An insect trap constructed in the form of a box having an open front end and a removable top. Disposed within the box is a ramp having an upwardly rising domain and a downwardly declining domain, the rising domain being disposed at an angle of between 125° and 165° from the declining domain. The box, removable top and ramp elements are fabricated from a material which provides a smooth and slippery surface. A traction-providing substrate is disposed over the rising domain of the ramp, thereby enabling insects to contact and crawl up the rising domain. In operation, insects enter the open front end of the box, crawl up the rising domain, slide down the declining domain and drop to the floor of the box where the insects remain trapped.

Apparatus for and a method of rotating microscopic objects uses a beam of electromagnetic radiation. A microscopic, non-circularly symmetric distribution of electro-magnetic radiation is projected on to a region containing an object to be rotated so as to cause photons in the beam to refract around the objects. Rotating means then rotate that distribution and so rotate the objects. The distribution may be formed on the interference pattern between a beam having a Laguerre-Gaussian wave fronts and either a plane wave or a further Laguerre-Gaussian beam of opposite helicity.
