“…Although there was a steady increase in larval mortality in 6 days, the data showed a significant difference between the B. bassiana and M anisopliae isolates unlike that of their effect on the adult aphids (Table 4 and Table 5). The mortality of the aphids recorded in this study was much better than the 39% and 80 % mortality recorded with a bio-control agent B. bassiana CKB-048 at a concentration of 2 ×10 8 after 3 and 7 days of treatment, respectively (Maketon et al, 2013).…”

Cabbage aphid (Brevicoryne brassicae L.) is an important sucking insect pest of cabbage and other vegetables. It can be controlled using continuous chemical insecticides that cause human health and environmental problems. The present study was, therefore, designed to evaluate antagonistic activities of indigenous entomopathogenic fungi together with selective insecticides within the context of integrated pest management (ipm). To this effect, four strains of entomopathogenic fungi from Beauveria bassiana and Metarhizium anisopliae were tested for their antagonistic activities against the cabbage aphid. The result showed that microbial inoculums of 1×107 and 1×108 conidia mL-1 showed high mortality (66.7-100%) of aphids after 6 days of incubation under laboratory condition. Among them, bei1 (B. bassiana) isolate was the most virulent strain on adult aphids and nymphs showing 67 to 100% and 39-72% mortality after 4th-5th days of treatments. The data also indicated that the fungal isolates were compatible to the three insecticides with 70% - 91% conidial germination by M. anisopliae and 68%-98% conidial germination by B. bassiana after 24 hours of treatment of which Karate was the most compatible insecticide to the isolates. The single treatment with the entomopathogens gave a substantial percentage mortality of insect pests after 11 days compared to (80-100%) mortality obtained from a combined treatment with half recommended dose of Karate in seven days, which was similar to the treatment with full dose of the insecticide control. The treatments were slightly more effective on adults than they were on aphid larvae. It is interesting to note that the combination of bei1 + Ka induced 100% mortality of adult aphids after seven days of incubation compared to the 11 day incubation required to kill the nymphs. Given that the full dose of karate killed the adult aphids in five days, the 100% mortality of the half dose of karate with bei1 within seven days was a good indication that the ipm could reduce pollution problem. Thus, B. bassiana and M. anisopliae with Karate could be further tested in the field to realize their potential as bioinsecticides for integrated pest management to control mustard aphids.

“…At the highest concentration of 10 8 spores/ ml, the LT50 values for B. bassiana, H. thompsonii, V. lecanii, C. oxysporum and M. anisopliae were 3.63, 3.64, 3.90, 5.24 and 5.54 days, respectively. Also, Maketon et al (2013) studied the use of B. bassiana CKB-048 against the cowpea aphid (A. craccivora). LC50 was 6.69 × 10 7 conidia/ml for the nymphs and 8.25 × 10 7 conidia/ml for the adults.…”

Four native isolates of entomopathogenic fungi (EPF) Beauveria bassiana (B1and B2), Metarhizium anisopliae (M1 and M2 ) were isolated and evaluated against wheat aphid, Schizaphis graminum (Rondani). Three concentrations of spores suspension from each of the four fungal isolates (1×10 6 , 1×10 7 and 1×10 8 conidia) were used against adult aphid (one day old). The results showed that (B1) was the most effective according to LC50. Whereas, when testing the toxicity of crude metabolites of fungal isolates in four concentrations for each isolate, it was found that the highest effective toxin was (M1) followed by (B1), (M2) and (B2). Scanning electron microscope photographs (SEM) showed the mode of action of entomopathogenic fungi and its ability to colonize and how it infects aphid.

“…This research highlights the potential of M. anisopliae as a promising biocontrol agent for Monocesta coryli. In the same line, Maketon et al (2013) examined the efficacy of B. bassiana against A. craccivora. The results indicated that the LC50 was 6.69 × 10 7 spores/ml for the nymphs and 8.25 × 10 7 spores/ml for the adults.…”

Entomopathogenic fungi and aphid predators can independently manage Aphis craccivora, Koch (Hemiptera: Aphididae) populations. It is important to assess the risk of possible fungal infections in predators when integrated in Integrated Pest Management (IPM). The virulence of two entomopathogenic fungi isolates, Beauveria bassiana (Balsamo) and Paecilomyces lilacinus (Thom) Samson have been tested against A. craccivora. A laboratory experiment was conducted to study the direct spray effect of different spores' concentrations on the aphid adult stage. The obtained results indicated that B. bassianais was more efficient against A. craccivora according to LC50,1.2×10 7 spores/ml. LC50 of B. bassiana isolate was applied against the second larval instars of both the green lacewing, Chrysoperla carnea (Stephens) (Neuroptera: Chrysopidae) and the seven spotted lady beetles, Coccinella septempunctata (Linnaeus) (Coleoptera: Coccinellidae). The bioassay indicated that B. bassiana was slightly harmful against Ch. carnea and significantly injurious against C. septempunctata. The total mortality was 13.3 and 43.3% for Ch. carnea and C. septempunctata, respectively. According to the high pathogenic efficiency of B. bassiana on aphids and the low efficiency on the Ch. carnea, the finding suggested that B. bassiana has the potential to be utilized as highly efficient entomopathogenic fungi in IPM programs, in conjunction with the predator Ch. carnea, against A. craccivora.
