ABSTRACT Functional properties of protein concentrates from alfalfa leaves (ALP) prepared by several methods were determined. Minimum solubilities occurred around pH 3.5–4; sodium chloride 0.05–0.2M had little effect on minimum solubility. Extraction the lipids ALP with acetone decreased solubility slightly; increased bulk density (2‐3‐fold); and reduced water fat absorption capacities 50% compared to controls. Both emulsifying activities emulsion stabilities samples generally better than...

The blue-gum chalcid Leptocybe invasa Fisher & LaSalle (Hymenoptera: Eulophidae) is a gall wasp pest of Eucalyptus species, likely native to Australia. Over the past 15 years it has invaded 39 countries on all continents where eucalypts are grown. worldwide invasion blue gum was attributed single thelytokous morphospecies formally described in 2004. Subsequently, however, males have been recorded several and sex ratio field populations found be highly variable different areas. In order find...

ABSTRACT Alfalfa leaf proteins extracted with sodium chloride (1M), hydroxide (0.05M) or Tris buffer (0.1M) had poor foaming properties compared to obtained by direct expression of juice. Extraction lipids from all protein extracts markedly improved both foam formation and stability. Foam expansion alfalfa surpassed that ovalbumin but the was less stable. The pH profile resembled solubility pattern this protein. delipidated preparations showed little effect being rather constant between...

Euplatypus parallelus (Coleoptera: Curculionidae) is a neotropical ambrosia beetle that rapidly spreading around the world. It has been recorded from over 80 host trees and implicated as primary pest attacking rubber rosewood. Here, we report first country record successful establishment of species in Hainan, China. Currently, E. does not appear to act destructive forest Hainan.

The complete mitochondrial genomes (mitogenomes) of beetles in the tribe Scolytoplatypodini (genus Scolytoplatypus) were sequenced and annotated. These included Scolytoplatypus raja (15,324 bp), sinensis (15,394 skyliuae (15,167 wugongshanensis (15,267 bp). four mitogenomes contained 37 typical genes, including 13 protein-coding genes (PCGs), 22 transfer RNA (tRNAs), 2 ribosomal (rRNAs). gene orientation arrangement similar to other Coleoptera mitogenomes. PCGs mostly started with ATN...

Abstract The sweetgum inscriber (SI) Acanthotomicus suncei Cognato is an emerging bark beetle pest that seriously damages American trees ( Liquidambar styraciflua ) and Chinese L. formosana in China. Since 2013, SI has killed more than 30,000 Shanghai adjacent areas. In Shanghai, was observed to emerge from infested wood between April–September exhibited two generations per year. Both the flying populations those colonized logs were female‐biased. After parental adult initiates a gallery,...

In Indonesia, Pinus merkusii, the Sumatran pine, is most important forest tree in industry. This study aimed to determine effects of pine types and sites on abundance ambrosia beetles four sites, i.e., protected (PF1 & PF2), forests-based agroforestry (PA1 PA2), tapped-pine forests (TP1 TP2), non-tapped (NP1 NP2). The environmental variables stand-ages were also studied related number beetle individuals species. Twenty ethanol baited traps installed attract collect each site. descriptive...

Abstract Growth of brown planthopper (BPH) ( Nilaparvata lugens Stål) in rice paddies is mainly driven by meteorological factors under similar management practices. By analyzing field investigation and data collected from 2008 to 2013 Nanchang, China, we show that BPH population densities monthly growth rates (BGR) changed greatly May October, these changes were closely associated with factors. Stepwise regression path analysis indicated average speed winds (AW) June lowest temperature (LT)...
