“…Pyrethroids are also commonly used in crop protection against various insects considered as pests . According to related reports, single‐crop pollination requires 1.6 million bee colonies to provide services, while pyrethroids are used in nearly 1 million acres of orchard (including apples, apricots, sweet and tart cherries, peaches, plums, prunes, pears, and nectarines) in the USA . Cypermethrin and deltamethrin are the two most common pyrethroid insecticides .…”

Background The effects of exposing Apis mellifera larvae to common insecticides were tested in the laboratory. Results The acute toxicity values of the four insecticides that we tested ranged from high toxicity to low toxicity: deltamethrin > cypermethrin > carbaryl > acetamiprid. The NOAEC (no observed adverse effect concentration) values of the chronic toxicity tests for each compound are 5 mg L−1 for acetamiprid, 2 mg L−1 for carbaryl, 1 mg L−1 for cypermethrin, and 0.2 mg L−1 for deltamethrin. Conclusion According to the risk quotient (RQ) values of acute and chronic toxicity that we obtained, the risk is acceptable at exposure rates that have been identified in the field. Overall, our results are valuable for evaluating the acute and chronic toxicities of these insecticides to developing honey bees. © 2019 Society of Chemical Industry

“…Secondary effects can cause damage to adult bees, such as disorientation, which could compromise their return to the colony (Ingram et al, 2015;Silva et al, 2016). Furthermore, bees could transport the chemical products to colonies, accumulating pesticides in the food, which suggests poisoning the larvae when fed with these contaminated products (Johnson et al, 2010;Martinello et al, 2017).…”

Toxicity of Fenpyroximate, Difenoconazole and Mineral Oil on Apis mellifera L. Introduction

Bees of genus Apis are the main crop pollinators; however, the use of pesticides in agriculture may intoxicate them during foraging. In this study, we evaluated the toxic eff ects caused by difenoconazole (fungicide), fenpyroximate (acaricide) and mineral oil (adjuvant) used alone and associated (pesticide + adjuvant) on workers of Apis mellifera L. Bees were exposed to product doses recommended by manufacturers, orally and in contact on a contaminated surface in a controlled environment. All products presented low lethality, both in isolation and combination (except for difenoconazole via contact), however, they all showed toxic effects. The results showed that combination of pesticides with adjuvant augmented toxic eff ects.

“…Numerous convergent observations show that chemical control has important effects on pollinating insects, which suffer immediate or delayed losses that affect adults or larvae (Carvalheiro et al, 2013)). Pyrethroids have been reported to pose repellency which alters foraging behavior with the benefit of preventing bees from encountering a lethal dose in the field (Ingram et al, 2015). However, sub-lethal exposure to pyrethroids may adversely impact bee behavior potentially resulting in social dysfunction or disruption of foraging (Ingram et al, 2015).…”

Agrochemicals are considered to be among the major environmental threats to pollinators, including honey bees. At the time of foraging, bees are at risk of exposure to phytosanitary treatment as a result of widespread treatment and their location, often near orchards. In Algeria, the majority of farmers systematically over-treat their orchards in order to have good quality fruits for as long as possible towards the use of an effective product. We evaluated the comparative effects of lambda-cyhalothrin and spinosad insecticide treatments on bees in tomato plots. Fluctuations of bee populations abundance were established during a 16 days period of exposure using yellow-colored plates with water placed every two days inside the experimental units. Bee populations showed very high sensitivity (0 individuals registered) to both insecticides at the homologated dose and even half dose during 10 days following application of the treatments. Depending on the estimated temporal toxicity of the respective products, differences in recovery of bee activity are presented. Consideration of indicators of the intensity of use of plant protection products is discussed.
