Short-term persistence of foliar insecticides and fungicides in pumpkin plants and their pollinators

PLoS ONE, Год журнала: 2025, Номер 20(4), С. e0311634 - e0311634

To minimize the risk to bees and other beneficial insects, plant protection chemicals are typically applied pollinator-dependent crop plants when flowers absent or unopened. However, this approach does not entirely remove of pollinator exposure. Much research has focused on negative effects systemic insecticides (e.g., seed treatments) pollinators, but less is known about level hazard posed by translocation non-systemic foliar-applied pesticides pollen nectar that consume. In study we assess frequency persistence six in pumpkin ( Cucurbita pepo ) tissues their bee visitors. We analyzed residues three (carbaryl, lambda-cyhalothrin, permethrin) fungicides (chlorothalonil, quinoxyfen, triflumizole) leaves, pollen, collected from five farms north-central USA, one day before a spray event, one, three, seven days after. Bees foraging were after screened for same pesticides. Overall, present 56% leaf samples. Compared fewer (insecticide detected 16%, fungicide 16%) samples (14%, 0%) contained insecticide (carbaryl) two out 69 bees, only male squash (not bumble honey bees), which have life history traits bring them into prolonged close contact with sprayed plants. The some agrochemicals up week following application merits consideration managing crops. Even traditionally considered contact-based unopened can reach produce measurable bees.

Availability of Using Honeybees and Hive Products as Bioindicators of Ambient Pesticide Exposure in Taiwan

Toxics, Год журнала: 2024, Номер 12(9), С. 639 - 639

Honeybees and hive products could be used as bioindicators of pesticide exposure in surrounding areas, but the associations have rarely been examined. We collected samples bees, environmental dust from 12 apiaries during blooming season eastern Taiwan assessed relationships between pesticides apiarian environment. Samples were analyzed for 14 using gas or liquid chromatography coupled with mass spectrometry. Sick dead bee pollen, beeswax outer rings (>150 m) contaminated high levels (mean concentration: >270 ng/g total). In terms concentrations all pesticides, insecticides, herbicides fungicides, most sample matrices significantly correlated within a range 2.5 km (ρ > 0.6, p < 0.05), suggesting their potential bioindicators. Of those contamination contents, bees may good bioindicator not herbicides, because insignificant correlation 0.5). For types we recommend sick pollen choices bioindicators, detection complete representativeness

Biology, Genetic Diversity, and Conservation of Wild Bees in Tree Fruit Orchards

Biology, Год журнала: 2022, Номер 12(1), С. 31 - 31

Опубликована: Дек. 24, 2022

Different species of bees provide essential ecosystem services by pollinating various agricultural crops, including tree fruits. Many fruits and nuts depend on insect pollination, primarily wild managed bees. In different geographical regions where orchard crops are grown, fruit growers rely in the farmscape use as alternative pollinators. Orchard such apples, pears, plums, apricots, etc., mass-flowering attract many bee during their bloom period. found orchards emerge from overwintering trees start flowering spring, active duration these aligns very closely with blooming time trees. addition, most short-range foragers tend to stay close crops. However, importance communities is not well understood, challenges maintaining populations remain. This comprehensive review paper summarizes types commonly fruit-growing United States, bio-ecology, genetic diversity. Additionally, recommendations for management bees, strategies protecting them multiple stressors, providing suitable on-farm nesting floral resource habitats propagation conservation discussed.

Higher early than late-season residue load of pesticides in honey bee bread in Slovakia

Apidologie, Год журнала: 2024, Номер 55(4)

Опубликована: Июнь 24, 2024

Abstract Bees are often exposed to pesticide residues during their foraging trips in agricultural landscapes. The analysis of in-hive stored pollen reflects the spectrum visited plants and can be almost used link exposure pesticides.In current study, bee bread samples were collected May July from 17 sites located southern Slovakia. Samples analysed using a multi-residue method for broad active substances microscopic identification.Our results revealed contamination with 19 different substances, fungicides being predominant. Sixteen them authorized EU, but chlorpyrifos, chlorpyrifos-methyl, chloridazon not. highest concentrations pendimethalin (1400 µg/kg), fluazifop-butyl (640 fenpropidin (520 fluopyram (130 difenoconazole (95 µg/kg) detected. total residue load sampled early season (May) was significantly higher than late (July). mean insecticides comprised 46% May’s load, which is alarming due importance diet winter-rearing bees. Moreover, both sampling periods showed that positively associated plant families Apiaceae Papaveraceae herbicides Aceraceae, Salicaceae, Brassica-type/Brassicaceae.Hence, considered suitable matrix good bio-indicator reflecting honey pesticides over season.
