“…Development should be affected more by insect growth regulators than by neurotoxic pesticides. However, application of buprofezin did not cause ontogenetic disruption in the two lycosids P. piratoides 90 and P. pseudoannulata 37. But the application of azadirachtin had similar effects to those reported for pesticides:97, 98 reduced growth and the occurrence of deformations in the ontogenetic development of the lycosid Schizocosa humilis (Banks, 1892) 61.…”

Being one of the most abundant and species-rich groups of natural enemies occurring in all agroecosystems, spiders are variably affected by pesticide applications. Here, a review is given of research on spider ecotoxicology. More than 40 species of spiders and almost 130 pesticides (acaricides, insecticides, fungicides and herbicides) have been tested so far in the field or under laboratory conditions. Field studies show that the degree of population reduction following pesticide application is a function of a number of factors inherent to pesticides, crops and spider species (guilds). These studies also revealed indirect effects via habitat and prey disruption. Among laboratory studies, a number of papers have investigated only the direct lethal effect. A meta-analysis of these data reveals that spiders are mainly affected by acaricides and insecticides, particularly neurotoxic substances. Currently, ecotoxicological research on spiders is focused more on direct sublethal effects on a variety of behavioural traits (locomotion, predation, web-building, reproduction, development) and physiology. Yet a standardised approach to the evaluation of sublethal effects is lacking. A few studies have provided some evidence for hormesis in spiders. Future research should be more concentrated on sublethal effects and the estimation of long-term changes in spider populations as a result of pesticide treatment.

“…Valle et al (2002) recorded that buprofezin prevents the adult emergence from the pseudopupa of B. tabaci. Deng et al (2008) found that buprofezin significantly reduced the percentage hatching of spiders' eggs but had only a slight effect on the egg production. Hoffmann et al (2009) found that thiamethoxam reduced larval emergence rates by > 90% for all life stage targets in Plum curculio.…”

“…The authors found that lambda-cyhalothrin was highly effective in dryland Bacillus thuringiensis cotton compared with spinosad and thiodicarb. Deng et al (2008) stated that buprofezin had low toxicity to the wolf spider, Pirata piratoides. Gough and Wilkinson (1984) found that buprofezin was not effective against the cotton bollworm, Helicoverpa armigera, at any tested dose for any time of treatment in any spray.…”

Laboratory bioassay showed that the conventional pesticide, lambda-cyhalothrin, was more effective than thiamethoxam and buprofezin when tested against the newly hatched larvae of the pink bollworm, Pectinophora gossypiella (Saunders). The LC 50 of thiamethoxam, buprofezin and lambda-cyhalothrin was 5.9, 87.5 and 4.9 ppm, respectively. When the synergism agent, piperonyl butoxide (PBO), was combined with the tested pesticides, the toxicity of all pesticides was increased and the LC 50 was decreased to 1.4, 15.1 and 2.6, respectively. Some biological aspects (larval duration, pupal stage, number of eggs laid per female and percent of hatchability) were affected by buprofezin treatment more than thiamethoxam and lambda-cyhalothrin. A field experiment showed that lambda-cyhalothrin was the most effective when compared to thiamethoxam and buprofezin. The percentage of reduction in pink bollworm infestation to cotton bolls by using lambda-cyhalothrin, thiamethoxam and buprofezin was 85.7, 39.3 and 19.5%, respectively, during 2009 cotton season, and 80.1, 64.7 and 39.1%, respectively, during 2010 cotton season. These results suggested that lambda-cyhalothrin is the most effective pesticide against the pink bollworm larvae. And also, buprofezin has a good role in incidence of disturbance in developmental process. In addition, the use of synergistic agent PBO has a good role in increasing toxicity of all the tested pesticides especially with thiamethoxam.

“…Due to its widespread use, buprofezin residue has been frequently detected in food, soil, and drinking water (7)(8)(9)(10). Toxicity studies have shown that buprofezin is toxic to some aquatic organisms and nontarget insects (11)(12)(13)(14)(15). Buprofezin is considered to have low acute toxicity to humans and other mammals (acute rat oral 50% lethal dose [LD 50 ] is 1,635 mg · kg Ϫ1 in males).…”

Buprofezin is a widely used insect growth regulator whose residue has been frequently detected in the environment, posing a threat to aquatic organisms and nontarget insects. Microorganisms play an important role in the degradation of buprofezin in the natural environment. However, the relevant catabolic pathway has not been fully characterized, and the molecular mechanism of catabolism is still completely unknown. Rhodococcus qingshengii YL-1 can utilize buprofezin as a sole source of carbon and energy for growth. In this study, the upstream catabolic pathway in strain YL-1 was identified using tandem mass spectrometry. Buprofezin is composed of a benzene ring and a heterocyclic ring. The degradation is initiated by the dihydroxylation of the benzene ring and continues via dehydrogenation, aromatic ring cleavage, breaking of an amide bond, and the release of the heterocyclic ring 2-tert-butylimino-3-isopropyl-1,3,5-thiadiazinan-4-one (2-BI). A buprofezin degradation-deficient mutant strain YL-0 was isolated. A comparative genomic analysis combined with gene deletion and complementation experiments revealed that the gene cluster bfzBA3A4A1A2C is responsible for the upstream catabolic pathway of buprofezin. The bfzA3A4A1A2 cluster encodes a novel Rieske nonheme iron oxygenase (RHO) system that is responsible for the dihydroxylation of buprofezin at the benzene ring; bfzB is involved in dehydrogenation, and bfzC is in charge of benzene ring cleavage. Furthermore, the products of bfzBA3A4A1A2C can also catalyze dihydroxylation, dehydrogenation, and aromatic ring cleavage of biphenyl, flavanone, flavone, and bifenthrin. In addition, a transcriptional study revealed that bfzBA3A4A1A2C is organized in one transcriptional unit that is constitutively expressed in strain YL-1. IMPORTANCEThere is an increasing concern about the residue and environmental fate of buprofezin. Microbial metabolism is an important mechanism responsible for the buprofezin degradation in the natural environment. However, the molecular mechanism and genetic determinants of microbial degradation of buprofezin have not been well identified. This work revealed that gene cluster bfzBA3A4A1A2C is responsible for the upstream catabolic pathway of buprofezin in Rhodococcus qingshengii YL-1. The products of bfzBA3A4A1A2C could also degrade bifenthrin, a widely used pyrethroid insecticide. These findings enhance our understanding of the microbial degradation mechanism of buprofezin and benefit the application of strain YL-1 and bfzBA3A4A1A2C in the bioremediation of buprofezin contamination.
