The present paper deals with the third stage larvae of synanthropic flies col-lected from Shanghai District. A general key is given, comprising 31 identifiedspecies and several undetermined species. The latter are keyed to the family orgenus only. The larvae of Fannia prisca Stein, Ophyra chalcogaster (Wd.), and the pupaeof Graphomyia rufitibia Stein, and Musca convexifrons Thoms. are described for thefirst time. 1. Fannia prisca Stein (fig. 2) Third stage larva: The sculptures of the cuticle of the ventral side of theabdominal segments are scale like, those on the posterior one fourth being moreregular. On the same side of segments IV-VII are 2 large non-pediculate strawberrylihe sub-lateral processes, in addition to 6 small ones transversely arranged nearthe posterior border of each segment. The basal portion of the marginal fleshyprocesses of the 8th abdominal segment are provided with bifurcated short branches.The anterior spiracle possesses 9 finger-shaped processes radiating in a fan-likemanner. The pediculate posterior spiracle is provided with 3 rather long processes,on the tip of which the spiracular slit opens. These characteristics when used incombination are sufficient to distinguish this species from F.canicularis (L.) andF. scalaris (F.). In nature, the larvae are chiefly found in decaying Vegetable matter, such asheaps of vegetable leaves in garden or in garbages; occasionally they occur on de-caying animal matter as well as animal and human feces. In the laboratory, thelarvae can be reared easily in dregs from bean curd manufacture. 2. Graphomyia rufitibia Stein (figs. 3, 4) Pupa: Puparium brown, spindle shaped, tapering on both ends. Posterior surfaceof 8th abdominal segment very small, with 3 pairs of posterior processes. Posteriorspiracles small, elliptical, with spiracular slits slightly sinuous and subparallel toeach other. In the anal region are 2 anal, 2 subanal, 2 extra-anal tubercles and asingle preanal protuberance. With the exception of the anal tubercles the remainingtubercles and protuberance are provided with minute spines. Anal plate rather small,the lateral portion gently bent backwards. Anterior spiracle with 5 rounded digits.The general appearance of the bucco-pharyngeal apparatus is similar to the Phaonia type. Egg: The egg has broad dorsal flanges, which run nearly parallel, well separa-ted to each other, and with a bluntly serrated margin. This also suggests that thegenus Graphomyia is closely related to phaoniine flies. The pupae were found twice in garbage heaps. 3. Ophyra chalcogaster (Wd.) (fig.6) Third stage larva: Resembles to O. leucostoma (Wd.), but differing in the fol-lowing points: Anterior margin of the anal plate rounded and oblique to theposterior border of the segment before it, but the posterior margin is curved in-wardly, with the effect that the endings of the plate are directed slightly caudad.In O. leucostoma (Wd.), however, both the anterior and the posterior margins of theanal plate run parallel to the segment border. Near the posterior border of theabdominal segments are 1-2 rows of closely set series of minute spinules. In O.leucostoma (Wd.), these spinules are larger and are irregularly arranged. The larvae breed chiefly in feces of domesticated birds or animals and also ingarbages. 4. Musca convexifrons Thoms.(fig.9) Pupa: Puparium brownish grey. The posterior spiracles are heavily chitinizedwith much sinuously convoluted spiracular slits. There are no spinules along thedorsal grooves of the 8th abdominal segment. The lateral portion of the anal plateis square shaped. On the ventral pads of the abdominal segments is a row of largespines, which is interrupted in the middle. On each side of the row are smallerspines arranged in 2 definit rows arteriorly, but are arranged irregularly posteriorly.Anterior to the anterior margin of the anal plate below the square shaped lateral.portion is an isolated single row of minute spines. As a whole the characteristics as given above are very similar to those givenby Zimin (1948) for the larva of M. larvipara Portsch. In fa

