“…Previous studies have reported additive mortality of insect pests with combinations of EPF and various bioinsecticides. Shakarami et al (2015) reported that a mixture of B. bassiana (6.3 × 10 4 conidia ml -1 ) and essential oil of Citrus vulgaris (111 l l -1 ) had a synergistic effect in controlling third instar larvae of E. kuehniella. Similarly, Bahmani et al (2020) found that a mixture of B. bassiana and the microbial insecticide Bacillus thuringiensis kurstaki (BtK), each applied at their LC 50 concentration, resulted in superior control of E. kuehniella larvae compared to separate applications.…”

We evaluated the effi cacy of four entomopathogenic fungi (EPF) and their compatibility with the bioinsecticide spinosad for control of Ephestia kuehniella (Zeller) under laboratory conditions. Three EPF, including Beauveria bassiana (Balsamo-Criveili) Vuillemin isolates Z1 and Iran 1395C, Lecanicillium (= Verticillium) lecanii (Zimmerman) Zare & Gams, isolate Iran 229, and Purpureocillium (Paecilomyces) lilacinum (Thom) Luangs-ard, Hywel-Jones & Samson, isolate Iran 1026 were tested against third and fi fth larval instars of Ephestia kuehniella using a fi lter paper bioassay. Mortality caused by the EPF ranged from 63.3-72.5% for third instars and 50-65.5% for fi fth instars, with LT 50 ranging from 8.4-10.5 d and 10.1-12.9 d, respectively. The effect of spinosad at LC 10 (= 26.2 ppm) on EPF spore germination was evaluated and found to be negligible, ranging from 0% for B. bassiana Z1 to 5.7% for P. lilacinum. The LC 50 values for spinosad against third and fi fth instar E. kuehniella larvae were 452.5 and 1446 ppm, respectively. Subsequently, spinosad at LC 10 was applied to third instar E. kuehniella larvae 24 h before application of the EPFs at LC 50 . The addition of spinosad to applications of L. lecanii and B. bassiana Z1 and Iran1395C isolates synergized their pathogenicity to E. kuehniella larvae, whereas the effect was merely additive for P. lilacinum. Our results suggest that these EPF isolates can be used effectively in combination with spinosad for management of E. kuehniella in stored products.

“…Eucalyptus was thought to act on the nervous system, digestion, growth retardation, and reproductive ability and resulted in mortality of insect which had already penetrated by B. bassiana (Russo et al 2015). The extracts of Citrus vulgaris with B. bassiana also showed synergism ratio of 1.20, representing a viable combination against third instar larvae of Ephestia kuehniella Zeller, where the LC 50 value reduced to 92.32 from 110.98 when B. bassiana alone was used (Shakarami et al 2015).…”

Background Entomopathogens are frequent natural enemies of arthropods worldwide, and they are capable of alternative control agents against the important pests. The optimally selected botanical product can minimize their harmful effect on these entomopathogens, and it becomes essential to know the influence of combinations of botanicals and biopesticides (botanical biopesticide combination (BBC)) in comparison to their sole action. Main body Botanicals, especially neem products, are highly efficient to be combined with the entomopathogens (with some exceptions). There are many possible reasons for the synergistic action of these botanicals, attacking the immune system of the insect being one of the important ones. These botanicals when applied in combination with microbial pesticides showed maximum sublethal effects rather than complete mortality, making them the best alternatives for combating resistance development in insects. To work effectively, biological control agents must be used within a compatible program combined with botanicals. It is highly difficult for such products to compete with chemical controls in high-value crops, so where they can become a commercially viable option in organic cultivation. The increasing acreage is under organic production for high-value export crops, where pesticide residues are undesirable for the environment, and biopesticides and botanicals are good choices for crop protection. Concerning the effect of these products used in pest control, a significant reduction in dosage in relation to the individuals is noticed. Conclusion By combining the performance and safety, biopesticides and botanicals are efficacious. This knowledge should facilitate the choice of biopesticides compatible with less harmful or naturally occurring botanicals. And if these have to be incorporated into a pest management program through an organic approach, it is necessary to determine the effects of botanicals on the beneficial microbes, on the behavior of pest, the importance of application technique, and the role of application timing for these botanical biopesticide combinations.

“…In another study, the fumigant toxicity potential of L. angustifolia oil (LC 50 = 19 µL/L air) was greater than that of R. officinalis oil (LC 50 = 28 µL/L air) as regards E. kuehniella larvae [196]. Essential oils of Artemisia haussknechtii and Citrus vulgaris exhibited LC 50 values of 479.13 and 110.98 µL/L air E. kuehniella [155].…”

Controlling Stored Products’ Pests with Plant Secondary Metabolites: A Review

To date, only a handful of pesticides have been authorized by the European Council for the protection of stored grains. Resistance issues and ecotoxicity concerns necessitate the development of ecofriendly tools in that direction. In this review, we refer to the recent findings on plant extracts and pure plant-derived substances with promising biological activity and the potential to be used as biopesticides for stored products. The main aim of biopesticides is to be effective against target pests, without harming humans and the environment. Many plant species, among those reported herein, are part of the human diet, and are thus not harmful to humans. Edible plant extracts produced with inorganic solvents represent safe candidates for use as repellants, fumigants or contact pesticides. Cinnamon, rosemary, parsley, garlic, oregano and basil are found in products destined for human consumption but also display significant biological activities. Interestingly, cinnamon is one of the most widely tested botanical matrixes, exhibiting the best lethal effects on almost all insect and mite taxa reported herein (Acaroidea, Coleoptera and Lepidoptera), followed by basil and garlic. Prunus persica,Azadirachta indica A. Juss and Carum sp. seem to be very promising too as miticides and/or insecticides, with A. indica already being represented commercially by a plant-derived acaricidal formulation.
