“…This resistance has been frequently attributed to the use of insecticides at high doses (Barathi et al, 2024;Helps et al, 2020). In addition, this resistance can be caused by the limited rotation of the modes of action of the insecticides (Madgwick & Kanitz, 2024;Sparks et al, 2021).…”

Rhyzopertha dominica (F.) is a major pest in stored cereals in Colombia, which causes significant lossesin production. Chemical control is the main tool used in the country, and despite the common use ofinsecticides such as deltamethrin, resistance has been observed in some Colombian populations but isa worldwide problem. The objective of this work was to evaluate the efficacy of deltamethrin and thecombination of deltamethrin and piperonyl butoxide in Colombian populations of R. dominica. Failureto control and survival tests showed that the recommended doses on product labels were insufficient toprotect the grain from this pest. Failure control demonstrated that mortality did not exceed 80 percent inthe populations studied. Differences in susceptibility were observed between populations, with El Espinaland Neiva highlighted as less susceptible and Pore as the most sensitive to the action of insecticides.The combination of deltamethrin and piperonyl butoxide reduced insect survival but did not effectivelycontrol it (0–20%). These results suggest that R. dominica may be developing resistance to insecticides,as has been found in other countries. This underscores the importance of conducting toxicological studies and the need to investigate molecules with diverse modes of action, contributing to the strengthening ofchemical management strategies. To achieve effective control, it is necessary to implement IntegratedPest Management (IPM) with a focus on alternative methods to chemical control.

“…Numerous studies researching and using insecticides with high virulence against ALB at different stages have been conducted [1,6,7]. However, excessive and consecutive use of chemical insecticides can have a harmful effect on the environment and cause resistance of pests to pesticides, which is why alternatives to chemical insecticides are needed [8]. As almost no reports on the resistance caused by entomopathogenic fungi can be found, they are a good candidate for insect control.…”

The Asian long-horn beetle (ALB) is a serious wood-boring insect. Continuous isolation of different fungal strains is vital for using fungi for the control of ALB. The virulence and pathological characteristics of a new Metarhizium anisopliae strain DES3 isolated from the desert afforestation stands against the larvae of ALB were assessed in this study. The corrected mortality reached 100% at the conidial concentration of 109 and 108 conidia/mL, and 91.11 ± 4.44% at 107 conidia/mL. Similarly, the LC/LT showed high virulence as well. Meanwhile, the virulence of a commercial M. anisopliae strain against the ALB larvae was evaluated. The corrected mortality was only 33.33% at 109 conidia/mL, and less than 10% at 108 conidia/mL. The pathological characteristics after infection by the M. anisopliae strain DES3 were evident, mainly embodied in the rupture of the adipose tissue, muscle tissue, and midgut. But there was no obvious change after infection by the commercial M. anisopliae strain. In conclusion, these results establish that the M. anisopliae strain DES3 has high virulence in a dosage-dependent manner against ALB larvae, indicating the potential of fungal strain DES3 to be developed as biopesticide for biocontrol of A. glabripennis.

Viral diseases like yellow fever, dengue, and Zika have an alarming impact on public health. These diseases can be transmitted by Aedes mosquito species, such as Ae. albopictus, which is now found in many countries outside its original range. Xenorhabdus and Photorhabdus spp. are enteric bacterial symbionts of insect-preying nematodes and are known to produce an array of natural products with various activities including larvicidal activity. In this study, the effects of natural products produced by four Xenorhabdus and one Photorhabdus bacteria on the ovipositional behavior of Ae. albopictus mosquitoes were assessed. Utilizing a binary choice assay in insect cages, gravid female mosquitoes were presented with two oviposition cups containing water supplemented with varying concentrations of bacterial supernatants (50–1% concentrations) versus control medium. After 72 h, the eggs deposited on filter papers were counted. The oviposition attractant index (OAI) feature of the bacterial supernatant was evaluated using the number of eggs laid in the cups. Notably, all tested supernatants exhibited concentration-dependent deterrence of oviposition. Xenorhabdus cabanillasii displayed the strongest deterrent effect, inhibiting egg-laying at 50–5% concentrations (OAI: − 0.87 to − 0.35), followed by X. nematophila (50–10%, OAI: − 0.82 to − 0.52). Xenorhabdus szentirmaii, X. doucetiae, and P. kayaii showed significant deterrence at ≥ 20% concentrations. Using promoter exchange mutants generated by the easyPACId approach, fabclavine from X. szentirmaii was identified as the bioactive compound with evident deterrent effects. Such deterrents targeting egg-laying could be valuable for controlling populations by disrupting their breeding in suitable habitats.
