“…A single application of B. bassiana (1 × 10 8 spores•mL − 1 ) suspensiom after the release at low rate of the phytoseiid predatory mite, Phytoseiulus persimilis Athias-Henriot (10 prey:1 predator) successfully controlled T. urticae Koch population (P < 0.001), with the lowest corrected leaf damage (1.5%) on bean plants (Ullah and Lim 2017). The effectiveness of B. bassiana combined with Purpureocillium lilacinum Thom (1910) (Hypocreales, Ophiocordycipitaceae) TR1 was reported on T. urticae by Yeșılayer (2018) who recorded a mortality rate of 66.6% at the highest doses (10 8 conidia•mL − 1 ). In the Table 1, more information is depicted about the control programs that successfully used B. bassiana for crop protection from 2009 to 2019.…”

Background: For controlling the resistance to insects, in particular carpophagous and phyllophagous caterpillars, using chemical pesticides has led to contamination of cotton area in Benin. Facing this problem, alternative methods including the use of entomopathogenic fungi as biopesticide could be a sound measure to preserve the environment, biodiversity and ensure good quality of crops. Previous studies have revealed the insecticidal potential of the entomopathogenic Beauveria bassiana on some insect pest species. However, little is known about its effectiveness on cotton Lepidopteran pests. This review is done to learn more about B. bassina for its application in controlling cotton insect pests, especially Lepidopteran species. Main body: Different sections of the current review deal with the related description and action modes of B. bassiana against insects, multi-trophic interactions between B. bassiana and plants, arthropods, soil and other microbes, and biological control programs including B. bassiana during last decade. Advantages and constraints in applying B. bassiana and challenges in commercialization of B. bassiana-based biopesticide have been addressed. In this review, emphasis is put on the application methods and targeted insects in various studies with regard to their applicability in cotton. Conclusion: This review helps us to identify the knowledge gaps related to application of B. bassiana on cotton pest in general and especially in Lepidopteran species in Benin. This work should be supported by complementary laboratory bioassays, station and/or fields experiments for effective management of cotton Lepidopteran pests in Benin.

“…have not been found to infect mites naturally ( Wekesa, Hountondji & Dara, 2015 ), and they do not cause natural epizootic diseases in mites, some isolates of B. bassiana and M. anisopliae have been shown to be infective to T. urticae under laboratory conditions, when inoculated in greenhouses, or in the field. This is suggestive of their potential to control this pest ( Alves et al, 2002 ; Bartkowski, Odindo & Otieno, 1988 ; Chandler, Davidson & Jacobson, 2005 ; Draganova & Simova, 2010 ; Bugeme et al, 2014 ; Bugeme et al, 2015 ; Dash et al, 2018 ; Yesilayer, 2018 ).

Background The mite Tetranychus merganser is considered to be an emerging pest of various crops in tropical countries. It is one of the most detrimental pests in the papaya orchards of some regions of México. The current field control of Tetranychus spp. involves the extensive use of chemicals that have some degree of toxicity to humans or the environment and may cause selective resistance. The use of biological alternatives such as parasitoids and mite predators have limited effectiveness. In order to find effective but non-toxic alternatives for mite pest management, bio-products that are able to be mass produced and applied to large production areas have been sought, including the entomopathogen fungi. B. bassiana and M. anisopliae s.l. are the fungi most extensively used for the biological control of insect pests. Although they do not cause natural epizootic diseases in mites, there are reports that show that they infect T. urticae, and should be evaluated for use in the biological control of papaya’s mite pests. Methods A T. merganser colony was established and the susceptibility of adult females to 30 entomopathogenic fungi strains was evaluated under laboratory conditions with an in vitro mass screening bioassay. Ten strains of Metarhizium anisopliae sensu lato (s.l.), eleven of Beauveria bassiana, nine of Lecanicillium sp. and one of Hirsutella thompsonii var. sinematosa were tested. The infectivity of adult females was evaluated calculating the percentage of mortality. To calculate the LC50 and LT50 of the most virulent strains, a bioassay was performed using serial concentrations (1×104–1×108 conidia/mL) for each strain. Strains showing ability to infect eggs laid were evaluated with a novel egg-infectivity bioassay. The internal transcribed spacer (ITS) region of the more lethal strains were sequenced. Results T. merganser and T. urticae were found in orchards of Carica papaya (Maradol variety and Tainung hybrid) in Campeche, México. All tested strains of M. anisopliae s.l. and B. bassiana were infectious to the adult female of T. merganser at a concentration of 1×108 conidia/mL. Six strains of M. anisopliae (Ma002, Ma003, Ma004, Ma005, Ma014 and Ma034) caused 100% mortality, and one of B. bassiana (Bb016) caused 95% mortality. The most virulent was Ma034, with an LC50 of 1.73×106 conidia/mL followed by Ma005 and Ma003. Ma005 and Ma034 were the fastest strains to reach LT50,achieving this in less than 3.7 days. Additionally, Ma034 and Ma014 strains were infectious to more than 70% of the eggs. Conclusions T. merganser and T. urticae are present in the papaya orchards of Campeche, México. The high susceptibility of T. merganser adult females and eggs toward several M. anisopliae s.l. or B. bassiana strains suggests that these fungi are a viable alternative to control this emergent pest. The most virulent strain, Ma034, was also infective to eggs, and is the most promising to be tested in the field.

“…[1][2][3] This mite feeds on the sap of plants affecting photosynthetic capacity; severe infestations can result in severe defoliation. [4][5][6][7] Resistance to 96 pesticide active ingredients has been reported in ≥526 separate cases, all resulting from indiscriminate pesticide application against T. urticae populations. 8 With cases of acaricide resistance growing, and with public awareness of negative effects on human health and contamination of soil and water by synthetic pesticides, other control methods are urgently needed and the subject of ongoing research.…”

BACKGROUNDMost studies on efficacy of fungal pathogens and predatory mites against Tetranychus urticae have been done on individual species in the laboratory. We evaluated fungi and predatory mites separately and together against greenhouse populations of T. urticae on chrysanthemum plants. First, effectiveness of the fungal pathogens Beauveria bassiana (Bb88) and Metarhzium anisopliae (Ma129), was compared; then, effectiveness of the predatory mites Phytoseiulus persimilis and Neoseiulus californicus. Based on the results, N. californicus and isolate Ma129 were selected and evaluated in combination. In all experiments, treatment effects were assessed for eggs and motile stages of T. urticae.RESULTSThe first experiment showed no significant effect of both fungal isolates on T. urticae populations, except on plants initially infested with 20 mites, where more eggs were found in the control compared to the fungal treatments. In the second experiment, both predatory mites were equally effective at reducing T. urticae populations compared with the control, regardless of initial T. urticae population density. The last experiment demonstrated that populations of T. urticae were reduced most when M. anisopliae (Ma129) and N. californicus were applied together, compared with the control and when each natural enemy was applied separately.CONCLUSIONSM. anisopliae (Ma129) and B. bassiana (Bb88) isolates did not have a significant effect reducing T. urticae populations. Both predatory mites reduced T. urticae populations, regardless of T. urticae density. Combined application of M. anisopliae (Ma129) and N. californicus were more effective against T. urticae than the control or when each agent was applied separately.This article is protected by copyright.
