“…25 However, assays of compatibility are required before specific agents can be used in joint applications, as inappropriate combinations of EPFs and parasitoids can produce antagonistic effects that could potentially reduce biocontrol efficacy. 60,61 Although T. dendrolimi emergence from B. bassiana-infected eggs was reduced in the present study, the parasitism efficiency of the resulting females was not different from those emerging from control eggs, nor was their fitness in terms of progeny number and sex ratio. Adult T. dendrolimi emerging from host eggs treated with B. bassiana spores each carried ca.…”

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.

“…Concurrent use of these fungi and parasitoids might work in a synergistic or antagonistic manner (Roy and Cottrell 2008) to enhance control D. saccharalis, but further research is required to clarify the nature of their interactions when co-occurring in the same host (Santos et al 2006;Rossoni et al 2014aRossoni et al , 2014bIbrahim 2015). This fact motivated us to investigate whether B. bassiana and M. anisopliae compromise the development of P. elaeisis, T. howardi, and T. diatraeae in pupae of D. saccharalis.…”

Development of Eulophidae (Hymenoptera) parasitoids in Diatraea saccharalis (Lepidoptera: Crambidae) pupae exposed to entomopathogenic fungi

Palmistichus elaeisis Delvare and LaSalle, Tetrastichus howardi (Olliff), and Trichospilus diatraeae Cherian and Margabandhu (Hymenoptera: Eulophidae) are promising candidates for the control of sugarcane borer, Diatraea saccharalis (Fabricius) (Lepidoptera: Crambidae). The fungi Beauveria bassiana (Balsamo) Vuillemin (Cordycipitaceae) and Metarhizium anisopliae (Metchnikoff) Sorokin (Clavicipitaceae) also can be used to control sugarcane borers plus leafhoppers (Hemiptera: Cercopidae) in sugarcane. This observation motivated us to investigate whether entomopathogenic fungi can affect biological aspects of these parasitoids. Diatraea saccharalis pupae (24 hours in age) were exposed to parasitism by three females of each eulophid species for 72 hours and then placed in small tubes. A contact surface treated with 1 mL of fungal suspension was placed inside each tube with the parasitised pupae at concentrations of 1×109, 5×109, or 10×109 conidia mL−1 of M. anisopliae and B. bassiana. Exposure to fungi reduced emergence of adult P. elaeisis, but not of T. howardi and T. diatraeae. Life cycle duration, progeny, and sex ratio of P. elaeisis were not affected by exposure. Exposure was associated with decreased longevity for both sexes of T. howardi and in males of P. elaeisis, but not at levels expected to affect their performance as biocontrol agents. In general, the exposure of eulophid species developing in pupae of D. saccharalis exposed to entomopathogenic fungi, did not compromise the biological aspects of these parasitoids.

The knowledge on ovigeny in parasitoids is important for basic studies on physiology and applied biological control. The ovigeny pattern and type of ovariole of the parasitoid Palmistichus elaeisis Delvare & LaSalle (Hymenoptera: Eulophidae) were studied in newly-emerged females at seven, 14, 24 and 48 h intervals after their emergence from Tenebrio molitor L. pupae (Coleoptera: Tenebrionidae). Females of P. elaeisis presented ovaries composed by four ovarioles of the meroistic polytrophic type. The yolk accumulation and chorionogenesis in P. elaeisis were concluded 24 h after the female emergence. The 48 h-old females show a high quantity of egg ready for oviposition. These findings can help to improve the mass production of P. elaeisis and the augmentative biological control by using this natural enemy.
