“…This non-discriminatory behavior by insect parasitoids to infected and healthy hosts has also been recorded in other systems: by Fransen and van Lenteren (1993), for the parasitoid Encarsia formosa Gahan and the fungus Aschersonia aleyrodis Webber in Trialeurodes vaporariorum Westwood populations; by Furlong and Pell (2000), for the parasitoids Diadegma semiclausum (Hellen) and Cotesia vestalis (syn. plutellae) Haliday, and the fungus Zoophthora radicans in Plutella xylostella populations L.; by Mesquita and Lacey (2001) for the parasitoid Aphelinus asychis Walker and the fungus Isaria (formerly Paecilomyces) fumosorosea in Diuraphis noxia Kurdjumov populations; and by Lord (2001), for the parasitoid Cephalonomia tarsalis (Ashmead) and the fungus B. bassiana in Oryzaephilus surinamensis L. populations. As the development time of infected nymphs increased, the number of parasitized nymphs was also reduced.…”

“…Natural enemies can compete with each other for shared prey and/or hosts, numerous mechanisms have evolved that allow them, under natural circumstances, to establish spatially or temporally separate niches, and thereby coexist (e.g. Abdullah, 2008;Mesquita and Lacey, 2001;Wu et al, 2014). B. cockerelli has a large number of indigenous natural enemies (Butler and Trumble, 2012), of which the parasitoid Tamarixia triozae Burks (Hymenoptera: Eulophidae) and the fungus Beauveria bassiana, are under development as biological control agents for augmentation within IPM (Lacey et al, 2009(Lacey et al, , 2011Weber, 2013).…”

“…Interestingly, they noted that parasitoids emerging from treated hosts showed no differences in reproduction compared with parasitoids emerging from untreated hosts and concluded that both natural enemies of the whitefly are largely compatible. Field experiments on confined populations of Aphelinus asychis Walker (Hymenoptera: Aphelinidae) revealed an additive effect of I. fumosorosea and A. asychis with regard to aphid control, without any detrimental effects on the parasitism rates or parasitoid emergence when the two biocontrol agents were used together (Mesquita et al, 1997;Mesquita and Lacey, 2001). More recently, Rashki et al (2009) studied the effects of B. bassiana on the biological characteristics and life cycle of Aphidius matricariae Haliday (Hymenoptera; Braconidae) in relation to the host, Myzus persicae Sulzer (Homoptera: Aphididae).…”

“…Depending on the protagonists, their interactions may be detrimental, inconsequential or even mutually beneficial (Brooks, 1993). Some aspects of fungusparasitoid interactions have been studied, mainly in aphid hosts (Milner et al, 1984;Powell et al, 1986;Brobyn et al, 1988;Poprawskti et al, 1992;Mesquita et al, 1997;Mesquita and Lacey, 2001) and, to a lesser extent, in whitefly hosts (Fransen and van Lenteren, 1994). Despite these studies, there is a relative lack of data on the susceptibility of parasitoids and predators to entomopathogenic fungi used as mycoinsecticides under laboratory and field conditions.…”

The effect of the combined use of Encarsia formosa or Macrolophus caliginosus and one of three marketed mycoinsecticides, Mycotal® (Leucanicillium muscarium-based), Naturalis-L™ (Beauveria bassiana-based) and PreFeRal® (Isaria fumosorosea-based), on the control of the whitefly, Trialeurodes vaporariorum, was studied under laboratory and greenhouse conditions. The results of both types of tests, the bioassays and the greenhouse trials, for all combinations of E. Formosa with each of the three mycoinsecticides showed that the total mortality of larval populations of T. vaporariorum was not affected. The mortality of T. vaporariorum larvae treated in the second instar revealed the capacity for both B. bassiana- and L. muscarium-based formulations and E. formosa to kill the host either separately or in association. Because of its higher pathogenic activity (under our test conditions), L. muscarium provoked a large proportion of mycoses in larvae exposed to parasitization. In contrast, the efficacy of parasitization was higher in larvae treated with B. bassiana and exposed to E. formosa because of a lower pathogenic activity of the fungus. Bioassays carried out with third-instar larvae of T. vaporariorum showed a low susceptibility to both tested fungi. Consequently, mortalities recorded in larvae subjected to the combined treatments by consecutive exposures or at 2-4 days post-parasitization were mainly caused by the development of the parasitoid. Greenhouse trials showed that fungus-induced mortality of T. vaporariorum in plants treated with L. muscarium, I. fumosorosea, and B. Bassiana was significant compare to control. L. muscarium, B. bassiana and I. fumosorosea killed young whitefly larvae and limited parasitization to 10% or less. Second-instar larvae of M. caliginosus were not susceptible to L. muscarium and B. bassiana formulations with any mode of contamination: direct spraying of larvae, spraying on the foliar substrate or by contaminated T. vaporariorum prey. In greenhouse trials, M. caliginosus populations treated with fungi were not significantly affected compared to controls.

“…Intraguild interaction and compatibility between entomopathogenic fungi and other biological control agents of pests have been studied more with parasitoids than predators (Mesquita and Lacey 2001;Rashky et al 2009;Jarrahi and Safavi 2016). In recent studies Mohamed and Hatcher (2017) have reported that the parasitoid Aphidius colemani (Dalman, 1820) (Hymenoptera: Braconidae) and L. muscarium could be used together for M. persicae control.…”

Aphids (Hemiptera: Aphididae) are serious pests of crops causing direct damage by feeding and indirect by the transmission of plant viruses. The use of conventional insecticides for controlling aphids has caused different problems and insecticide resistance. Accordingly, there is more interest in alternative control methods such as biological control by natural enemies for sustainable agricultural management. Among biological control agents, entomopathogenic fungi are one of the most significant microbial pathogens of insects. Also, Coccinellidae, as a major group, is a serious natural enemy. Both larval and adult stages of Coccinellidae feed on different soft-body pests, such as aphids. Eriopis connexa (Germar) (Coleoptera: Coccinellidae) is a common species in agroecosystems of the Neotropical region where it is considered to be a potential control agent. Pathogens and arthropod natural enemies may contribute to the control of phytophagous pests; however, it is important to assess potential interactions within biological control agents that share hosts (intraguild interaction) to evaluate their combined use for pest control. Therefore, the aim of this study was to evaluate the compatibility and interaction (lethal and sublethal effects) between E. connexa and the entomopathogenic fungus Beauveria bassiana (Bals.-Criv.) Vuill. (Ascomycota: Hypocreales). Both are important biological control agents of aphids. The pathogenicity of B. bassiana against larvae, pupae and adults of the predator E. connexa was evaluated, and results showed, that B. bassiana infected the coleopteran. On the other hand, interaction between B. bassiana and the predator was evaluated through infected-prey. The effects of fungus on larvae survival were significantly different when we analyzed the accumulated survival (from first larval instar to adulthood). The daily fecundity was significantly reduced at five days compared to control group. By contrast, no significant differences were observed between the five oviposition days in the rate of hatched eggs. This study shows that despite having received a single dose of the fungus in its life cycle, the population parameters of the predator E. connexa are affected. More studies would be necessary to help identify interactions between microbes and natural enemies to increase and enhance opportunities and further develop biological pest control programs.
