The residue of imidacloprid in the nectar and pollens plants is toxic not only to adult honeybees but also larvae. Our understanding risk larvae still a very early stage. In this study, capped-brood, pupation eclosion rates honeybee were recorded after treating them directly hive with different dosages imidacloprid. brood-capped decreased significantly when increased from 24 8000 ng/larva. However, there no significant effects DMSO or 0.4 ng per larva on brood-capped, rates. Although...
While the natural foods of western honey bee (Apis mellifera) contain diverse phytochemicals, in contemporary agroecosystems bees also encounter pesticides as floral tissue contaminants. Whereas some ubiquitous phytochemicals up-regulate detoxification and immunity genes, thereby benefiting nestmates, many agrochemical adversely affect health even at sublethal levels. How assess xenobiotic risk to nestmates they forage is poorly understood. Accordingly, we tested nine nectar, pollen, or...
Because certain flavonols and phenolic acids are found in pollen nectar of most angiosperms, they routinely ingested by Apis mellifera, the western honey bee. The flavonol quercetin acid p-coumaric known to upregulate detoxification enzymes adult bees; their presence or absence diet may thus affect toxicity pesticides. We conducted a series longevity assays with one-day-old workers test if dietary phytochemicals enhance pesticide tolerance. One-day-old bees were maintained on sugar syrup...
For the past decade, migratory beekeepers who provide honey bees for pollination services have experienced substantial colony losses on a recurring basis that been attributed in part to exposure insecticides, fungicides, or their combinations applied crops. The phytochemicals p -coumaric acid and quercetin, which occur naturally wide variety of bee foods, including beebread many types honey, can enhance adult longevity reduce toxicity certain pesticides. How variation concentrations natural...
The parsnip webworm, Depressaria pastinacella, is restricted to two hostplant genera containing six structurally diverse furanocoumarins. Of these, imperatorin detoxified by a specialized cytochrome P450, CYP6AB3. A previous whole-larva transcriptome analysis confirmed the presence of nine transcripts that belong CYP6AE subfamily. Here, examining midgut-specific gene expression patterns we determined CYP6AE89 were highly expressed and furanocoumarin-inducible. Computer docking...
As a managed agricultural pollinator, the western honeybee Apis mellifera frequently encounters agrochemicals as contaminants of nectar and pollen. One such contaminant, fungicide boscalid, is applied at bloom in orchards for fungal floral pathogen control. an inhibitor complex II mitochondrial electron transport chain fungi, boscalid can potentially interfere with high energy-demanding activities bees, including flight. We designed indoor flight treadmill to evaluate impacts ingesting...
It is well known that the honeybee has good color vision. However, spectral range in which bee can see different from of human eye. To study how bees view their world colors, one to through eyes bee, not a human. A conventional way examine signals animals detect measure surface reflectance spectra and compute quantum catches each photoreceptor type based on its sensitivity. Color signal contrast are then determined loci these space. While point-by-point measurements using standard...
Abstract. Adult flea beetles, Phyllotreta striolata , show a strong positive phototactic response. The action spectrum of phototaxis dark‐adapted beetles was measured with minimal required light intensity between the wavelength range 300 nm and 600 nm. Male female showed identical phototacitc behaviours. were most sensitive to peak wavelengths 350 430 in morning. In afternoon evening, sensitivity shorter than decreased, but they remained These results suggest that changes photoreceptors or...
Firefly luminescence is an intriguing phenomenon with potential technological applications, whose biochemistry background was only recently established. The physics side of this phenomenon, however, still unclear, specifically as far the oxygen supply mechanism for light flashing concerned. This uncertainty due to complex microscopic structure tracheal system: without fully knowing its geometry, one cannot reliably test proposed mechanisms. We solved problem using synchrotron phase contrast...
Abstract Exposure to agrochemical sprays containing pesticides and tank-mix adjuvants has been implicated in post-bloom mortality, particularly of brood, honey bee colonies brought into California almond orchards for pollination. Although are generally considered be biologically inert, some have exhibited toxicity sublethal effects, including decreasing survival rates next-generation queens. Honey bees a highly developed olfactory system detect discriminate among social signals. To...
Insecticide toxicity to insect herbivores has long been known vary across different host plants; this phenomenon widely documented in both foliage-feeders and sap-feeders. Species-specific phytochemical content of hostplant tissues is assumed determine the pattern induction enzymes that detoxify insecticides, but specific phytochemicals have rarely linked plant-associated variation pesticide toxicity. Moreover, no studies date examined effects nectar source identity composition on...
Inspection plays an important role in the semiconductor industry. In this paper, we focus on inspection task after wire bonding packaging. The purpose of (W/B) is to connect bond pads with lead fingers. Two major types defects are (1) line missing and (2) breakage. numbers lines balls used as features for defect classification. proposed method consists image preprocessing, orientation determination, connection detection, ball simple fast. experimental results show that can detect effectively.
