“…Improvements in formulation of conidia have led to successes with other fungi for control of insects in less humid habitats (Bateman et al 1993;Burges 1998). Smith (1997) reviews the options for formulation of P. fumosoroseus for improved whitefly control.…”

Prior to the global outbreak of Bemisia tabaci type B in the early 1990s, very little attention was paid to the potential of fungal pathogens for control of this whitefly. A massive foreign exploration effort was mounted in 1991 by the USDA Agricultural Research Service to collect and develop fungi and other natural enemies of whiteflies. From 1990 until 1996, dozens of trips were made by scientists from the USDA European Biological Control Laboratory (EBCL) in Montpellier, France specifically for the purpose of finding natural enemies of whiteflies. The countries visited by EBCL ranged from European countries bordering the Mediterranean (Spain, France, Italy, Greece, Cyprus), to the Middle East (Israel, Egypt), Western Asia (Pakistan, India, Nepal), Southeast Asia (Thailand, Malaysia) and Latin America (Argentina and Brazil). Other exploratory efforts for entomopathogenic fungi within the USA and in other foreign countries (Philippines, Indonesia, Taiwan) were also undertaken by USDA-ARS personnel in Weslaco, Texas. The most prevalent fungus attacking B. tabaci in the field was Paecilomyces fumosoroseus. Fungi from whiteflies or from other insects with good activity against the silverleaf whitefly include Paecilomyces spp., Lecanicillium lecanii (=Verticillium), Beauveria bassiana and Aschersonia spp. Hundreds of isolates of these fungi were collected and shipped to the USA. Subsequent research involved screening of isolates for activity, study of factors that limited or enhanced their activity, and evaluation of candidate fungi in field and glasshouse crops. The literature on research for the development and implementation of these fungi is reviewed with recommendations for future avenues of research and development.

“…Other studies on M. anisopliae and the same vector showed that the effects of conidia or hyphal bodies, formulated in water, on embryos inside eggs is limited by low humidities (Luz et al , 2008; Santos et al , 2009). Oil‐based formulations of fungal propagules are known to enable infection of various insect pests at low humidities that are otherwise unfavourable for fungal development on the insect surface (Smith, 1997; Lomer et al , 2001; Luz et al , 2004) and could also increase infectivity of mosquito eggs with fungi. We report on the impact of humidity on the activity of oil‐formulated M. anisopliae on eggs of Ae.…”

The effect of humidity on the activity of Metarhizium anisopliae IP 46 (Metsch.) Sorokin (Hypocreales: Clavicipitaceae) formulated in sunflower oil against Aedes aegypti (L.) (Diptera: Culicidae) eggs was examined. After exposure of eggs at 75% relative humidity (RH) for 98% RH, eclosion was 98% RH, followed by: (a) a 12-day exposure at 75% RH before submersion in water; (b) a minimal 5-day exposure at > 98% RH and direct subsequent transfer of treated eggs to water, or (c) a minimal daily 20-h exposure at > 98% RH alternating with 4 h at 75% RH for 10 days. We demonstrate that oil-based formulations of conidia of M. anisopliae enhance ovicidal activity at high humidities and conclude that these formulations have potential in the integrated control of Ae. aegypti.
