We investigated the occurrence and damage information of 9 species (7 families) of insect pests in two places of rucola (Eruca sativa Mill.) cultivated houses in Gyeonggi Province from 2019 to 2021, and selected five insecticides that could efficiently control the beet armyworm, Spodoptera exigua. Five insecticides (spineram SC, fluxametamide EC, chlorantraniliprole WG, cyantraniliprole DC, and emamectin benzoate EC) showed high control effects over 95% against 3^rd instar larvae of S. exigua at the two places of rucola cultivation, and there was no phytotoxicity at double dose of concentration.

Glucosinolate (GSL) contents were investigated (i) at 1~7 days after sowing (DAS) in seed sprouts and (ii) at 3-7 weeks after sowing for the time-course. Moreover, (iii) They were compared with five different cultivars of rocket salad (Eruca sativa). Seventeen GSLs were separated by HPLC analysis, and 10 GSLs among them were identified as glucoraphanin, sinigrin, glucoalyssin, diglucothiobeinin, glucobrassicanapin, glucoerucin, glucobrassicin, dimeric, 4-mercaptobutyl GSL, 4-methoxy glucobrassicin, gluconasturttin by using LC-APCI-MS analysis, but 7 compounds were not identified. (i) The total GSL content in seed sprouts initially increased up to 3 DAS and then decreased according to their seedling growth. In particular, glucoraphanin known as a strong anti-cancer reagent was found the highest level (5.05 ${\mu}mol/g$ dry wt.) at 3 DAS. The most abundant GSL was glucoerucin ranged from 26.0~49.6 ${\mu}mol/g$ dry wt. (ii) In the time-course, the total GSL contents increased dramatically from 3-week (5.91 ${\mu}mol/g$ dry wt.) to 7-week after sowing (32.2 ${\mu}mol/g$ dry wt.). The major GSLs were glucoraphanin, glucoerucin and 4-methoxy glucobrassicin. (iii) By comparing GSL contents with five different cultivars, the total GSL contents increased from 4-week to 6-week after sowing, regardless of cultivar. In 4-week-old, the order with the total GSL content was "Rucola" > "Rocket Herbs" ${\geqq}$ "Odyssey" > "Takii" > "Herb", but in 6-week-old it is changed as "Takii" > "Herb" > "Odyssey" > "Rucola" > "Rocket Herbs" even there was almost no significantly difference between them.
