Selection for resistance to methoxyfenozide and 20-hydroxyecdysone in cells of the beet armyworm,Spodoptera exigua

In this report with an ecdysteroid‐responsive cell line of the beet armyworm, Spodoptera exigua (Se4) selection for resistance against methoxyfenozide and the insect moulting hormone (20‐hydroxyecdysone, 20E) was carried out to analyze the resulting resistant cells in order to elucidate possible mechanisms of resistance towards these compounds. From these cultures, five methoxyfenozide‐ and four 20E‐resistant subclones were selected starting...
