The effects of methyl parathion on the colony dynamics of Apis mellifera : a thesis submitted in partial fulfilment of the requirements for the degree of Master of Science in Ecology at Massey University, Palmerston North, New Zealand [PDF]

open access: yes, 2000
The detrimental effects of pesticides to honey bee colonies were assessed using a combination of electronic and manual sampling techniques. Initial experiments determined that electronic bee counters could be used to identify and monitor toxic events ...

An integrated social and natural sciences case study for the reuse of organic wastes as soil amendments

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Reusing organic waste materials, such as animal manure, as soil amendments reduces water and fertiliser demand, contributing to achieving the Sustainable Development Goals. However, organic wastes may contain contaminants of emerging concern (CECs), posing potential ecosystem and human health risks. Despite the importance of this issue, there is a lack

Effects of bioinsecticide exposure route on aphids and their natural enemies in oilseed rape

open access: yesPest Management Science, EarlyView.
Fatty acids, silicone polymers and surfactants reduced aphid numbers but caused natural enemy mortality under direct exposure, while minimal residual activity suggests potential for targeted, compatible use in integrated pest management. Abstract BACKGROUND Myzus persicae Sulzer and Brevicoryne brassicae L.

Biochemical mechanisms of organophosphate and pyrethroid resistance in red hairy caterpillar Amsacta albistriga (Lepidoptera: Arctiidae)

open access: yesJournal of the Saudi Society of Agricultural Sciences, 2013
The red hairy caterpillar, Amsacta albistriga Walker, is an important pest of groundnut, castor and cotton in India. We determined the susceptibility of Amsacta albistriga to organophosphate and synthetic pyrethroid insecticides under laboratory ...

Federal Regulation of Pesticide Residues: A Brief History and Analysis [PDF]

open access: yes, 2019
In the United States today, there are over 900 pesticides in use1 and over 400 are approved for use in food production, whether used as part of the growing process or in post-harvest handling. Although the history of pesticide use in food crops goes back

Gene‐specific double‐stranded RNAs induce mortality in the South African mealybug Delottococcus aberiae

open access: yesPest Management Science, EarlyView.
Gene‐specific double‐stranded RNAs effectively silence essential genes in the invasive citrus pest Delottococcus aberiae, leading to significant mortality through both microinjection and oral delivery. These results provide proof of concept for RNA interference‐based biopesticides as selective and sustainable tools for citrus integrated pest management.

Susceptibility of Phthorimaea absoluta (Meyrick) (Lepidoptera: Gelechiidae) to novel and established insecticides in Brazil: resistance survey, baseline, and implications for management

open access: yesPest Management Science, EarlyView.
Baseline susceptibility of Phthorimaea absoluta to novel insecticides isocycloseram and tolfenpyrad was established in Brazil. Diagnostic doses were proposed for early resistance detection. Early tolfenpyrad tolerance and abamectin‐driven cross‐tolerance to isocycloseram via oxidases highlight cross‐resistance risks, emphasizing the need for routine ...

A genomic amplification affecting a carboxylesterase gene cluster confers organophosphate resistance in the mosquito Aedes aegypti: From genomic characterization to high‐throughput field detection

open access: yesEvolutionary Applications, 2021
By altering gene expression and creating paralogs, genomic amplifications represent a key component of short‐term adaptive processes. In insects, the use of insecticides can select gene amplifications causing an increased expression of detoxification ...

Effect of Organic Diet Intervention on Pesticide Exposures in Young Children Living in Low-Income Urban and Agricultural Communities. [PDF]

open access: yes, 2015
BackgroundRecent organic diet intervention studies suggest that diet is a significant source of pesticide exposure in young children. These studies have focused on children living in suburban communities.ObjectivesWe aimed to determine whether consuming ...
