中国甲螨名录(Ⅰ)(蜱螨亚纲:甲螨亚目)

Preface The research on Chinese oribatid mites was started in the 1920's, when A. Jacot recorded 10 oribatid species from Beijing (Peking) and Shandong (Shantung). In the 1980s', Chinese acarologists noticed the necessity of studying soil mites, which were poorly investigated and reported during the past 60 years. Along with the adoption of more open policy in China, the academic exchange and coopera

MORPHOLOGY OF THE IMMATURE STAGES OF DACUS TRYONI (FROGGATT) (DIPTERA: TEPHRITIDAE)

Abstract
External features of the puparium, larvae and egg of the Queensland fruit fly, Dacus (Bactrocera) tryoni (Froggatt) were studied by scanning electron microscopy and significant morphological characters are described and illustrated. Cephalopharyngeal skeletons are described from examination by light microscopy.     

INTRA-POPULATION VARIATION OF THE SHELL OF LITTORINA RUDIS (MATON) (MOLLUSCA: PROSOBRANCHIA)

Shell variation within a single population of Litlorina rudis(Maton), collected near the Biological Station at Trondheim,Norway, was studied. The variation of the shell features studied, which includedthe shape of the basal part of the outer lip, and the relativeheight of the spire, width of the shell and of the aperture,were found to be at least partially related to shell height.Furthermore, the shell shape in the population investigated,besides varying with age, also varies due to shell damage. Nosignificant differences were found between the shapes of theshells of males and females. The shell characteristics of different populations of L. rudisalso vary greatly, one of the causes being differences in theenvironmental conditions. When studying this variation betweendifferent populations, however, it must be emphasized that onlyundamaged shells of individuals of about the same age shouldbe compared, in order to obviate the effects of the variabilitydue to age differences and shell damage within each individualpopulation. ^*Contribution from Trondhjem Biological Station no. 199 (Received 18 February 1980;

INFLUENCE OF WEATHER ON TRAP CATCHES OF CHRYSOMYA RUFIFACIES (MACQUART) (DIPTERA: CALLIPHORIDAE)

Abstract
Adult populations of the hairy maggot blowfly, Chrysomya rufifacies were sampled 6 times daily between dawn and dusk on 35 occasions during 1984/85 at Murrumbateman, New South Wales, using wind-oriented fly traps. Temperature, solar radiation and relative humidity explained 74.3, 8.8 and 1.6% of the within-day deviance of catches. Flies did not enter traps unless the temperature exceeded 13°C. Above 13°C, log catch increased linearly up to 23°C and remained constant thereafter up to the maximum temperature recorded (37°C). Catch rates were unaffected either by wind speed or time of day. Weather effects also explained 87.5% of the between-day variation in daily catches. Standardized catches of C. rufifacies indicate that at Murrumbateman, C. rufifacies numbers peak in autumn and that unstandardized data may not truly reflect seasonal changes in fly numbers.

THE POPULATION OF A LARGE MOUND OF NASUTITERMES EXITIOSUS (HILL) (ISOPTERA: TERMITIDAE)

i
More than 2.5 million termites, weighing 11.05 kg, were obtained from a mound colony of Nasutitermes exitiosus (Hill). Because of the unusually large size of the colony examined, and the favourable conditions that were experienced for extracting the termites, it is thought that this figure is close to the upper limit of nest population attained by this termite.
