  • METHOD D Diabrotica undecimpunctata (southern corn rootworm) screen Two days before application, seeds of maize were soaked in water under warm conditions to elicit fast germination. One day before application, eggs of Diabrotica undecimpunctata were transferred to one half of a Japanese filter paper placed in a plastic petri dish. Afterwards, a sprouted maize seed was placed on a moistened pad beside the filter paper. Three drops of 200 microlitres of test compound solution were carefully pipetted onto the egg. The remainder of the solution was placed on the maize and then the Petri dish was closed. The treated eggs in the Petri dishes were held in a climate chamber for 6 days. The compound efficacy (percentage of dead eggs and/or larvae in comparison to untreated control) was assessed 6 days after application using a binocular microscope.

After the solution had run off, the rice plants were placed in a Petri dish and populated with about 20 larvae (L3 stage) of the rice leafhopper species Nilaparvata lugens. The Petri dish was closed and then stored in a climatized chamber (16 hours of light/day, 25°C, 40 - 60% relative atmospheric humidity). After 6 days storage, the mortality among the leafhopper larvae was determined.
