...group of biologists including Carpenter, Mayr, and Philip J. Darlington, Jr., Alexander Agassiz Professor of Zoology, urged B and G to stop spraying the ivy long enough to allow the moth's natural predators and parasites to return...
...moth's enemies, including a parasitic wasp that lays its eggs on the caterpillars, have apparently staged a comeback. And many biologists suspect that the new ivy around the Bio Labs is less moth-eaten than the sprayed ivy in the Yard and Business School areas...
...moth population remains in check this year, the biologists may suggest a de-escalation of the ivy moth war elsewhere in the University...
...state entomologist at the Shade Tree Laboratory Field Station in Waltham suggested that a commercial preparation of the bacterium Bacillus thuringiensis might keep the moth population down for several years while the natural predators re-establish themselves. This particular biological control has recently halted the cabbage looper and fruit cankerworm, but it has not been tried against the ivy moth...
INSECTICIDES have created a particular problem for entomologists at the Bio Labs. When an organic phosphate insecticide was sprayed in the Laboratory's greenhouse last year, it drified into a ventilation fan and wiped out a colony of silk moths in another room. Ironically, these moths were part of a study on moth development and hormones-a project that may lead to a safer class of insecticides...
