“…In the present study, the isolates of B. bassiana caused 87.3% egg mortality in FAW. Our results are supported by those of previous studies, wherein different isolates of B. bassiana were found to be able to induce the egg mortality of S. frugiperda [ 61 , 62 , 78 ], Spodoptera exigua [ 79 ], Maruca vitrata [ 80 ], Perileucoptera coffeella [ 81 ] and Phthorimaea operculella [ 82 ].…”

The control of Spodoptera frugiperda, the key invasive pest of maize, is a serious concern due to its biology and the current global restriction on applying synthetic pesticides. Entomopathogenic fungi are considered to be a potential biological control strategy. The pathogenicity of 12 isolates of Beauveria bassiana in the immature stages and feeding efficacy of S. frugiperda were evaluated. The B. bassiana isolates QB-3.45, QB-3.46 and QB-3.428 caused the highest egg mortality rates of 87.3, 82.7 and 79.3%, respectively, when applied at a concentration of 1 × 108 conidia/mL and measured at 7 days post-treatment. Neonate mortality rates of 45.6 to 53.6% were observed with the same isolates. The B. bassiana isolates caused significant cumulative mortality rates ranging from 71.3 to 93.3% at 14 days post-treatment and reduced larval feeding efficacy from 69.4 to 77.8% at 48 h post-treatment. This study supports using the effective B. bassiana isolates as a biological control agent against S. frugiperda. The significant mortality of the eggs and neonatal larvae and the reduction in the feeding efficacy of the second instar larvae of the S. frugiperda that were treated with isolates of B. bassiana supports the application of entomopathogenic fungi as a biocontrol agent for the effective control of the S. frugiperda population.

“…Al‐Kherb () also reported ovicidal activity of both M. anisopliae and B. bassiana isolates to beet armyworm, Spodoptera exigua (Hübner) (Lepidoptera: Noctuidae), causing 37% and 50% egg mortality, respectively. Ovicidal activity of M. ansiopliae and B. bassiana has been previously reported on other lepidopteran insects such as Maruca vitrata (Fabricius) (Lepidoptera: Crambidae) (89%–100% mortality) (Ekesi, Adamu, & Maniania, ), coffee leafminer, Perileucoptera coffeella (Guérin‐Meneville) (Lepidoptera: Lyonetiidae) (27.4%–96.9% mortality) (Villacorta, ) and Potato tuber moth, Phthorimaea operculella Zeller (63% mortality) (Khorrami, Mehrkhou, Mahmoudian, & Ghosta, ).…”

Maize is a major staple food for over 300 million people in sub-Saharan Africa.Sustainable productivity of this primary crop has been recently threatened by Fall armyworm (FAW), Spodoptera frugiperda invasion. Due to lack of environmentally safe management strategies, immediate responses by growers and governments to tackle FAW are based on rampant use of pesticides. Looking for efficient biopesticides, twenty entomopathogenic fungal isolates (14 Metarhizium anisopliae and 6Beauveria bassiana) were screened for their efficacy against eggs and second instar larvae of FAW. A single discriminating concentration of 1 × 10 8 conidia ml −1 and four replicates per treatment were used in all experiments. Isolates were assessed for their ability to cause mortality of FAW second instar larvae, eggs and the neonate larvae that emerged from treated eggs. Among the isolates tested, only B. bassiana ICIPE 676 caused moderate mortality of 30% to second instar larvae. Metarhizium anisopliae ICIPE 78, ICIPE 40 and ICIPE 20 caused egg mortalities of 87.0%, 83.0% and 79.5%, respectively, and M. anisopliae ICIPE 41 and ICIPE 7 outperformed all the others by causing 96.5% and 93.7% mortality to the neonate larvae, respectively. The cumulated mortality of eggs and neonates was highest with M. anisopliae ICIPE 41 (97.5%), followed by M. anisopliae ICIPE 7, 655, 40, 20 and 78 with total mortality of 96.0%, 95.0%, 93.5%, 93.0% and 92.0%, respectively. These isolates with high cumulated mortality (≥92%), especially ICIPE 78 and 7, which are already commercialized for spider mites and ticks control respectively, would be good candidates for development as biopesticides for management of FAW in Africa if further evidence of their efficacy is obtained in the field.

“…The potato ( Solanum tuberosum L.) is an economically important and widely cultivated member of the Solanaceae family. Approximately five million tons are harvested from 150 000 ha, and it is the fourth largest crop in Iran after wheat, maize, and rice 1–3 . The Colorado potato beetle (CPB), Leptinotarsa decemlineata (Say), is one of the most harmful aboveground pests in potatoes and other solanaceous crops' agroecosystems 4 .…”

BACKGROUND: The use of pest-resistant or less susceptible plant varieties is of great importance for integrated pest management programs. This study was conducted to evaluate the resistance of seven potato cultivars to a major pest, namely the Colorado potato beetle (CPB), by measuring its bio-physiological aspects. RESULTS:The longest developmental time and the lowest survival rate of CPB were detected on cultivar 'Manitou.' Although the larvae fed voraciously, the food conversion efficiency was the lowest on this cultivar leading to the lowest relative growth rate. Furthermore, larvae reared on Manitou had the lowest total protease activity and specific activity values of cathepsin B compared to the larvae reared on other cultivars. Additionally, the cluster analysis showed that the Manitou cultivar was the least suitable (partially resistant) CPB. Moreover, the results indicated that the protein content was the lowest in the Manitou cultivar; conversely, this cultivar was rich in polyphenol and flavonoid compared to Agria and Santae cultivars. CONCLUSION:The overall results in this study indicated that the Manitou cultivar might be a good candidate to be incorporated into integrated pest management programs.
