Dear Dr Remy Tuey
Thank you for reading the article and the question. This insect has two generations per year at least in Ethiopia. I haven’t seen any article clearly indicating that this insect is a multivoltine. However, some literatures indicated that it survives in wet areas during the off seasons and this report may evidence that this insect has more that one generation.
The pest status of the insect in Ethiopia is increasing. Earlier it was considered as a minor pest of cereal crops but now it is damaging different cereal crops including wheat. However, the pest status depends on locations and the types of available cereal crops. In the rift valley of the country, for example, reports show that there were outbreaks on wheat and wheat was the main cereal crop at the time. In fact, the insect has preference inclined to barley, according to my investigations.
