Introgressed Brassica napus × Sinapis alba enhance resistance to the crucifer flea beetle (Phyllotreta cruciferae)

Pest Management Science, EarlyView.
This study demonstrates that Brassica napus lines with Sinapis alba introgressions enhanced resistance against Phyllotreta cruciferae, resulting in reduced feeding damage and improved seedling physiological performance. The introgressed lines showed strong potential as genetic resources for developing more resilient and sustainable canola varieties ...

2‐Amino‐3H‐phenoxazin‐3‐one is a lead inhibitor of Cuscuta campestris early development: structure–activity relationships of o‐aminophenol‐derived allelochemicals

Pest Management Science, EarlyView.
Phenoxazinones caused differential types of phytotoxic effects in C. campestris early development. APO is a coherent lead inhibiting C. campestris germination and early seedling growth. Abstract BACKGROUND 2‐Amino‐3H‐phenoxazin‐3‐one (synonym: questiomycin A; abbreviated as APO or Phx‐3) is a naturally occurring phenoxazinone‐type allelochemical with ...

Social Buffering of Pesticides in Bumblebees: Agent-Based Modeling of the Effects of Colony Size and Neonicotinoid Exposure on Behavior Within Nests

Frontiers in Ecology and Evolution, 2019
Neonicotinoids are a globally prevalent class of pesticides that can negatively affect bees and the pollination services they provide. While there is evidence suggesting that colony size may play an important role in mitigating neonicotinoid exposure in ...

The first report of M918L (super‐kdr) and L932F voltage‐gated sodium channel mutations in the English grain aphid (Sitobion avenae)

Pest Management Science, EarlyView.
The study has identified mutations in the voltage gated sodium channel of the English grain aphid (Sitobion avenae) at M918 and L932, which have not been previously reported in this species. Abstract BACKGROUND The grain aphid, Sitobion avenae Fabricius (Hemiptera: Aphididae), is a vector of yellow dwarf viruses and an important pest of cereals.

Nitenpyram seed treatment effectively controls against the mirid bug Apolygus lucorum in cotton seedlings

Scientific Reports, 2017
The mirid bug Apolygus lucorum (Meyer-Dür) has become a major pest in cotton fields and has led to significant yield losses due to the widespread use of transgenic Bt cotton in China.

Target‐site mutations and phenotypic failure in Myzus persicae against pyrethroids and carbamates in central Europe

Pest Management Science, EarlyView.
Molecular screening of 140 field‐collected Myzus persicae aphids revealed target‐site mutations L1014F, M918L, M918T, and L932F in the sodium channel and S431F in Ace2. The M918L mutation was the primary driver of high pyrethroid (cypermethrin) resistance, while S431F served as a definitive marker for carbamate (pirimicarb) resistance.

Interactions Between Thiamethoxam and Deformed Wing Virus Can Drastically Impair Flight Behavior of Honey Bees

Frontiers in Microbiology, 2020
Exposure to multiple stress factors is believed to contribute to honey bee colony decline. However, little is known about how co-exposure to stress factors can alter the survival and behavior of free-living honey bees in colony conditions.

Pesticide use in integrated pest and pollinator management framework to protect pollinator health

Pest Management Science, Volume 81, Issue 4, Page 1691-1696, April 2025.
Integrated pest management (IPM) emphasizes non‐chemical methods, with pesticides as a last resort, while integrated pest and pollinator management (IPPM) integrates pollinator health into pest control strategies. Abstract Agricultural pesticides have historically been a critical tool in controlling pests and diseases, preventing widespread suffering ...
