Lethal effects of allyl isothiocyanate on the egg masses of flighted spongy moth complex Lymantria dispar japonica (Lepidoptera: Erebidae). [PDF]

Pest Manag Sci
This study showed that AITC substance was lethal effect to Lymantria dispar japonica egg mass, and our results show a significant decline in egg hatching rate with increasing AITC concentrations. Abstract BACKGROUND The flighted spongy moth complex (FSMC) lays egg masses not only on host plants but also various artificial structures, such as, cargo ...
