“…(Hypocreales: Cordycipitaceae), Beauveria. asiatica Rehner and Humber, and Metarhizium brunneum Petch (formerly M. anisopliae (Metschnikoff) (Hypocreales: Clavicipitaceae) are under development for control of ALB (Goble et al 2014(Goble et al , 2016Meng et al 2015;Clifton et al 2020a). Beauveria brongniartii has already been developed into a commercial product in Japan, and M. brunneum is available for commercial use in the US, both inducing high mortality rates (Brabbs et al 2015, Clifton et al, 2020a.…”

Preventing invasions of Asian longhorn beetle and citrus longhorn beetle: are we on the right track?

Two Asian longhorn beetles, Anoplophora glabripennis and Anoplophora chinensis are among the most serious alien invasive species attacking forest and urban trees, both in North America and Europe. Major efforts have been put into preventing further entry and establishment of the two species as well as promoting their successful eradication. Here we review these efforts, their progress and outcome, and scientific advancements in monitoring and control methods. The combined international activities and harmonizing legislative changes in detection and eradication methods have proven worthwhile, with more than 45% of eradication programmes successful in the last 12 years. Some countries were able to completely eradicate all populations and others managed to reduce the area affected. Although the costs of the eradication programmes can be very high, the benefits outweigh inaction. Attempts to eradicate A. chinensis have been more challenging in comparison with those targeting A. glabripennis. For both species, efforts are hampered by the ongoing arrival of new beetles, both from their native regions in Asia and from other invaded regions via bridgehead effects. The methods used for eradication have not changed much during the last decade, and host removal is still the method most commonly used. On the other hand, detection methods have diversified during the last decade with advances in semiochemical research and use of detection dogs. The next decade will determine if eradications continue to be successful, particularly in the case of A. chinesis, which has been targeted in some countries for containment instead of eradication.

“…These drawbacks necessitate a hydromulch formulation to increase water retention capacity, maximalize conidial production and viability, and reduce the effect of external weather modifiers. Hydromulch is a wetter condition than the surrounding air after spraying or rain can experience evaporation reducing conidial production, and when the surrounding air is wetter condensation will soak the hydromulch with moisture and increase the conidial production again [21].…”

Entomopathogenic fungi have seen application in pest control due to being more friendly to the environment compared to synthetic insecticides. This research aims to determine the potentials of entomopathogenic fungi by identifying research reports regarding the effectiveness of fungi as biological agents for controlling pest insect attacks on forest plants. This research used a systematic review to enable extended analysis. The systematic review was performed on secondary data obtained from 51 scientific articles concerning tests of entomopathogenic fungi on forest plants pest insects. The research publications originated from multiple continents and a surge in the number of publications took place in 2020. Curculionids were the most frequently found pest insects with 14 species encountered. The most frequently found and tested stadium of insects on the field was the adult stage used in 39 researches. The most dominant fungi used in the researches were ascomycetes with 31 species, ten species among them originating from the Cordycipitaceae family. The most used application methods were direct spraying and immersion, each with a 33% percentage of usage.

“…Some studies highlighted that this fermentation approach enables considerable yields in terms of fungal biomass and metabolites such enzymes (Higuchi et al, 1997; Jenkins & Lomer, 1994; Kumar & Singh, 2001; Osma et al, 2011). Reporting on this subject can be grouped into two kinds: (1) direct growth on the surface of a semi‐solid medium and subsequent use of propagules as biocontrol agents (Feng et al, 1994; Lopes et al, 2019; Mejía Maldonado et al 2020; Villamizar et al, 2021), and (2) fungal bands, which fungi grow on inert fabrics to use directly in the field (Carolino et al, 2014; Costa et al, 2017; Dubois et al, 2004; Goble et al, 2016; Hakeem et al, 2016; Higuchi et al, 1997; Jenkins & Grzywacz, 2000; Shimazu, 2004; Ugine et al, 2013).…”

Aims The leaf‐feeding pest Cerotoma arcuata tingomariana (Bechyné) (Coleoptera: Chrysomelidae) produces huge economic losses in different crops. This study aimed to produce conidia by semisolid‐state fermentation and to establish the insecticidal activity of two formulation prototypes based on a native Beauveria bassiana isolate for controlling this pest. Methods and results A novel fabric‐based semisolid‐state fermentation strategy for quick and large‐scale conidia production was performed and characterized. Conidia were formulated as an emulsifiable concentrate (EC) and a water‐dispersible granulate (WG). Afterwards, the mortality of C. a. tingomariana adults was assessed. A conidia concentration of 2.9 × 109 conidia cm−2 was obtained after 9 days‐course fermentation and a yield of 33.4 g kg−1 dry‐substrate. Conclusions The polyester fabric‐based fermentation is an efficient technique for producing and collecting B. bassiana spores. Regarding LC90, the potency analysis showed that the EC was 21‐fold more potent than the non‐formulated conidia, and ~ 2.6‐fold more potent than the WG. Significance and impact of study A high throughput fermentation based on polyester fabric as support for B. bassiana conidia production and subsequent formulation as an EC comprises a promising strategy for obtaining a bioproduct to control adults of C. a. tingomariana and other Chrysomelidae pests.
