The Amylases of Insects [PDF]

open access: yesInternational Journal of Insect Science, 2018
Alpha-amylases are major digestive enzymes that act in the first step of maltopolysaccharide digestion. In insects, these enzymes have long been studied for applied as well as purely scientific purposes. In many species, amylases are produced by multiple gene copies. Rare species are devoid of Amy gene.

Alkane biosynthesis gene expression and its increased production in recombinant cyanobacteria

open access: yesFEBS Open Bio, EarlyView.
The transcription and mRNA structures of the alkane biosynthesis genes ado/aar were analysed in the representative cyanobacteria PCC 6803 and SK1‐2‐1, which produce C17H36 and C15H32, respectively. PCC 6803 transconjugants carrying these genes showed a 1.8‐ to 2.3‐fold increase in C17H36 production.

Shared volatile organic compounds between camel metabolic products elicits strong Stomoxys calcitrans attraction

open access: yesScientific Reports, 2020
The sources of animal odours are highly diverse, yet their ecological importance, in host–vector communication, remains unexplored. Here, using the camel (host)–Stomoxys calcitrans (vector) interaction, we collected and analyzed the Volatile Organic ...

Detecting Invasive Insects with Unmanned Aerial Vehicles [PDF]

open access: yes, 2019
A key aspect to controlling and reducing the effects invasive insect species have on agriculture is to obtain knowledge about the migration patterns of these species. Current state-of-the-art methods of studying these migration patterns involve a mark-release-recapture technique, in which insects are released after being marked and researchers attempt ...

The city as a refuge for insect pollinators

open access: yesConservation Biology, 2017
Research on urban insect pollinators is changing views on the biological value and ecological importance of cities. The abundance and diversity of native bee species in urban landscapes that are absent in nearby rural lands evidence the biological value ...

Companion planting to attract pollinators increases the yield and quality of strawberry fruit in gardens and allotments [PDF]

open access: yes, 2020
1. Global pollinator declines have led to concern that crop yields might fall as a result of a pollination deficit. Companion planting is a traditional practice thought to increase yield of insect pollinated crops by planting a co-flowering species next ...
