University of Guilan Caspian Journal of Environmental Sciences 1735-3033 20 1 2022 01 01 The toxic impact of the extract of the Dieffenbachia picta leaves on the ratio of death in the termites' workers Microcerotermes diversus (silvestri) [Isoptera: Termitidae] 217 220 5435 10.22124/cjes.2022.5435 EN Sundus Hussein Alwan Department of Biology-College of education - university of Samarra – Iraq Journal Article 2022 02 25 Effects of the extract obtained from the Dieffinbachia picta leaves were examined on the termite workers of Microcerotermes diversus using four treatments (T) including 25%, 50%, 75% and 100% by spraying. The results showed mortality rate in the termite workers at different periods of time. T100% recorded the highest mortality rates (8%, 8.67% and 9%) after 24, 48 and 72 hours respectively, while the minimum mortality in the insect workers was recorded at T25% as 1.7%, 2.3% and 3.7% after 24, 48 and 72 hours respectively. According to results of the present study, there is a possible advantage of the toxic properties of D. picta leaves as an alternative and effective plant pesticides for combating the termite of M. diversus.
