“…2). Similar results obtained by Seyed-Talebi et al (2014) who found that B. bassiana reduced reproductive potential of spider mite T. urticae where 1x10 8 of conidia suspension significantly reduced Ro, rm and e rm values from 25.68, 0.24 and 1.270 to 14.30, 0.21 and 1.24 in untreated and treated T. urticae on bean plants. Also, it was observed that P. fumosoroseus was the most harmful fungus because it highly reduced the intrinsic rate of increase rm by 35.76% comparing with untreated mites and followed by B. bassiana, M. anisopliae and C. cladosporides by reduction% of 22.62, 20.17 and 17.52%, respectively (Table 7).…”

“…Similar results were obtained by Jacobson et al (2001) who stated that Amblyseius cucumeris Oudemans was unaffected by spray of the fungi-bioagent B. bassiana (Naturalis-L). Contradicted results obtained by Seyed-Talebi et al (2014) who reviewed that the female longevity, oviposition period and fecundity of spider mite species, T. urticae were significantly lower by the subjection of B. bassiana. Wekesa et al (2006) demonstrated that the behavior of phytoseiid mites can be affected by the presence of an excessive number of conidia of the entomopathogenic fungus Neozygites floridana (Weiser and Muma) Remaudiere and Keller on Phytoseiulus longipes Evans.…”

The present study deals with the side effect of the four entomopathogenic fungi EPF, Metarhizium anisoplia (Metchnikoff), Beauveria bassiana (Balsamo), Paceliomyces fumosoroseus(Vassiljevsky) and Cladosporium cladosporiodes (Fresen), which used mainly against insect pests and spider mites, on the phytoseiid predatory mite, Cydnoseius negevi(Swirski and Amitai) in laboratory. Spore suspensions of LC50 (1x10 6 =10 6 conidia/ml) of the tested fungi, which achieved a significant reduction% in populations of the twospotted spider mite, Tetranychus urticae Koch, were sprayed on different stages of C. negevi individuals. In general, a slight negative toxic effect of EPF observed where no adverse effect was noticed on eggs while a negative effect was increasingly observed on larvae, protonymps and deutonymphs. Mortality percentage of treated adult females increased by increasing time after treatment, where the highest mortality achieved 8 days after exposure. Paceliomyces fumosoroseus had the highest rate of reduction in egg production and followed by B. bassiana then M. anisoplia, while C. cladospriodes came last. Same ranking was observed regarding the life table parameters, where LC50 of P. fumosoroseus caused the lowest Ro, rm and e rm values and prolonged the mean generation time T and doubling timeDt (days). Accordingly, in IPM program against insect and mite pests, we should use EPF as biocontrol agents, that are safe to biocontrol agents.

“…However, consideration of EPF effects should be assessed further to specify its influence on offsprings' life history, including growth, development, and reproduction (Latifian et al ., 2010). Numerous studies have been conducted for evaluating the lethal and sub-lethal effects of different EPF such as B. bassiana and Metarhizium anisopliae Metchinkoff on Tetranychus species (Wekesa et al ., 2006; Shi and Feng, 2009; Seyed-Talebi et al ., 2014; Wu et al ., 2016). However, no evidence is available regarding the sub-lethal effects of B. bassiana on the biological attributes (such as survival, longevity, fecundity, and demographic parameters) of T. urticae .…”

Tetranychus urticae (Acari: Tetranychidae) is one of the most important pests of agricultural crops with worldwide distribution causing considerable damage to different products. Application of chemical acaricides is one of the most important strategies used for the control of this pest. Entomopathogenic fungi, however, have been proposed as alternative control agents. In this study, sub-lethal effects (LC10 = 6.76 × 102, LC20 = 8.74 × 103, and LC30 = 55.38 × 103 conidia ml−1) of Beauveria bassiana strain TV on the life table parameters of T. urticae were evaluated under laboratory conditions. The results demonstrated that by increasing the concentration, a significant decline was observed in adult longevity of both male and female individuals. Total fecundity of T. urticae was calculated as 45.16, 36.28, 23.98, and 18.21 eggs in control, LC10, LC20, and LC30 treatments, respectively. Sub-lethal concentrations drastically affected the population parameters of this mite pest. The intrinsic rate of increase (r) ranged from 0.1983 to 0.1688 day−1 for the mites treated with distilled water and LC20 treatments, respectively. The net reproductive rate (R0) was affected by the sub-lethal concentrations (lower value at LC30 concentration: 11.19 offspring/individual). Considering the detrimental effects of B. bassiana on some biological parameters of T. urticae, it can be concluded that this product can be used to develop targeted interventions aimed at integrated pest management of this pest.

“…Furthermore, evidence suggests that some acaripathogens may be compatible with predatory mites and, in some cases, can have a synergistic effect [ 195 , 196 , 197 , 198 , 199 , 200 , 201 , 202 , 203 ] although negative interactions are reported [ 204 , 205 , 206 , 207 ]. Endophytic mycoacarcides may therefore play an increasingly important role in future integrated pest management systems to control phytophagous mites and reduce acaricide resistance [ 208 ].…”

Virtually all examined plant species harbour fungal endophytes which asymptomatically infect or colonize living plant tissues, including leaves, branches, stems and roots. Endophyte-host interactions are complex and span the mutualist–pathogen continuum. Notably, mutualist endophytes can confer increased fitness to their host plants compared with uncolonized plants, which has attracted interest in their potential application in integrated plant health management strategies. In this review, we report on the many benefits that fungal endophytes provide to agricultural plants against common non-insect pests such as fungi, bacteria, nematodes, viruses, and mites. We report endophytic modes of action against the aforementioned pests and describe why this broad group of fungi is vitally important to current and future agricultural practices. We also list an extensive number of plant-friendly endophytes and detail where they are most commonly found or applied in different studies. This review acts as a general resource for understanding endophytes as they relate to potential large-scale agricultural applications.
