“…In cases where elimination of greening is no longer paramount, or in organic production where growers accept higher pest levels, the door opens for using more benign materials in an attempt to restore integrated pest management approaches in citrus production. Applying mycoinsecticides and insecticidal oils alone or in combination at critical flushing periods or during dormant periods could help reduce psyllid and other pest populations while having a low impact on beneficial species [ 73 , 74 , 75 , 76 , 77 ]. The effectiveness of the fungus will also depend on distribution of hosts and environmental conditions in the groves.…”

Biorational insecticides are being increasingly emphasized for inclusion in integrated pest management programs for invasive insects. The entomopathogenic fungus, Isaria fumosorosea, can be used to help manage the Asian citrus psyllid with minimal impact on beneficial arthropods, but its effectiveness may be compromised by agrochemicals used to control concurrent arthropod pests and diseases. We evaluated the compatibility of I. fumosorosea blastospores with a range of spray oils and copper-based fungicides registered for use in citrus groves. Results of laboratory and greenhouse tests showed a range of responses of the fungus to the different materials, including compatibility and incompatibility. Overall, I. fumosorosea growth in vitro was reduced least by petroleum-based materials and most by botanical oils and borax, and some of the copper-based fungicides, suggesting that tank mixing of I. fumosorosea with these latter products should be avoided. However, equivalent negative effects of test materials on fungal pathogenicity were not always observed in tests with adult psyllids. We hypothesize that some oils enhanced adherence of blastospores to the insect cuticle, overcoming negative impacts on germination. Our data show that care should be taken in selecting appropriate agrochemicals for tank-mixing with commercial formulations of entomopathogenic fungi for management of citrus pests. The prospects of using I. fumosorosea for managing the invasive Asian citrus psyllid and other citrus pests are discussed.

BACKGROUND: Nanoparticles can be used for effective pest management as a combined formulation of metal and some other material that has proven efficacy against a given pest. This study reports the synthesis, characterization and efficacy of Isaria fumosorosea-based zero-valent iron (ZVI) nanoparticles against sweet potato whitefly Bemisia tabaci (Gennadius). RESULTS:The I. fumosorosea-ZVI nanoparticles showed a characteristic surface plasmon absorption band at 470 nm during UV-visible spectroscopy. The scanning electron micrographs of nanoparticles showed spherical shaped nanoparticles with sizes ranging between 1.71 and 3.0 m. The EDX analysis showed the characteristic peak of iron at 0.6 and 6.8 KeV. The XRD analysis showed characteristic peaks at 44.72 ∘ , 65.070 ∘ , 82.339 ∘ and 82.65 ∘ . The bioassay results indicated that the percentage of larval mortality of B. tabaci challenged with I. fumosorosea ZVI nanoparticles was both concentration and age dependent. Isaria fumosorosea ZVI nanoparticles showed high pathogenicity against second and third instar nymphs, and pupae with LC 50 values of 19.17, 26.10 and 37.71 ppm, respectively. The LT 50 was lowest for second instar nymphs (3.15 days) and highest for pupae (4.22 days) when inoculated with a concentration of 50 ppm. CONCLUSION: Isaria fumosorosea ZVI nanoparticles can be an eco-friendly tool for effective B. tabaci management.

Transmission potential of the entomopathogenic fungi Isaria fumosorosea and Beauveria bassiana from sporulated cadavers of Diaphorina citri and Toxoptera citricida to uninfected D. citri adults

Diaphorina citri Kuwayama (Hemiptera: Liviidae) is the vector of the causal agent of Huanglongbing disease, and Toxoptera citricida Kirkaldy (Hemiptera: Aphididae) is the vector of the citrus tristeza virus. D. citri and T. citricida share the same habitat and both are susceptible to Beauveria bassiana and Isaria fumosorosea. Therefore, the aim of this study was to evaluate the horizontal transmission of B. bassiana ESALQ-PL63 and I. fumosorosea ESALQ-1296 between D. citri cadavers and uninfected D. citri adults, as well as between T. citricida cadavers and uninfected D. citri adults under laboratory and semifield conditions. In the laboratory, the presence of one to ten D. citri cadavers infected with B. bassiana and I. fumosorosea in citrus plants resulted in mortality rates of D. citri adults ranging from 51.2 to 81.9 % and 36.2 to 68 %, respectively. When T. citricida cadavers were used, the mortality rates of uninfected D. citri adults ranged from 35.4 to 87.7 % with B. bassiana and from 41.7 to 80.4 % with I. fumosorosea. The horizontal transmission was also confirmed under semi-field conditions. The results indicate that the control of D. citri using I. fumosorosea and B. bassiana can be promoted through conidial cycling in T. citricida, by generating new infection cycles, which may contribute to the overall performance of microbial control in citrus.
