“…Several studies have reported that neem products also have an inhibitory effect on these EPF (Rogerio et al 2005) by suppressing the fungal growth and spore germination (Castiglioni et al 2003). The surprising effect of fungi M. anisopliae when used alone repelled the parasitoid, Aphidius colemani of Aphis fabae, but by combining with pyrethrum, it had no negative effect on the parasitoid (Fernández-Grandon et al 2020).…”

“…Metarhizium anisopliae was also considered to be synergistic when used in combination with botanicals viz. neem (Shoukat et al 2016), pyrethrum (Fernández-Grandon et al 2020), and 1-chlorooctadecane (Hussain and AlJabr 2020). The combination of pyrethrum and M. anisopliae (1 × 10 8 CFU/mL) reduced the Aphis fabae survival by 29.2 h, representing their synergistic activity (Fernández-Grandon et al 2020).…”

“…Genetic variability of fungal strains is also the reason for differential compatibility to different phytosanitary products (Mohan et al 2007). The rapid breakdown of pyrethrum and slow activation of EPF, if combined, the effect will be optimized compensating individual shortcomings (Fernández-Grandon et al 2020). It was also observed that the reduction in Agrotis segatum larval weight is due to the antifeeding effect of neem and its effect on digestive enzyme activity and biochemical composition in the midgut, prior to the attack by a virus (Elnagar et al 2004).…”

Background Entomopathogens are frequent natural enemies of arthropods worldwide, and they are capable of alternative control agents against the important pests. The optimally selected botanical product can minimize their harmful effect on these entomopathogens, and it becomes essential to know the influence of combinations of botanicals and biopesticides (botanical biopesticide combination (BBC)) in comparison to their sole action. Main body Botanicals, especially neem products, are highly efficient to be combined with the entomopathogens (with some exceptions). There are many possible reasons for the synergistic action of these botanicals, attacking the immune system of the insect being one of the important ones. These botanicals when applied in combination with microbial pesticides showed maximum sublethal effects rather than complete mortality, making them the best alternatives for combating resistance development in insects. To work effectively, biological control agents must be used within a compatible program combined with botanicals. It is highly difficult for such products to compete with chemical controls in high-value crops, so where they can become a commercially viable option in organic cultivation. The increasing acreage is under organic production for high-value export crops, where pesticide residues are undesirable for the environment, and biopesticides and botanicals are good choices for crop protection. Concerning the effect of these products used in pest control, a significant reduction in dosage in relation to the individuals is noticed. Conclusion By combining the performance and safety, biopesticides and botanicals are efficacious. This knowledge should facilitate the choice of biopesticides compatible with less harmful or naturally occurring botanicals. And if these have to be incorporated into a pest management program through an organic approach, it is necessary to determine the effects of botanicals on the beneficial microbes, on the behavior of pest, the importance of application technique, and the role of application timing for these botanical biopesticide combinations.

“…It is of global importance to survey and describe insect pathogens ( Hyde et al, 2019 ). Entomopathogenic fungi can act as natural enemies of agricultural pests and play an important role in maintaining ecological balance ( Fernández-Grandon et al, 2020 ; Sobczak et al, 2020 ). For example, fungal pathogens such as, Coelomomyces, Culicinomyces , and Lagenidium have the capacity to kill larva and adult mosquitoes, reducing their host population ( Scholte et al, 2004 ).…”

Entomopathogenic fungi are ubiquitous in tropical rainforests and feature a high level of diversity. This group of fungi not only has important ecological value but also medicinal value. Nevertheless, they are often ignored, and many unknown species have yet to be discovered and described. The present study aims to contribute to the taxonomical and phylogenetic understanding of the genus Paraisaria by describing three new species collected from Guizhou and Yunnan Provinces in China and Krabi Province in Thailand. The three novel species named Paraisaria alba, P. arcta, and P. rosea share similar morphologies as those in the genus Paraisaria, containing solitary, simple, fleshy stroma, completely immersed perithecia and cylindrical asci with thickened caps and filiform ascospores that often disarticulate at maturity. Phylogenetic analyses of combined LSU, SSU, TEF1-α, RPB1, RPB2, and ITS sequence data confirm their placement in the genus Paraisaria. In this study, the three entomopathogenic taxa are comprehensively described with color photographs and phylogenetic analyses. A synopsis table and a key to all treated species of Paraisaria are also included.

BACKGROUND The entomopathogenic fungus Beauveria bassiana and the egg parasitoid Trichogramma dendrolimi can both contribute to biological control of the global fruit borer Grapholita molesta. To derive insights for optimizing their combined application in augmentation programs, we assayed fungal pathogenicity to both G. molesta (eggs, larvae and adults) and adult parasitoids, and assessed wasp acquisition and transmission of fungal spores following their emergence from B. bassiana‐treated host eggs. RESULTS Concentrations of 108 conidia mL−1 of B. bassiana and higher caused virtually complete mortality of G. molesta larvae, but less than 30% mortality of eggs, and female moths surviving treatments had reduced fecundity. More than 80% of adult T. dendrolimi survived B. bassiana treatments of 107 conidia mL−1, and more than 60% survived 109 conidia mL−1, with surviving females achieving reproductive success equivalent to controls. Parasitoid females preferred healthy eggs over B. bassiana‐infected ones in choice tests; wasps emerging from treated eggs carried about 104 conidia each and contributed an additional 11% host mortality in trials combining both agents. CONCLUSION Our results indicate that combined applications of B. bassiana and T. dendrolimi can have complimentary impacts on G. molesta, the wasps compensating for low fungal pathogenicity to eggs and their progeny potentially aiding in subsequent disease transmission. Although foraging wasps tended to avoid infected eggs, negative interactions between the two agents might be further mitigated by timing B. bassiana applications from late instar larva to early moth stage, and T. dendrolimi releases several days later to coincide with peak oviposition periods. © 2022 Society of Chemical Industry.
