Analysis of Critical Instability Conditions for Solid-Phase Plugging of Natural Fractures during Temporary Plugging and Fracturing.

Hydraulic fracturing has become a key technology for the development of unconventional oil and gas resources, such as deep shale. Due to the development of natural fractures in deep shale reservoirs, the opening of natural fractures during the fracturing process can cause a significant loss of fracturing fluid, resulting in a reduction in the width of the main fracture and construction risks, such as sand plugging. It is important to improve the fracturing effect of deep shale reservoirs by plugging natural fractures with solid phases, reducing filtration, and improving the efficiency of the fracturing fluid.

Coding and Non-coding RNAs: Molecular Basis of Forest-Insect Outbreaks.

Insect population dynamics are closely related to 'human' ecological and economic environments, and a central focus of research is outbreaks. However, the lack of molecular-based investigations restricts our understanding of the intrinsic mechanisms responsible for insect outbreaks. In this context, the moth Walker can serve as an ideal model species for insect population dynamics research because it undergoes periodic outbreaks.

New technology for using meteorological information in forest insect pest forecast and warning systems.

Background: Near surface air temperature and rainfall are major weather factors affecting forest insect dynamics. The recent developments in remote sensing retrieval and geographic information system spatial analysis techniques enable the utilization of weather factors to significantly enhance forest pest forecasting and warning systems. The current study focused on building forest pest digital data structures as a platform of correlation analysis between weather conditions and forest pest dynamics for better pest forecasting and warning systems using the new technologies.

Sensilla on different organs of female and male Telenomus dendrolimusi Chu (Hymenoptera: Scelionidae).

Telenomus dendrolimusi Chu is a dominant egg parasitoid of Dendrolimus, which is the most serious conifer defoliator in China. However, the host locating mechanism of T. dendrolimusi is unclear.

Structural characteristics and phylogenetic analysis of the mitochondrial genome of the rice leafroller, Cnaphalocrocis medinalis (Lepidoptera: Crambidae).

The rice leafroller, Cnaphalocrocis medinalis, is one of the most important pests on rice and possesses striking flight ability. We have determined the nucleotide sequence of the 15,377 bp of a C. medinalis mitochondrial genome (mtDNA).
