“…In general, these effects are strongly related to fungal dosage and the sequence of treatments. Lower fungal dosages and application of the arthropod natural enemy first reduced negative effects of entomopathogenic fungi on ladybird beetles (James et al 1995;Pingel and Lewis 1996;Todorova et al 1996;Roy and Pell 2000;Smith and Krischik 2000;Pell and Vandenberg 2002;Roy et al 2008), lacewings (C. carnea) (Portilla et al 2017), and several aphid parasitoid species (Brodeur and Rosenheim 2000;Mesquita and Lacey 2001;Kim et al 2005;Aqueel and Leather 2013;Oreste et al 2016;Shrestha et al 2017). Likewise, infection of prey and the time interval between fungal application and predator/parasitoid release may also affect the number of aphids consumed by the predator or the number of parasitoid mummies that may develop (Mesquita and Lacey 2001;Aqueel and Leather 2013;Ibarra-Cortés et al 2018).…”

Bottom-up effects of endophytic Beauveria bassiana on multitrophic interactions between the cotton aphid, Aphis gossypii, and its natural enemies in melon

et al. 2019

Entomopathogenic fungi are now known to have an endophytic capacity that induces a wide range of changes in the composition of plant nutrients and/or defensive compounds. These changes could influence interactions between the plant and higher trophic levels. In this study, we evaluated the predation/parasitism efficacy of larvae of the lacewing, Chrysoperla carnea, and the braconid parasitoid, Aphidius colemani, when offered aphids that had been challenged by the entomopathogenic fungus Beauveria bassiana. Aphids were either inoculated directly with a fungal suspension (lacewing bioassay only) or had been feeding on melon plants endophytically colonized by B. bassiana. Our results indicate that B. bassiana application did not significantly influence the number of aphid prey consumed by lacewings, or the time took them to consume each aphid. In a choice bioassay, C. carnea larvae preferred to feed on aphids reared on B. bassiana-colonized plants compared with control plants. In another choice assay, the number of aphids parasitized by A. colemani and their sex ratio were not influenced by whether the aphids had been feeding on B. bassiana-colonized plants or not. Our findings support the hypothesis that endophytic entomopathogenic fungi can be used in combination with other natural enemies, such as predators and parasitoids, in Integrated Pest Management programmes.

“…The American authorized strain NI8 B. bassiana, which was isolated from tarnished plant bug, Lygus lineolaris, can infect various insect predators including H. axyridis, but with LC 50 values of 3- to 90-fold those of L. lineolaris [ 34 ]. In contrast, the same isolate had significant effects on adults of Chrysoperla rufilabris [ 35 ] and low effects on H. axiridis , Orius insidiosus , H. convergens and C. maculata [ 36 ]. Moreover, there are differential susceptibility among coccinellid species to EPF.…”

This study aimed to estimate the virulence of an indigenous Beauveria bassiana on all developmental stages of two indigenous coccinellids; Coccinella undecimpunctata and Hippodamia variegata through three application methods; direct spray, contact method, and feeding on aphids treated with the fungus (ingestion). Also, indirect effect on all developmental stages resulted from 1st larval instar treated with these application methods. All treatments were done with a concentration of 1 × 105 which was recommended in previous studies for different aphid species with a control of 0.02% Tween 80 (v/v). The mortality of 1st larval instar of both H. variegata and C. undecimpunctata and pupal stage of C. undecimpunctata were significantly increased with spray method only. Also, contact method achieved significantly higher mortality on 1st larval instar of C. undecimpunctata only. Regard to indirect effect, except of mortality of 1st larval instar of both predators and 2nd larval instar of H. variegata, other developmental instars/stages of both predators were not affected by B. bassiana through the three tested application methods in the mortality, duration, survival, cumulative survival male and female longevity, and fecundity. Therefore, both tested predatory coccinellids could be compatible with this indigenous isolate of B. bassiana where, in general, there are no negative effects of the fungus on both predators.

“…In the case of fungi, as in that of other pest control agents effectiveness is measured by its virulence and in other cases by its lethality, however, the efficiency of a control agent on its target could be subject to many more conditions, since it is known that not all insects treated with a fungal agent necessarily they will die immediately after application (Gandarilla-Pacheco et al, 2015). This phenomenon has been called sublethal effects or late effects at different stages of the mosquito life cycle which gives them a selective advantage over other agents similar to them (Mnyone et al, 2011;Pelizza et al, 2013;Portilla et al, 2017). These effects are considered relevant because in insects such as Ae.…”

Late effects of Beauveria bassiana on larval stages of Aedes aegypti Linneo, 1762 (Diptera: Culicidae)

et al. 2022

Aedes aegypti is a culicide that has gained relevance over the years due to its ability to transmit various viruses that cause diseases in humans that all the years cause high mortality rates in the world population. The main problem is that Ae. aegypti has managed to establish and maintain a close relationship with humans and their habitat, which is why the search for alternatives to control vector populations becomes imperative. The objective of the present work was to study the effects of two Beauveria bassiana strains on Aedes aegypti. Third instar larvae of Ae. aegypti in 250 mL plastic containers were inoculated with the GHA and NB3 strains at different concentrations (1.5 × 104, 1.5× 105, 1.5 × 106 and 1.5 × 107 conidia/mL). The NB3 strain presented highest mortality values with 63% in the highest concentration i.e., 1.5 × 107, while for the GHA strain the highest mortality value was 30.7% at the same concentration. The results showed significant difference in mortality with respect to the strain and days post treatment (P = 0.0001), but not with respect to the conidial concentration (P = 0.634). The average mortality of larvae per day for the NB3 for different concentrations ranged from 20 to 25 larvae per day, while for the GHA daily mortality ranged from 5 to 12 larvae. In post-treatment mortality, the highest mortality was recorded in the third stage larvae for the NB3, while for GHA the highest percentage mortality was observed in individuals who managed to reach the adult state. The findings of the current research depicted the noteworthy role of B. bassiana for the management of an important vector of human disease.
