“…There are many ways on how to control the pest without the use of synthetic insecticides, which underlines the desirability of further efforts to develop new technologies to control WCR. They include the use of entomopathogenic nematodes (Toth et al, 2020, Modic et al, 2020, entomopathogenic fungi (Mulock and Chandler, 2001), RNAi-based insecticides (Ražná and Cagáň, 2019), etc.…”

The aim of the study was to find the level of repellent effect of two chemical substances (DEET and 2-Undecanone) and two essential oils (from Allium sativum and Eucalyptus oil) on the Western corn rootworm (WCR), Diabrotica virgifera virgifera LeConte, 1868 in field conditions. Repellents were used in the area of 5 x 4 meters with four replications. They were applied as a solution of 700 μl chemical/essential oil in one litter of water. TWEEN 80 was used as a surfactant.After 24 and 48 hours, the repellent effect was checked by visual observation. After 24 hours, yellow sticky traps were installed in each plot and checked after the next 24 hours for the detection of the WCR adult beetles. The experiment was carried out during two years (2019 and 2020) in a maize field in Mojmírovce (48.199284°N, 18.038637°E), Slovakia.The results showed significant repellent effect of chemicals DEET and 2-Undecanone on WCR adults. After 48 hours the number of beetles per plant was significantly higher compared to the control for both DEET and 2-Undecamone. This was confirmed by yellow sticky traps in 2020, but not in 2019, probably due to the lower catching of WCR adults. The results indicate that repellent substances can influence the number of the WCR adults in maize fields.

MicroRNAs (miRNAs) have started to play an important role in pest control, and novel miRNA‐based transgenic insect‐resistant plants are now emerging. However, an environmental risk assessment of these novel transgenic plants expressing insect miRNAs must be undertaken before promoting their application. Here, transgenic miR‐14 rice, which has high resistance to the rice stem borer Chilo suppressalis, was used as an example for evaluation in this study. Taking the tier 1 risk assessment method in Bacillus thuringiensis (Bt) crops as a reference, the effects of the direct exposure of a non‐target parasitoid, Cotesia chilonis, to a high concentration of miRNA were evaluated. The results showed that direct feeding with miR‐14 at high concentration had no significant effects on the biological parameters of Co. chilonis, whereas when miR‐14 was injected into Ch. suppressalis‐parasitized larvae, the development duration of Co. chilonis was significantly affected. In combination with the real conditions of the rice paddy field, it could be inferred that transgenic miR‐14 rice has no significant negative effects on the important non‐target parasitoid, Co. chilonis. These results will provide a foundation for the establishment of a new safety evaluation system for novel RNAi‐based transgenic plants.
