Barriers with Valve Mechanisms Are Predicted to Protect Crops from Slug Carriers of Rat Lungworm Disease by Genevieve C. Pang, Amy T. Hou, Ryan Tamashiro, Kristin M. Mills, Lorrin W. Pang

“…We explored the application of barriers with valve mechanisms, whereby selective directional forces caused a greater number of slugs to exit than enter the protected plot, leading to decreased slug population densities at a steady state. Using field data, we constructed predictive models to estimate slug population densities at a steady state in protected plots with (1) no valve effect, (2) a valve effect, (3) no valve effect with a single breach of the barrier, (4) a valve effect with a single breach of the barrier, (5) a valve effect with a constant breach of the barrier, and (6) a repelling effect. …”

The effects of market integration on regional energy efficiency and mechanism by ZHANG Congcong, CUI Songtao, ZHU Zhishuang, ZHANG Huaming

“…[Results] The study found that: (1) Market integration can effectively promote regional energy efficiency, and the improvement of scale efficiency and technological progress are the key paths of market integration improving energy efficiency. (2) Market integration is more likely to improve energy efficiency in regions with high innovation levels and high population densities, and for regions with weaker innovation bases and lower population densities, the development of market integration can take the lead in improving regional scale efficiency and technological progress. (3) Market integration is more likely to improve regional energy efficiency by promoting the agglomeration of productive services. (4) Market integration can help alleviate the disparity of energy efficiency between regions. …”

Monoxenic rearing of Ditylenchus weischeri and D. dipsaci and microplot examination of the host suitability of yellow pea to D. weischeri by Abolfazl Hajihassani, Mario Tenuta, Robert H. Gulden

“…While it had no impact on pea grain yield, D. weischeri slightly reduced plant height, aboveground biomass, and pod length at the population densities of 1600 and 3200 nematodes/plant. The final population densities at harvest were not significantly different from the initial densities indicating the pea varieties were poor hosts to D. weischeri. …”

Changes in the Sexual Dimorphism of Triatominae in the Transition from Natural to Artificial Habitats by JP Dujardin, M Steindel, T Chavez, M Machane, CJ Schofield

“…This feature is discussed in terms of genetic and populational changes occurring from natural to artificial habitats, in particular those related to population densities. Sexual size dimorphism is then recommended as a new character to be used in the study of species of Triatominae adapting to domestic ecotopes.…”
