Notes: Since 1990, the integrated control of walnut pests has been practised in Lulong county, the leading walnut producing area of Hebei province. The main pests in the area are Cnidocampa flavescens, Atrijuglans hetaohei, Botocera horsjieldii [Batocera horsfieldi] and Drosicha corpulenta. Trials showed that integrated control should include: (1) dusting 25% parathion in micro-capsule form or 5% phoxim on the ground before the soil freezes in winter; (2) painting a mixed solution of 1 kg 40% omethoate + 5 kg mineral oil; (3) spraying a 300-times solution of BT [Bacillus thuringiensis] or a 2000-times solution of 20% fenpropathrin from mid February to mid March for control Drosicha corpulenta nymphs and from mid June to early July for control of Atrijuglans hetaohei.
