“…Tetranychus cinnabarinus Boisduval (spider mite), Mythimna separata Walker (Oriental armyworm), and Plutella xylostella Linnaeus (diamondback moth) are three serious and typical agriculture-threatening pests, and their outbreaks can result in a significant loss of crops. − For instance, due to the intermittent outbreaks of third-generation larvae of M. separata occurring in 2012, nearly 4 million hectares of crops in China were entirely lost . However, because of extensive and unreasonable application of synthetic agrochemicals to deal with pests outbreaks, currently, resistances in pest populations and negative impacts on human health and environment have been simultaneously developed. − Therefore, discovery of the potential alternatives to efficiently control pests for crop protection is highly urgent. Natural products could play an important role for affording lead compounds in the discovery of pesticide candidates. − …”

In continuation of our program to discover new potential pesticidal agents, thirty-one piperine analogs containing isoxazoline/pyrazoline scaffold were prepared, and confirmed by infrared spectra, proton/carbon-13 nuclear magnetic resonance spectra, and high-resolution mass spectra. The structures of compounds VIIb and VIIIc were further determined by 1 H− 1 H COSY spectra. Especially the configuration of compound VIIIc was unambiguously confirmed by singlecrystal X-ray diffraction. Their pesticidal activities were evaluated against three serious and typically crop-threatening agricultural pests, Tetranychus cinnabarinus Boisduval (spider mite), Mythimna separata Walker (Oriental armyworm), and Plutella xylostella Linnaeus (diamondback moth). Compounds VIIIb and VIIIc exhibited greater than 40-fold more potent acaricidal activity than the lead compound piperine against T. cinnabarinus. Notably, compounds VIa−c exhibited more pronounced oral toxicity against P. xylostella than toosendanin; compounds VIb and VIc displayed more promising growth inhibitory activity against M. separata than toosendanin. It demonstrated that the methylenedioxy and isoxazoline scaffolds were important for the oral toxicity and growth inhibitory activity against P. xylostella and M. separata, respectively; the ethylenedioxy and isoxazoline scaffolds were vital for the acaricidal activity against T. cinnabarinus. Moreover, compounds VIb, VIIf, and VIIIc showed very low toxicity against NRK-52E cells.

“…The fungus develops white color in Petri plate culture and produces specific dry and powdery conidia in the culture medium. B. bassiana can be used as a biological insecticide to control thrips, mites, whiteflies and many other arthropod pests (Erler et al, 2013(Erler et al, , 2014Erler & Ates, 2015;Topuz et al, 2016). After the spores stick onto the insect cuticle, they extend their hyphae into the insect's body and begin to multiply.…”

The western flower thrips, Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae), one of the main pests of agricultural areas, causing occurrence of significant economic losses if no control measure is taken. In recent years, the use of entomopathogenic fungi (EPF), an alternative method of control, has come into the prominence. EPF have a different place among insect pathogens in terms of direct infection of hosts through the integument. The most common fungal pathogens of F. occidentalis are Verticillium lecanii, Beauveria bassiana, Entomophtholares spp. and Metarhizium anisopliae. In Turkey, only V. lecanii and B. bassiana are commercially licensed against F. occidentalis. In this review, the usage possibilities of these two fungi, as well as the use of other species in controlling the pest will be discussed.

“…Entomopathogenic fungal inocula targeting the control of soil insects have been formulated as colonized grains, such as barley, millet, rice and maize [ 13 , 25 , 26 ]. These grains nutritionally support the growth of EPF propagules in soil, providing crop protection against soil insects [ 27 , 28 ]. The presence of insect and plant hosts in the soil can further improve the EPF growth and persistence in soil, but the saprophytic growth of EPF is important to maintain propagules at high enough levels to result in insect infection and rhizosphere colonization [ 29 ].…”

Resporulation of Calcium Alginate Encapsulated Metarhizium anisopliae on Metham®-Fumigated Soil and Infectivity on Larvae of Tenebrio molitor

Metarhizium anisopliae infects and kills a large range of insects and is a promising biocontrol agent to manage soil insects, such as wireworm in sweetpotato. The presence of other soil microbes, which exhibit competitive fungistasis, may inhibit the establishment of M. anisopliae in soil. Microbially depleted soil, for example, sterilized soil, has been shown to improve the resporulation of the fungus from nutrient-fortified M. anisopliae. Prior to planting, sweetpotato plant beds can be disinfected with fumigants, such as Metham®, to control soil-borne pests and weeds. Metham® is a broad-spectrum soil microbial suppressant; however, its effect on Metarhizium spp. is unclear. In the research presented here, fungal resporulation was examined in Metham®-fumigated soil and the infectivity of the resulting granule sporulation was evaluated on mealworm, as a proxy for wireworm. The fungal granules grown on different soil treatments (fumigated, field and pasteurized soil) resporulated profusely (for example, 4.14 × 107 (±2.17 × 106) conidia per granule on fumigated soil), but the resporulation was not significantly different among the three soil treatments. However, the conidial germination of the resporulated granules on fumigated soil was >80%, which was significantly higher than those on pasteurized soil or field soil. The resporulated fungal granules were highly infective, causing 100% insect mortality 9 days after the inoculation, regardless of soil treatments. The results from this research show that the fungal granules applied to soils could be an infective inoculant in sweetpotato fields in conjunction with soil fumigation. Additional field studies are required to validate these results and to demonstrate integration with current farming practices.
