Laboratory spraying experiments were carried out with DDT, allethrin, the triethanolamine salt of 3:5 dinitrocresol (TDNOC) and HETP against eggs of different ages of Diataraxia oleracea (Lepidoptera) and with allethrin, HETP and TDNOC against eggs of different ages of Ephestia kühniella (Lepidoptera) and Dysdercus fasciatus (Hemiptera) under controlled temperature and humidity conditions.
