“…Through data analysis of life table parameters, the r , λ , R 0 and T of the F 1 generation changed significantly, and the r , λ and R 0 of the LC 25 treatment group were significantly shorter than those of the control group. Similarly, the r , λ and R 0 were shorter than the control but T was not changed significantly after Bactericera cockerelli (Sulc) (Hemiptera: Triozidae) were treated with sub-lethal doses of B. bassiana [ 47 ]. Our results showed that the T of the LC 25 treatment was significantly longer than that of the control; similarly, B. bassiana had this effect on Helicoverpa armigera (Hübner) (Lepidoptera: Noctuidae) and Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae) [ 48 , 49 ].…”

Rice (Oryza sativa) is the most important food crop all over the world, while white-backed planthopper (WBPH), Sogatella furcifera (Horváth) (Hemiptera: Delphacidae) is an important pest causing rice yield reduction. The purpose of this study is to evaluate the sublethal effects of strain BEdy1 Beauveria bassiana (Bals.-Criv.) Vuill. (Hypocreales: Cordycipitaceae) on S. furcifera using the two-sex life table analytical method, compare the life tables of the F0 and F1 generations of WBPHs which were treated with sublethal concentrations (LC10, LC25) of B. bassiana BEdy1 with a control group. The results showed that the duration of the egg, 4th-instar and 5th-instar nymph, pre-adult, total pre-oviposition (TPOP) and mean generation time (T) for the LC25 treatment were significantly longer than those of the control and LC10 treatment. However, the duration of the adult, the longevity of male and female adults and the oviposition days of female adults for the LC25 treatment were significantly shortened. The fecundity of female adults, intrinsic rate of increase (r), net reproductive rate (R0) and finite rate of increase (λ) for the LC25 treatment were significantly decreased compared with those of other treatments. The duration of the egg and pre-adult stage for the LC10 treatment were longer than those of the control group, but the population parameters showed no significant difference. Therefore, the LC25 of B. bassiana BEdy1 can inhibit the population growth of S. furcifera.

“…Similarly, entomopathogenic fungus, Beauveria bassiana, was able to significantly increase the mortality rate of both nymphs and adult forms of tomato/potato psyllid. If not controlled, this tomato/potato psyllid affects bell pepper, eggplant, potato, and tomato, while secondary metabolites such as oosporeins, bassiacridin, and bassianin were responsible for the high mortality rate [131,132]. In the same vein, methanol extracts from Cladosporium cladosporioides and Purpureocillium lilacinum have been used to effectively control the population growth of Aphis gossypii and cotton aphid.…”

The increase in demand for agricultural produce necessitates the continuous search for affordable, ecofriendly, readily available crop protectors, and food preservatives. Historically, the use of various chemicals was employed in controlling plant diseases and to maintain food quality. In the past few decades, several natural product-based alternatives have been discovered and projected as better alternatives to synthetic pesticides and other synthetic agrochemicals. Recent studies focusing on the application of different botanicals in crop protection and food preservation were carefully selected and reviewed. The application of plant extract in the biogenic preparation of nanoparticles was also reviewed. This review confirms that several natural products can be used as a safe replacement for synthetic agrochemicals. Different plant extracts have also served as feed for the synthesis of nanoparticle, which is increasingly applicable in crop protection and food preservation.

“…Demographic toxicology has been suggested as the best way to evaluate total effects (lethal and sub-lethal) of entomopathogens, because it is based on both survivorship and fecundity parameters (Stark and Banks, 2003; Sedaratian et al ., 2013, 2014; Liu et al ., 2019). Considering the potential effects of sub-lethal exposure to EPF ( B. bassiana ) on pest populations, this study's objective is to improve the management of T. urticae .…”

Tetranychus urticae (Acari: Tetranychidae) is one of the most important pests of agricultural crops with worldwide distribution causing considerable damage to different products. Application of chemical acaricides is one of the most important strategies used for the control of this pest. Entomopathogenic fungi, however, have been proposed as alternative control agents. In this study, sub-lethal effects (LC10 = 6.76 × 102, LC20 = 8.74 × 103, and LC30 = 55.38 × 103 conidia ml−1) of Beauveria bassiana strain TV on the life table parameters of T. urticae were evaluated under laboratory conditions. The results demonstrated that by increasing the concentration, a significant decline was observed in adult longevity of both male and female individuals. Total fecundity of T. urticae was calculated as 45.16, 36.28, 23.98, and 18.21 eggs in control, LC10, LC20, and LC30 treatments, respectively. Sub-lethal concentrations drastically affected the population parameters of this mite pest. The intrinsic rate of increase (r) ranged from 0.1983 to 0.1688 day−1 for the mites treated with distilled water and LC20 treatments, respectively. The net reproductive rate (R0) was affected by the sub-lethal concentrations (lower value at LC30 concentration: 11.19 offspring/individual). Considering the detrimental effects of B. bassiana on some biological parameters of T. urticae, it can be concluded that this product can be used to develop targeted interventions aimed at integrated pest management of this pest.
