Demystifying fungal systematics: A gateway to fungal literacy and societal/ecological relevance through familiar species

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Fungal systematics can feel overwhelming given the vast species diversity within this kingdom, with numerous subgroups at every taxonomic rank. This often creates a disconnect between the undertsnidng of fungal taxonomic diversity and their societal relevance.

Ethyl formate diluted with nitrogen is an effective biosecurity treatment for brown marmorated stink bug (Halyomorpha halys)

open access: yesPest Management Science, EarlyView.
This research found that ethyl formate effectively controls adult brown marmorated stink bugs (Halyomorpha halys) regardless of dormancy state or temperature, at concentrations nine times lower than previous studies. Abstract BACKGROUND The brown marmorated stink bug (Halyomorpha halys) (BSMB) is a biosecurity threat globally. Its most likely avenue of

SYN‐A, a naturally derived synergist, restores pyrethroid efficacy against cabbage stem flea beetle but negatively impacts its parasitoid Microctonus brassicae

open access: yesPest Management Science, EarlyView.
SYN‐A, a naturally derived synergist, inhibited key metabolic pathways associated with pyrethroid insecticide resistance in cabbage stem flea beetle (CSFB) and its parasitoid Microctonus brassicae. SYN‐A restored pyrethroid efficacy against resistant CSFB allowing up to 80% reduction in application rates.

Effectiveness of botanical preparations for the control of rice weevil (Sitophilus oryzae) during rice seed storage and their impact on the rice seed viability : a thesis presented in partial fulfilment of the requirements for the degree of Master of Applied Science in Seed Technology at Massey University, Palmerston North, New Zealand [PDF]

open access: yes, 2001
Food security and the maintenance of seed quality from harvest to planting are key issues for peasant farmers. In Sierra Leone, up to 28% of rice seed can be damaged by rice weevil in the six months storage period.

Field investigation of glucosinolates and morphological traits in mitigating Psylliodes chrysocephala larval infestation through crop varieties and companion planting

open access: yesPest Management Science, EarlyView.
Genotype and cropping system influenced oilseed rape ecophysiological traits, including glucosinolate compounds (glucoraphanin, glucobrassicanapin, and butyl‐glucosinolates) and biomass, which were linked to Psylliodes chrysocephala larval infestation, with varietal effects stronger than faba bean companion planting.
