A dust-acoustic-drift wave instability is investigated in a nonuniform collisional dusty magnetoplasma. The plasma parameters are such that the electrons are magnetized, while the ions and dust grains are collisional and nonmagnetized, which may be characteristics of dusty plasmas in the E region of the Earth's ionosphere. The instability is driven by electron E ¿ B and diamagnetic drifts. Possible application to the edges of dusty meteor trails at altitudes >95 km is considered. It is shown that this instability could be driven by an electron cross-field drift smaller than the ion thermal speed in a meteor trail containing a sufficient charge density of positively charged dust.
