae were reduction of movement and the occurrence of brown-black coloration (Aksoy et al 2008). The most rapid T. urticae deaths (24 h after treatment) were obtained by Q036B which had a mortality rate of about 62% at 10 10 cfu • ml -1 concentration, while Q172B and Q110B had approximately 26 and 35% mortality rates, respectively.…”

The two-spotted spider mite (Tetranychus urticae Koch) is an important pest of many horticultural crops. A study was conducted to evaluate the effect of three fluorescent Pseudomonas isolates obtained from rhizospheric soil of tomato (Solanum lycopersicon) in Agadir, Morocco: Q110B, Q036B and Q172B, as potential biological control agents for T. urticae. Both acaricide and repellent activities were assessed on homogenous adult mites. The acaricidal activity test evaluated five concentrations of bacterial suspensions: 0 (control), 10 2 , 10 4 , 10 6 , 10 8 , and 10 10 cfu ⋅ ml -1 , while only the 10 10 cfu • ml −1 concentration of each bacterium was used for the repellent bioassay. The mortality rate and repellentindex were recorded 24, 48 and 72 h after application. Results indicated that the survival rate of T. urticae was reduced (p ≤ 0.01) by all three bacterial isolates compared to control. Within the 24-72 h time period the mortality rates ranged from 8 to 87%, 16 to 99%, and 13 to 89%, for Q110B, Q036B and Q172B isolates, respectively. The isolate Q036B (LC 50 = 0.598 cfu ⋅ ml -1 ) provided higher mortality rates than Q172B and Q110B with LC 50 values of 90,846 and 169,585 cfu ⋅ ml -1 , respectively. Repellent activity was also the highest with Pseudomonas Q036B having a 71% repellence index at 48 h after application. Regarding the mechanism of action, all three isolates produced hydrogen cyanide, and exhibited protease and cellulose activities, although only Q036B and Q172B had potential chitinase action. Identification analysis showed that the isolates were either Pseudomonas putida (Q172B) or P. fluorescens (Q110B and Q036B). Our results indicate that the P. fluorescens isolate Q036B is a promising candidate for biological control of T. urticae, and has potential to contribute to an integrated pest management program to control this important pest. Then the fruits produced will be qualified as safe for consumers and the environment. The present work was customized to give support for policy decision makers as an agroecological potential meeting needs of industries and ecological balance.

Abstract. An overview is given of diseases in mites, caused by infectious microorganisms. Many pathogens play an important role in the regulation of natural populations of mite populations and are for this reason subject of research on the feasibility to develop such pathogens to biological control agents. Several examples are given of successful application of pathogens for the control of mite pests, but also failures are discussed. Most studies concern fungal pathogens of tetranychids and eriophyids; some of these fungi are possible candidates for biological control agent of species of noxious mites. An interesting group of pathogens form the intracellular symbionts: bacteria that may cause unusual effects in their hosts, such as parthenogenesis, feminization, male killing and incompatibilities. This group of bacteria is present in many invertebrates species and are presently widely studied as new molecular techniques have become available that make detection of such symbionts possible. Attention is also given to quality control of beneficial mites that are being used in integrated control programs. Beneficial mites, as e.g. predatory mites, may also be infected by microorganisms (bacteria, viruses, microsporidia), resulting in poor performance of the predator. Prospects for the application of pathogens in IPM systems are discussed.
