“…The development of insecticide resistance in the cockroaches is a serious problem in control of these insects. New insights were focused on the effects of the use of the entomopathogenic fungi Beauveria bassiana (Balsamo) Vuillemin and Metarhizium anisopliae (Metschnikoff) Sorokin (Ascomycota, Hypocreales) against Blattella germanica L. (Blattodea: Blattellidae) and Periplaneta americana (L.), evaluating their virulence and host range (Murali Mohan et al 1999, Quesada Moraga et al 2004, Lopes and Alves 2011. Previously, authors reported studies on the evaluation of B. bassiana effects on B. germanica (Pachamuthu et al 1999, Zurek et al 2002; other reports were related to virulence, transmission, and differential susceptibility of nymphs and adults of B. germanica to M. anisopliae (Quesada Moraga et al 2004, Lopes andAlves 2011).…”

Differences in free fatty acids (FFAs) chemical composition of insects may be responsible for susceptibility or resistance to fungal infection. Determination of FFAs found in cuticular lipids can effectively contribute to the knowledge concerning insect defense mechanisms. In this study, we have evaluated the susceptibility of three species of cockroaches to the entomopathogenic fungi Metarhizium anisopliae (Metschnikoff) Sorokin by topical application. Mortality due to M. anisopliae was highly significant on adults and nymphs of Blattella germanica L. (Blattodea: Blattellidae). However, mortality was faster in adults than in nymphs. Adults of Blatta orientalis L. (Blattodea: Blattidae) were not susceptible to the fungus, and nymphs of Blaptica dubia Serville (Blattodea: Blaberidae) were more susceptible to the fungus than adults. The composition of cuticular FFAs in the three species of cockroaches was also studied. The analysis indicated that all of the fatty acids were mostly straight-chain, long-chain, saturated or unsaturated. Cuticular lipids of three species of cockroaches contained 19 FFAs, ranging from C14:0 to C24:0. The predominant fatty acids found in the three studied species of cockroaches were oleic, linoleic, palmitic, and stearic acid. Only in adults of Bl. orientalis, myristoleic acid, γ-linolenic acid, arachidic acid, dihomolinoleic acid, and behenic acid were identified. Lignoceric acid was detected only in nymphs of Bl. orientalis. Heneicosylic acid and docosahexaenoic acid were identified in adults of Ba. dubia.

“…German cockroaches are primarily controlled through the use of synthetic organic insecticides (organophosphates, pyrethroids, and carbamates), but many factors including insecticide resistance, concerns about human and environmental safety, and increased developmental cost of new insecticides have intensified the search for new control methods. One potential alternative is the use of biologically based insecticides, such as those containing entomopathogenic fungi (Kaakeh et al, 1996(Kaakeh et al, , 1997Murali Mohan et al, 1999).…”

Rhynchophorus ferrugineus, commonly referred to as red palm weevil (RPW), is an invasive Indian sub-continent pest that infests date palms in the Arabian peninsula and dates-growing countries. In an effort to manage red palm weevil infestations, exotic isolates of entomopathogenic fungi, especially Metarhizium anisopliae were procured from different sources for possible use against red palm weevil larvae. In this study, we evaluated the virulence attributes including the viability and relative hydrophobicity of the spores of M. anisopliae isolates 8453, 7234 and 406; and their impact on the host susceptibility, growth and antioxidant defense. Results indicated that isolate 8453 had 20.64 % higher relative hydrophobicity compared with the least virulent isolate 406 that showed the highest LT 50 value (10.90 days). The feeding performance experiment revealed significant differences in ECI and ECD indexes. The most virulent isolate 8453 (LT 50 = 7.55 days) established in the current study tremendously declined ECI (26.15 %) and ECD (39.84 %) indexes compared to control treatment larvae. However, the least virulent isolate 406 (LT 50 = 10.90 days) could only reduce 7.38 % and 12.06 % of ECI and ECD indexes, respectively. Furthermore, the virulent isolate 8453 established in the current study successful imparted 100 % larval mortality compared with other tested isolates of M. anisopliae. Host antioxidant defense from hemolymph, gut and fat was explored after 24 h of infection by qRT-PCR. The quantification of catalase and peroxidase genes revealed significant differences in their expressions. Overall, the least virulent isolate (406) failed to induce the expression of catalase and peroxidase. However, isolate 8453 greatly induced the expression of studied antioxidant genes. These results indicated that M. anisopliae isolate 8453 seems to be a promising bio-control agent against the infestations of red palm weevils.