1. The present paper is a preliminary report on the biological investigationof chiggers infesting chicken during 1954-1956. 2. According to our investigation, together with all the avallable literature onthe subject, 6 species, in 2 genera, of chicken chiggers have so far been recordedin this country. Among them, Neoschongastia gallinarum is widely distributedin Fukien, Chekiang, Anhwei, Taiwan, Shantung, Honan, Kiangsu, Hupeh, Kiangsi,Szechwan and Shanghai. Trombicula deliensis was found in Yunnan and N. posekanyi,N. americana solomonis were found only in Fukien, whereas Trombicula akamushiand T. corvi were accidentanlly discovered in Taiwan. With the exception of therecord from Kiangsu and Anhwei Provinces, the above-indicated distribution ofN. gallinarum, N. posekanyi, N. americana solomonis on the Chinese mainlandis supposed to be the first report made. 3. As the external parasites of birds, N. gallinarum, N. posekanyi, and N.americana solomonis possess no strict host-specificity, they have commonly beenfound as natural parasites of different species of wild and domestic birds in thecourse of our 2 years' survey. However, the discovery of the common magpie(Picapica sericea), siberian black-billed dipper (Cinclus pallaci), silver pheasant (Lophuranycthemera rufipes), golden pheasant (Chrysolophus amherstiae), big-billed crow(Corvus macrorhynchus), common turkey (Meleagris gallopavo), burmese pea-fowl(Pavo muticus imperator) and eastern turtle dove (Streptopelia decaocto) as naturalhosts of N. gallinarum, and the common turkey as the natural hosts of N. pose-kanyi, are new records. With the exception of the common turkey, it should beemphasized that reports regarding other birds as natural hosts of chiggermitesand the infestation of N. posekanyi and N. americana solomonis among domesticfowls has been vague in literature. 4. Attempts have been made to discuss the sources and factors of infestation,breeding place, distribution, disease relations and damages of N. gallinarum. 5. A preliminary observation of the seasonal distribution of N. gallinarum wasmade and it was found that in East China the difference is not very conspicuous.They are distributed between March and December, being more active and causingmuch damage during June to October. 6. Due to the peculiar characteristics of the pathological picture caused by thebite of the chicken chiggers, the name--"Chicken Chigger Pox"--is herewithproposed for this infestation to distinguish it from viral-borne chicken pox. 7. The damage caused by the chicken chiggers is always very serious in thiscountry, and yet very little attention was paid by the veterinary workers in protectingchickens against the infestation. The present paper emphasize the importance offurther and more intensive study of the mite, especially in the course of our nation-wide socialistic transformation.

Department of parasitology, First Shanghai Medical College The damages that chickens and other poultry suffer from the infestation of Neoschongastia gallinarum larvae are quite serious. It has been found, according to our surveys made since 1954, that N. gallinarum is widely distributed in this country and the infestation rate among the fowls and other land birds is very high. The present paper is a preliminary report on the study of the effects of temperature and moisture on the viability of N. gallinarum larvae under the conditions established in the laboratory. N. gallinarum larvae persist to live: (1) 18±1℃ & RH 73% for 26 hours and 20 minutes; (2) 26—29℃ & RH 50—52% for 12 hrs.;(3) 34±1℃ RH 50% for 9 hours; (4) 40±1℃ & RH 45% for 5 1/2 hrs.; (5) 45±1℃ & RH 37% for 2 hrs. and 40 mins.; (6) 50±1℃ & RH 34% for 100 mins.; (7) 56±1℃ & RH 30% for 40 mins.; (8) 61±1℃ & RH 28.5% for 10 mins. Besides, when kept in water, unengorged A. gallinarum larvae were found to survive in the temperature of 28±1℃, 34±1℃, 40±1℃, 50±1℃, 56±1℃, 61±1℃, 65±1℃; for 77 days, 29 days, 26 days, 10 hrs., 40 mins., 40 mins, and 20 mins, respectively. Furthermore the development of the larva to nymphal stage was observed in the above stated temperature especially in the temperature below 40±1℃. N. gallinarum larvae is comparatively resistant to freezing temperature. It is viable in temperatures of 0℃, -5℃, -10±1℃ for 32, 23 and 3 days respectively. With reference to the adaptation of the N. gallinarum larvae toward sudden changes of temperature, the distribution, the epidemiology, as well as the prevention of the "chicken chigger pox" are concisely discussed in this paper.
