Dociostaurus maroccanus Thunb. is polyphagous and highly adaptable locust. In severe infestations, it
may devastate tobacco fields completely.
During 2016/2017 its quantitative representation was studied. A sweep net method was used around the
tobacco plots, at 10-day intervals, during June and July. The method of survey was applied on 100 randomly
selected tobacco plants, at 10-day intervals, during July, August and September. Five insecticides were applied
for its control, with active ingredients Deltamethrin, Esfenvalerate, Lambda-cyhalothrin,
Chlorpyrifos+cypermethrin and Chlorpirifos.
The species is present on tobacco from July until the end of September in “solitary phase”. The locusts
damage tobacco leaves and make irregular holes. In 2016 and 2017, the Moroccan locust was found in increased
number (805 and 724, respectively), compared to its usual occurrence.
Chemical protection must be based on treatments given in due time and on restriction of treatment to
the smallest possible area. The applied insecticides provide a high level of control.
