Abstract

A sand transport model using White's sand flux equation and the Mars beneral circulation model was developed to understand the erosional sources, transport pathways, and depositional sinks of windblown sand on Mars. An initially uniform distribution of sand (4 mm over the entire surface) is reeionally transported based on wind stress, saltation threshold, and percentage of topogaphic trapping. Results are consistsnt with the , observed polar and Hellespontus dunes and Christensen's madeled block size distribution, butonly for an extremely law saltation threshold (0.024 N/sq m): Low thresholds generally result in transport of sand-sized particles originating in the northern mid latitudes to the north pole, and transport from the northern lower latitudes to the southern hemisphere. Our results indicate that the polar dune fields could form in 50,000 years, consistent with the active polar dunes and lack of longitudinal dunes observed on the surface of Mars.

Abstract

Previous immunohistochemical studies combined with retrograde tracing in macaque monkeys have demonstrated that corticocortical projections can be differentiated by their content of neurofilament protein. The present study analyzed the distribution of nonphosphorylated neurofilament protein in callosally projecting neurons located at the V1/V2 border. All of the retrogradely labeled neurons were located in layer III at the V1/V2 border and at an immediately adjacent zone of area V2. A quantitative analysis showed that the vast majority (almost 95%) of these interhemispheric projection neurons contain neurofilament protein immunoreactivity. This observation differs from data obtained in other sets of callosal connections, including homotypical interhemispheric projections in the prefrontal, temporal, and parietal association cortices, that were found to contain uniformly low proportions of neurofilament protein-immunoreactive neurons. Comparably, highly variable proportions of neurofilament protein-containing neurons have been reported in intrahemispheric corticocortical pathways, including feedforward and feedback visual connections. These results indicate that neurofilament protein is a prominent neurochemical feature that identifies a particular population of interhemispheric projection neurons at the V1/V2 border and suggest that this biochemical attribute may be critical for the function of this subset of callosal neurons.

26. Sand transport on Mars: Preliminary results from models

Abstract

Most studies of active aeolian processes on Mars have focused on dust, i.e., particles approximately 1 micron in diameter that are transported in suspension by wind. The presence of sand dunes on Mars indicates that larger grains (approximately greater than 60 microns, transported primarily in saltation) are also present. Although indirect evidence suggests that some dunes may be active, definitive evidence is lacking. Nonetheless, numerous studies demonstrate that sand is substantially easier to transport by wind than dust, and it is reasonable to infer that sand transportation in saltation occurs under present Martian conditions. In order to assess potential source regions, transportation pathways, and sites of deposition for sand on Mars, an iterative sand transport algorithm was developed that is based on the Mars General Circulation Model of Pollack et al. The results of the dust transport model are then compared with observed surface features, such as dune field locations observed on images, and surficial deposits as inferred from Viking IRTM observations. Preliminary results suggest that the north polar dune fields in the vicinity of 270 degrees W, 70 degrees N originated from weathered polar layered plains centered at 280 degrees W, 85 degrees N, and that Thaumasia Fossae, southern Hellas Planitia, and the area west of Hellespontus Montes are sand depositional sites. Examples of transportation 'corridors' include a westward pathway in the latitudinal band 35 degrees N to 45 degrees N, and a pathway southward from Solis Planum to Thaumasia Fossae, among others.

