Carbon dioxide (CO2) as a greenhouse gas has been increasing in recent decades. Because an elevated atmospheric CO2 influences insect physiology and behaviour, we hypothesize that pheromone-mediated communication in the moth is affected by an increased CO2 level. We test the behavioural responses of male Helicoverpa armigera to sex pheromone...
CAPA and pyrokinin (PK) neuropeptides are produced from two different genes, capa and pyrokinin, respectively. In this study, we identified and characterized the capa and pyrokinin genes from the brown marmorated stink bug, Halyomorpha halys (Hemiptera). The capa gene encodes two CAPA-PVK (periviscerokinin) peptides (DAGLFPFPRVamide and EQ-LIPFPRVamide) and one CAPA-DH...
As CMOS processes keep scaling down devices, the maximum operating frequencies of CMOS devices increase, and hence circuits can process very wide band signals. Moreover, the small physical dimensions of transistors allow the placing of many more blocks into a single chip, including highly accurate analog blocks and complicated digital...
A method for large quantity dsRNA production was developed since a small amount of dsRNA synthesized in vitro with commercial kits are used for small scale bioassay evaluations. Developing a large-scale production system for dsRNA is critical for practical RNAi application, especially for non-transgenic RNAi-based control. However, large-scale analysis or...
Many studies have shown that ground beetles feed on different agricultural pests, but little is known about their species communities from US cropping systems. We assessed the biological control potential of the most common carabid beetle species in Oregon annual ryegrass grown for seed by investigating spatial and temporal overlap...
Numbers of carabid beetles, caterpillars, cranefly larvae and slugs collected from pitfall and refuge traps in ten Annual Ryegrass fields in Linn County, Oregon between March 23, 2018 and June 20, 2019. Given are details on sampling date, trap, size and sex (carabids only), weight (slugs only) and species (where...
Mordenite and X- or Y-type faujasite were used to remove volatile organic compounds (VOCs) by adsorption at 25 °C. A microwave heating desorption system was applied for pollutant adsorbent regeneration. Studies were focused on the relationship between the adsorption and/or desorption behavior of selected VOCs (benzene, toluene, o-, m-, p-xylene,...
In this work, stainless steel wire cloth (SSWC) for metallic support was thermally treated to increase the adhesive strength of Al₂O₃ by improving superficial roughness. After coating Al₂O₃ on SSWC, Pt particles as a catalytic component were deposited on the Al₂O₃/SSWC. These supports and catalysts were characterized by N₂ gas...
Flowering is the primary trait affected by ambient
temperature changes. Plant microRNAs
(miRNAs) are small non-coding RNAs playing an
important regulatory role in plant development. In
this study, to elucidate the mechanism of
flowering-time regulation by small RNAs, we
identified six ambient temperature-responsive
miRNAs (miR156, miR163, miR169, miR172, miR398
and...
The cotton bollworm, Helicoverpa armigera (Hubner) is one of the most serious insect pest species to evolve resistance against many insecticides from different chemical classes. This species has evolved resistance to the pyrethroid insecticides across its native range and is becoming a truly global pest after establishing in South America...
