The Mosquitoes of New Jersey III Control of the Swamp-Mosquito Group The control of this group differs from that of the house group, and drainage must necessarily play a large part. Breeding occurs over much larger areas where larvicides could be only slightly effective. Furthermore, M. pcrturbans can not be killed with oil because neith- er larvae nor pupae come to the surface for air. Nothing but a substance that mixes with the water can be successfully used.

The type of inspection necessary to find breeding of this species is rad- ically different. One must pull up the tussock-forming grasses growing in the suspected place and look for the larvae fastened to the roots. Sometimes the larvae can be scraped off the mud with a dipping net after the tussock grass has been pulled away. /«-l\f'? !V ! / ^ il-^. Fig. 70. Typical breeding place of the Woodland-Pool Mosquito. The IVoodland-Pool Mosquito Group This, like the swamp group, is somewhat loosely defined, for cer- tain species that generally breed in woodland pools, under some conditions, breed in more open places. In general, however, the woodland group winters in the tgg stage, produces a large brood early in the season, and stays close to the place where larval life was passed. Man is troubled by them only as he builds nearby or oth- erwise penetrates their haunts when they are on the Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original New Jersey Agricultural Experiment Station.
