Apanteles heterusiae Wilkinson is a major larval parasitoid of Diaphania pyloalis Walker in Zhejiang, China. In this paper, the biological characteristics of A. heterusiae are reported. Under the natural conditions of Zhejiang, its average rate of parasitism was about 16.8% from 2000 to 2002. The li...

The COVID-19 pandemic has caused a profound interruption in the way people travel and has had a very negative impact on tourism and economics throughout the world, especially on the coastal fishing communities in South Korea. These previously problematic areas, having suffered a decrease in the loca...

Nonalcoholic fatty liver disease (NAFLD) is characterized by excessive hepatic fat accumulation and is closely associated with obesity, diabetes, and hyperlipidemia.

Abstract As physics‐based global magnetosphere‐ionosphere‐thermosphere models enter operations for space weather forecasting, it is imperative that the sources of uncertainty in model outputs are thoroughly investigated. Global magnetosphere models rely on a set of input solar wind conditions to dri...

In order to improve the surface strength of SCX400 wheel steel, ultrasonic rolling technology was used to strengthen the surface. The pressure parameters were optimized by means of experimental test. Results showed that increasing the ultrasonic rolling pressure was helpful to obtain the deformation...

Hyperspectral images contain rich information of ground objects and the technology is widely used in many occasions. Since each classification model has different classification performance, effectively utilizing the difference in the performance of each classification model is an essential step...

The underground runoff caused by precipitation in the mountain area erodes the fragile soil structure, which leads to the uneven settlement of the base of the high-voltage tower in this area, which poses a serious hidden danger to the safety of the transmission line. We use ground penetrating radar...

CBT cells from colossoma brachypomum and CP cells from eurythermic grass carp were induced with intimidated cold temperature (10℃ and 4℃ respectively) for 0-8 days. Using FT-IR technique, relative contents of the cells were determined, including DNA, RNA, protein, phosphates and glucose. In this way...

Pollen grains of 17 mustard subspecies were examined under scanning electron microscope. The result showed that the pollen shapes were nearly spherical, or spheroidal, or super-spheroidal from the equatorial view, depending on cultivars of mustard. The size of pollen grain showed great variation amo...

Extractive efficiency of several extractants of Bt toxic protein from Bt transgenic rice was studied by orthogonal experiments. The results showed that the extractants and extracting conditions have similar efficiency for Bt toxic protein and the total proteins of the transgenic rice. The solutions...

Respiration rates in insects are critical for survival and environmental adaptation, being influenced by developmental stages, environmental conditions, and the regulation of mitochondrial protein-coding genes. However, methods for field-based measurements in small-sized insects remain limited. In t...