27. TRIALS FOR THE CONTROL OF THE CITRUS MEALYBUG IN CITRUS ORCHARDS BY AUGMENTATIVE RELEASE OF TWO ENCYRTID PARASITOIDS

Abstract

TRIALS FOR THE CONTROL OF THE CITRUS MEALYBUG IN CITRUS ORCHARDS BY AUGMENTATIVE RELEASE OF TWO ENCYRTID PARASITOIDS. Since the 1980s, the citrus mealybug Planococcus citri (Risso) has become a key pest in Israel, owing to intensive planting of highly susceptible varieties, the introduction of Insect Growth Regulators (which adversely affect coccinellids) and the development of resistance to chlorpyrifos. Management of the mealybug populations in citrus orchards by augmentative releases of parasitoids was investigated between 1993 and 1996 in a series of tests involving the release of 5,000-10,000 Leptomastix dactylopii (Howard) (Encyrtidae) per hectare. Results showed no significant effect on the density of the mealybug on the fruits. In general, the establishment of L. dactylopii was poor and population levels were inferior to those of the naturally occurring Anagyrus pseudococci (Girault) (Encyrtidae). In 1996-1997, augmentative early-spring releases of A. pseudococci at the rates of 10,000-50,000 individuals per hectare markedly increased the population density of A. pseudococci during April and June but had no significant effect on either the mealybug infestation or on fruit damage caused by the pest and its fruit moth associates.

28. THE CITRICULUS MEALYBUG, PSEUDOCOCCUS CRYPTUS HEMPEL, AND ITS NATURAL ENEMIES IN ISRAEL: HISTORY AND PRESENT SITUATION

Author

Blumberg, D., Ben-Dov, Y., and Mendel, Z.

Abstract

THE CITRICULUS MEALYBUG, PSEUDOCOCCUS CRYPTUS HEMPEL, AND ITS NATURAL ENEMIES IN ISRAEL: HISTORY AND PRESENT SITUATION. The citriculus mealybug, Pseudococcus cryptus Hempel, was first discovered in Israel in 1937 and very rapidly became a key pest of citrus. However, since the early 1940s, the mealybug population has sharply decreased. This occurred in parallel with the establishment of the introduced parasitoid Clausenia purpurea Ishii, which was then believed to be the main cause of the biological control of the mealybug. Since the late 1980s, outbreaks of P. cryptus have been recorded mainly in new citrus varieties, such as red grapefruits, pomelo, “sweety” and several peeling varieties. The current outbreaks are probably related to the susceptibility of these mentioned varieties to P. cryptus, and to the adverse effects of Insect Growth Regulators to coccinellid predators, especially Scymnus spp. The introduced C. purpurea and two other local encyrtid parasitoids, Leptomastix near algirica and Anagyrus diversicornis Mercet, rarely emerged from samples of P. cryptus collected during 1996-1998. Four further parasitoid species were introduced into Israel during 1996-1997 against P. cryptus: from central Asia, the platygasterids Allotropa burrelli Muesebeck and A. convexifrons Muesebeck and the encyrtid, Pseudaphycus malinus Gahan; and from Japan, Anagyrus sawadai Ishii. A. convexifrons and A. sawadai successfully parasitized P. cryptus and, therefore, were released in the field but only A. sawadai has so far been recovered. A considerable reduction in population densities of the pest has been recorded since May, 1998, in the major release site of the latter species. Key words: distribution, host plants, Pseudococcus comstocki, P. citriculus, P. viburni, IGR, Coccinellidae, Planococcus citri, P. ficus, Aonidiella aurantii, Ceroplastes floridensis, Anagyrus pseudococci, Leptomastidia abnormis, Leptomastix flavus, Cryptolaemus montrouzieri, Cecidomyiidae, Sympherobiidae, Chrysopidae., Entomologica, Vol 33 (1999)

Abstract

The interaction between wind and desert surfaces has important implications for sediment transport on Earth, Mars, and Venus, and for understanding the relationship between radar backscatter and aerodynamic roughness. Here, researchers report results from measurements of atmospheric boundary layer profiles, assessment of radar backscatter at P, L, and C wavelengths, and surface roughness in Death Valley, the Mojave Desert, and Lunar Lake, NV, and discuss the implications for aeolian process. The sites include playas, gravel and sand regs, alluvial fans, and lava flows. Boundary layer wind profiles were measured using anemometers at heights of 0.75, 1.25, 2.07, 3.44, 5.72, and 9.5 m; temperature sensors at heights of 1.3 and 9.6 m; and wind vanes at 9.7 and 1.5 m. Microtopographic measurements were made using a template and a laser-photo device to obtain RMS height. This study demonstrates that radar backscatter coefficients obtained from airborne and perhaps orbiting instruments could permit the derivation of aerodynamic roughness values for large areas. Such values, when combined with wind frequency data, could enable assessment of aeolian processes on a regional scale.
