“…Due to the widespread nature of pepper cultivation in Korea, pests, including insects, fungi, and weeds, continue to be a serious threat to high-quality agricultural yields 33 – 36 . In the Republic of Korea, anthracnose and oriental tobacco budworm are recurring problems in pepper cultivation, and fungicides and insecticides are used annually to control them 37 . Chlorothalonil is a registered fungicide for controlling anthracnose, and flubendiamide is a registered insecticide for controlling oriental tobacco budworm in peppers 10 , 34 , 38 .…”

Pesticides are indispensable tools in modern agriculture for enhancing crop productivity. However, the inherent toxicity of pesticides raises significant concerns regarding human exposure, particularly among agricultural workers. This study investigated the exposure and associated risks of two commonly used pesticides in open-field pepper cultivation, namely, chlorothalonil and flubendiamide, in the Republic of Korea. We used a comprehensive approach, encompassing dermal and inhalation exposure measurements in agricultural workers during two critical scenarios: mixing/loading and application. Results revealed that during mixing/loading, dermal exposure to chlorothalonil was 3.33 mg (0.0002% of the total active ingredient [a.i.]), while flubendiamide exposure amounted to 0.173 mg (0.0001% of the a.i.). Conversely, dermal exposure increased significantly during application to 648 mg (chlorothalonil) and 93.1 mg (flubendiamide), representing 0.037% and 0.065% of the total a.i., respectively. Inhalation exposure was also evident, with chlorothalonil and flubendiamide exposure levels varying across scenarios. Notably, the risk assessment using the Risk Index (RI) indicated acceptable risk of exposure during mixing/loading but raised concerns during application, where all RIs exceeded 1, signifying potential risk. We suggest implementing additional personal protective equipment (PPE) during pesticide application, such as gowns and lower-body PPE, to mitigate these risks.

“…A laboratory colony of F. occidentalis was obtained as a donation from the National Academy of Agricultural Sciences (Jeonju, Korea), and this was confirmed to be classified into G strain of the thrips 3 . Its rearing proceeded according to the method described in a previous study 3 . Our standard conditions in the rearing room are 25 ± 2 °C, 16L:8D photoperiod and 65 ± 5% relative humidity.…”

“…It inflicts feeding and ovipositing damages to crops and can indirectly transmit a plant disease virus called tomato spotted wilt virus (TSWV) 2 . To control thrips, different chemical insecticides have been applied to various crops, including hot peppers in Korea 3 . However, several outbreaks of F. occidentalis occur every year, and these seriously affect the crop yields 4 .…”

The western flower thrips, Frankliniella occidentalis, is an insect pest, and its aggregation pheromone (AP) plays a crucial role in the recruitment of both sexes. A novel pheromone biosynthesis-activating neuropeptide (PBAN)-like gene is encoded in F. occidentalis genome, but its physiological function has yet to be elucidated. This study hypothesized the physiological role played by PBAN in mediating AP production. AP has been known to be produced only by male adults in F. occidentalis. Surprisingly, our extraction of headspace volatiles contained two AP components in females as well as in males with similar composition. PBAN injection elevated the AP production whereas RNA interference (RNAi) of the gene expression suppressed the AP production in both sexes. A biosynthetic pathway to produce AP components were predicted and the enzymes catalyzing the main steps were confirmed in their expressions. Individual RNAi treatments of these genes significantly suppressed AP production. RNAi of PBAN gene downregulated the expressions of these biosynthesis-associated genes in both sexes. These results suggest that the novel neuropeptide acts as PBAN mediating AP production through stimulating its biosynthetic machinery in F. occidentalis.

Pesticides are indispensable tools in modern agriculture for enhancing crop productivity. However, the inherent toxicity of pesticides raises significant concerns regarding human exposure, particularly among agricultural workers. This study investigated the exposure and associated risks of two commonly used pesticides in open-field pepper cultivation, i.e., chlorothalonil and flubendiamide, in the Republic of Korea. We used a comprehensive approach, encompassing dermal and inhalation exposure measurements in agricultural workers during two critical scenarios: mixing/loading and application. Results revealed that during mixing/loading, dermal exposure to chlorothalonil was 3.33 mg (0.0002% of the total active ingredient [a.i.]), while flubendiamide exposure amounted to 0.141 mg (0.0001% of the a.i.). Conversely, dermal exposure increased significantly during application to 648.96 mg (chlorothalonil) and 930.97 mg (flubendiamide), representing 0.037% and 0.066% of the total a.i., respectively. Inhalation exposure was also evident, with chlorothalonil and flubendiamide exposure levels varying across scenarios. Notably, the risk assessment using the Risk Index (RI) indicated safe exposure levels during mixing/loading but raised concerns during application, where all RIs exceeded 1, signifying potential risk. We suggest implementing additional personal protective equipment (PPE) during pesticide application, such as gowns and lower-body PPE, to mitigate these risks.
