“…As Chinese chives and garlic were already tested as an intercrop for the control of N. bilobata, a new pest species in Brazilian strawberry crops [7], this approach may be tested for other pests, such as Drosophila suzukii Matsumura and Duponchelia fovealis Zeller, species with a high potential for causing damage to strawberry. Future studies may also combine sustainable management practices, such as the reduction of the source of fertilization to optimal levels [38,39], use of low impact insecticides and entomopathogenic agents [38,40,41], and incorporation of plants that maintain or enhance natural enemy populations in the crop production landscape [42,43], to build an organic strawberry production protocol that may be used even for conventional strawberry growers or incorporated into others IPM crop protocols.…”

The objective was to evaluate aromatic plants’ effects on the acceptance, preference, egg load, and life span of females of the twospotted spider mite (TSSM) in laboratory experiments and TSSM population under aromatic plants’ intercropping in greenhouse experiments. The pseudofruits production was also evaluated. For the laboratory, basil’s, Chinese chives’, chives’, and garlic’s influence on TSSM were tested on strawberry leaves. Four laboratory experiments were conducted: (1) Multiple choice test; (2) T-shaped arena test; (3) host–plant acceptance on aromatic plant or strawberry leaves; and (4) performance of TSSMs on strawberry leaves under aromatic plant influence. For the greenhouse experiments, assessments of the TSSM populations were realized by observing TSSM with a 10× magnifying glass on strawberry leaves in a monocrop or intercropped with Chinese chives, chives, garlic, or onion. Pseudofruit production was evaluated. Our results show that strawberry leaves were strongly preferred by TSSM. The T-shaped arena test revealed that all aromatic plants repel the TSSM. The test with the performance of TSSM females revealed that aromatic plants affected the mite’s biological parameters. Chinese chives reduced the number of eggs laid per day by 33.22%, whereas garlic reduced the number by 17.30% and chives reduced it by 12.46%. The total number of eggs was reduced by 34.79% with Chinese chives and 25.65% with garlic. Greenhouse experiments showed that chives reduced TSSM populations on two cycles and Chinese chives and garlic reduced TSSM populations on the first cycle only. With our findings, we suggest that Chinese chives, chives, and garlic are the primary candidates for intercropping use against TSSM. Chinese chives and garlic reduced the total number of eggs, but only garlic reduced female mite longevity. However, none of the intercropping plants improved strawberry pseudofruit production.

“…The hallmark finding of this study is that the native isolate BOU1 significantly killed a major insect pest, whitefly. The mortality rate of whitefly induced by this isolate was very high as compared to the previously reported cases in different insects, such as 64% mortality in M. dirhodum [18]; 48% mortality in D. fovealis [19]; and 54% mortality in H. armigera [20] when using different isolates of this entomopathogen. The maximum mortality values caused by C. cladosporioides in T. urticae and T. cinnabarinus are reported to be 81.6…”

“…protease and lipase, play an important role in the pathogenesis and other physiological processes of C. cladosporioides [14,15]; degrade the major constituents of the insect cuticle that allow hyphal penetration into the cuticle [16,17]. The entomopathogenic fungus C. cladosporioides has been reported to infect different species of insects such as aphid, Metopolophium dirhodum (Walker) (Hemiptera: Aphididae) [18]; European pepper moth, Duponchelia fovealis (Zeller 1847) (Lepidoptera: Crambidae) [19]; sweet potato whitefly, Bemisia tabaci Gennadius (Hemiptera: Aleyrodidae) [4]; two-spotted spider mite, Tetranychus urticae Koch (Trombidiformes: Tetranychidae) [5,12]; carmine spider mite, Tetranychus cinnabarinus Boisduval (Trombidiformes: Tetranychidae) [12]; and cotton bollworm, Helicoverpa armigera (H€ ubner 1808) [20].…”

The entomopathogenic fungus Cladosporium cladosporioides is a potential candidate for biocontrol of insect pests. We isolated a strain of C. cladosporioides BOU1 from an infected brown plant hoper (BPH) of rice and characterized it using morpho-physiological and molecular analyses. Internal transcribed spacer regions and intervening 5.8S rRNA gene (ITS) sequencing and morphopathogenic analyses confirmed that BOU1 is a strain of C. cladosporioides. To select the suitable medium for this fungus, a single condium of BOU1 was grown in potato dextrose agar (PDA), potato dextrose agar with yeast (PDAY), Sabouraud dextrose agar (SDA) and synthetic nutrientpoor agar (SNA) media. The suitable medium for this fungal isolate was determined by fungal growth (colony area and conidiogenesis), and enzymatic activities (protease and lipase). The fungal growth parameters including enzymatic activities showed that the PDA medium is most suitable culture medium for C. cladosporioides. Finally, the pathogenicity of this fungal isolate was evaluated against whitefly, Bemisia tabaci through direct contact toxicity assay on eggplant leaves by dipping under laboratory conditions. The BOU1 strain caused mortality in B. tabaci in a dosedependent manner, the highest mortality being 71% at 1 Â 10 8 conidia/mL. To the best of our knowledge, this is the first report of isolation and molecular characterization of an entomopathogenic fungus C. cladosporioides from a BPH of rice. This study suggests that BOU1 is a potential candidate for biological control of whitefly for the promotion of sustainable agriculture.

“…At high concentration on older pupae, developed adults died inside puparia. As mentioned by Amatuzzia et al, (2018) F. solani induced low mortality (32%) when applied as a biocontrol agent of Duponchelia fovealis (Zeller) (Lepidoptera:Crambidae) Many studies were conducted on the safety of using insect-pathogenic fusaria on plants showed different results. A study was performed to test the infectious effect of F. oxysporum isolated from the brown planthopper, Nilaparvata lugens Stål (Hemiptera: Delphacidae) on the rice, cotton and tomato plants.…”

The journal of Toxicology and pest control is one of the series issued twice by the Egyptian Academic Journal of Biological Sciences, and is devoted to publication of original papers related to the interaction between insects and their environment. The goal of the journal is to advance the scientific understanding of mechanisms of toxicity. Emphasis will be placed on toxic effects observed at relevant exposures, which have direct impact on safety evaluation and risk assessment. The journal therefore welcomes papers on biology ranging from molecular and cell biology, biochemistry and physiology to ecology and environment, also systematics, microbiology, toxicology, hydrobiology, radiobiology and biotechnology. www.eajbs.eg.net Provided for non-commercial research and education use.Not for reproduction, distribution or commercial use. ABSTRACT Article HistoryA total of 26 fungal strains were isolated from aphids and tomato leaf miner as indigenous species and from red palm weevil and peach fruit fly as an invasive insect. Fungal strains tested for their abilities to attack both bean and wheat aphids. The mortality of aphids due to these fungi was estimated. Results showed that eight entomopathogenic fungi Scopulariopsis brevicaulis, Verticillium sp., Fusarium chlamydosporum, Fusarium proliferatum, Fusarium semitectum, Pochonia chlamydosporia var. catenulata, Fusarium solani and Fusarium verticillioides exhibited high virulence 60-100%. However, Scopulariopsis brevicaulis, Verticillium sp., Fusarium chlamydosporum and Fusarium solani proved to be the most virulent species against the target aphids inducing 90%-100% mortality.
