Fungicides affect Japanese beetle Popillia japonica (Coleoptera: Scarabaeidae) egg hatch, larval survival and detoxification enzymes

Abstract

Fungicide applications to turfgrass that coincide with oviposition and egg hatch of white grubs may have sublethal effects. This work is applicable both to high-maintenance turfgrass such as golf courses, where applications of pesticides are more frequent, and to home lawn services, where mixtures of multiple pesticides are commonly used.

Imidacloprid seed treatments affect individual ant behavior and community structure but not egg predation, pest abundance or soybean yield

“…The fungicide itself used on seed treatments had lethal effects and sublethal influences on ant movements, indicating potentially strong non‐target effects on ant communities. Fungicides have been reported to cause death and altered foraging/nesting behaviors in other insects, but have not been well studied on ants, especially when used in conjunction with insecticides . As the foraging time and success rates were not impacted in either the laboratory or field assays, these sublethal effects from imidacloprid and fungicides might impact ant colonies in other ways such as their ability to reproduce or the longevity and aggression of a colony .…”

Toxicity and risk assessment of nine pesticides on nontarget natural predator Harmonia axyridis (Coleoptera: Coccinellidae)

“…1,2 Some fungicides are used in greenhouses to protect plants, which also leads to the exposure risk of predatory organisms. 3,4 Moreover, pesticide-sprayed fields were observed to negatively affect nontarget arthropods (NTAs) in an off-field scenario by drift. 5,6 Assessing the potential risk of pesticides to nontarget predators will contribute to the protection of the important ecological functions of predators.…”

Adult Popillia japonica as an Otorhinolaryngologic Invasive Foreign Body in a Rural Area

“…A green head and body recognize them with copper, brown-coloured wings, approximately 10mm in length [4]. Studies on the Japanese beetle are primarily focused on containment and eradication strategies to decrease spread and damage to crops [5,6]. Limited research exists on medical complications related to the Japanese beetle as it is not known to harm humans or livestock directly.…”
