【Abstract】 Effectiveness of diatomite and its mixtures with pesticides against the booklice Liposcelis bostrychophila in wheat was tested. Under the condition of RH 75%～85%, (28±2)℃, the mixture of diatomite and enidiadin EC (0.4%) was the best , for 100% of the booklice were killed 24 h later in three tested concentrations. The 100% mortality of the booklice were also reached 48 h later in treatments of other diatomite mixtures, with fenoxycard WP(5%), malathion EC (95%), deltamethrin EC (2.5%), dichlorvos EC (80%), or chlorfluazuron EC (5%). However, the mortality rate could only reach to 100% 96 h later while diatomite was used alone.更多还原
