The flight activities of adult sweetpotato whitefly, Bemisia tabaci, and leafhoppers were monitored by plastic cup traps at Boğalı, Taşçı, Hacıali, Doğankent and Balcalı in the Çukurova Plain, Turkey, in 2001 and 2003. Activity of B. tabaci, expressed as numbers of adults caught in traps, was low from May to early July in both years. Numbers of B. tabaci caught at Tasçı were higher than at Boğalı from 10 July and 21 August in 2001. Its numbers were also higher at Doğankent than at Hacıali and Balcalı during August of 2003. The numbers of leafhopper adults caught fluctuated greatly in both years. Numbers remained low until late June, followed by gradual increases in July and August at Boğalı and Taşçı in 2001. In contrast, numbers of adults caught were higher at Hacıali, Doğankent and Balcalı from May through July in 2003, followed by lower catches during the remainder of the season. Daily minimum temperatures in July and August were positively correlated with higher trap catches of both B. tabaci and leafhoppers.

Phlebotomine Sandflies

Previous work on Phlebotomines has shown that most parous flies in many species may be recognised by the dark residual secretion in the accessory glands; parity can be confirmed by inspection of ovarioles. In the present study 12 species of Lutzomyia were caught in forests near Belém, Brazil, mainly with rodent-baited oil-traps. Many females of the predominant species, L. flaviscutellata (Mangabeira), were parasitised by the protozoan Monocystis. Parous rates based on examination of ovaries were subject to an error of about 5% due to diminution or disappearance of follicular relics. Two successive dilatations of the tunica were seen in L. davisi (Root), suggesting that it had laid two batches of eggs. Biting rates by parous flies varied little during the night, and were somewhat less than those of nullipars. In eight species the dark-gland rate approximated to the parous rate as shown by the ovaries; a small error may have been due to discharge of all secretion, disappearance of follicular relics and premature activity of glands. In contrast to this concordant pattern, four species showed discordance, possibly due to autogeny. It seems advisable to omit oil-trapped blood-fed flies when estimating parous rates by examining glands. Monocystis may increase the dark-gland rate, but it is non-pathogenic or has little effect on life span, and does not hinder blood-sucking.

AbstractHolarctic expansion of Neoclytus acumiantus acuminatus due to its polyphagous character has been a major concern for plant health, which raises several questions about its spreading directions. I have examined all bibliographical references, phytosanitary reports and authentic photographs from the online sources in the quest of the determination of the worldwide distribution and flight phenology of N. a. acuminatus. The expansion, including the western Palearctic regions as well as several Neotropical habitats, is proven and has become more intense in the last decades. It can be found mostly on the Holarctic region including 21 countries, which is supported by 51 publications. Its spreading mostly northward and eastward in the Palearctic is continuous due to anthropogenic effects, climate change as well as movement of infested materials. Flight phenology and population densities as a function of habitats were mapped. The detection in novel habitats of this pest due to imported wood materials and products is envisaged in the foreseeable future. The primary criterion for controlling the species adapted to the commercial trade and climatic change would be the elaboration of a monitoring system in affected and exposed areas.

Objectives, 1. Determination of daily and seasonal movements of elk (Cervus elaphus). 2. Identification of vegetation and physiographic characteristics of habitats and/or habitat complexes used for feeding, cover, mating, and calving. 3. Determination of seasonal and yearlong range. 4. Identification of actual or potential damage to park resources (including structures, vegetation, and other animals) that could be attributed to introduction of elk. 5. Description of daily and seasonal activity and behavior patterns of elk. 6. Description of elk population changes during the study, and prediction of elk carrying capacity for each unit of Theodore Roosevelt National Park (TRNP).

The Galaxy

It is now possible to determine proper motions of high-velocity objects in such a way as to obtain with some accuracy the velocity vector relevant to the Sun. If a potential field of the Galaxy is assumed, one can compute an actual orbit. A determination of the velocity of the globular clusterωCentauri has recently been completed at Greenwich, and it is found that the orbit is strongly retrograde in the Galaxy. Similar calculations may be made, though with less certainty, in the case of RR Lyrae variable stars.

Sn 1987A

Using the new reductions of the IUE light curves by Sonneborn et al. (1997) and an extensive set of HST images of SN 1987A we have repeated and improved Panagia et al. (1991) analysis to obtain a better determination of the distance to the supernova. In this way we have derived an absolute size of the ringRabs= (6.23 ± 0.08) x 1017cm and an angular sizeR″ = 808 ± 17 mas, which give a distance to the supernovad(SN1987A) = 51.4 ± 1.2 kpc and a distance modulusm–M(SN1987A) = 18.55 ± 0.05. Allowing for a displacement of SN 1987A position relative to the LMC center, the distance to the barycenter of the Large Magellanic Cloud is also estimated to bed(LMC) = 52.0±1.3 kpc, which corresponds to a distance modulus ofm–M(LMC) = 18.58±0.05.

A symposium on the future of the International Latitude Service (I. L. S.) is to be held in Helsinki in July 1960. My report for the symposium consists of two parts. Part I, denoded (Mk I) was published [1] earlier in 1960 under the title “Latitude and Longitude, and the Secular Motion of the Pole”. Part II is the present paper, denoded (Mk II).
