DEPARTMENT OF AGRICULTURE The phycitid moth Tlascala finiteUa (Walk.) was first collected in 1932 from hogsheads of flue-cured tobacco in Richmond. Occasional specimens have been observed since that date in warehouses of cigarette tobacco. A number of other species of insects have been found in stored tobacco, none of which are considered to be of appreciable economic importance. The larva of the moth Aglossa sp. (presumably cupre- alis (Hbn.)) feeds on tobacco in a molded and partly decayed con- dition and is sometimes found in warehouses. The following species, listed about in the order of their abundance, have been found in tobacco: Tribolium confusum Duv., Henoticus serratus (Gyll.), Ahas- versus advena (Waltl), Typhaea stercorea (L.), Anthrenus verbasci (L.), Lepisma saccharina L., Ptinus ~brwmeu& Duft., Attagenus piceus (Oliv.), and Trogoderma sp. Some of these insects probably act- as scavengers, eating the dead bodies of the cigarette beetle and the tobacco moth, whereas others use the tobacco as a temporary Figure 9.—The chalcid Aplastomorpha calandrae, a parasite of cigarette beetle larvae. Greatly enlarged. (From Cotton.) NATURAL ENEMIES OF STORED-TOBACCO INSECTS The cigarette beetle and the tobacco moth have a number of im- portant natural enemies. The little chalcid wasp Aplastomorpha calandrae (How.) (fig. 9). which is a parasite of the larval stage of the cigarette beetle, is often found in abundance in connection with large populations of the beetles. Several factors make it unlikely that this parasite is an important factor in controlling infestations of the cigarette beetle. In tightly packed tobacco the adult females find it difficult to enter feeding tunnels of larvae. The parasites are very vulnerable to fumigants and other methods of control of the beetle and to low temperatures in winter. The predac
