Effect of the extract and compound from Solanum nigrum Linn on Tetranychus cinnabarinus

Abstract

The carmine spider mite Tetranychus cinnabarinus (Boisduval) is a serious pest affecting various glasshouse vegetables, fruits and crops and causes significant damage to crop yields and quality by piercing and sucking foliar tissues. The control of this mite primarily involves the application of synthetic chemical pesticides. In this study, a Solanum nigrum L. extract was evaluated for its potential acaricidal activity against adult female T. cinnabarinus in laboratory conditions, and the S. nigrum extract showed marked efficacy in controlling the carmine spider mite both in vitro and in potted seedlings. Furthermore, the active compound, a phytostanol ester (β‐sitosterol‐3‐O‐heptadeca‐8Z, 11Z‐dienoate), was isolated from the petroleum ether‐soluble fraction of S. nigrum extract via repeated column chromatography and identified based on its physiochemical properties and spectral data. At 7 days after treatment in a potted seedling experiment, the LC50 values of the S. nigrum extract and active compound were found to be 4.70 and 1.85 g/l, respectively. All of these results demonstrated that the S. nigrum extract and its active component exhibit the potential for use as new natural acaricides for controlling carmine spider mites.

Effect of acaricidal compound extracted from Arachis hypogaea Linn against Tetranychus cinnabarinus

“…Furthermore, an insecticidal constituent isolated from Thymus mongolicus identified as β‐sitosterol was found to show an LC 50 value of 1,522 mg/L in a slide‐dip bioassay, which was higher than the LC 50 value of palmitic acid of 534.58 mg/L (Li et al, ). In addition, according to Chen and Dai (), the active compound b‐sitosterol‐3‐O‐heptadeca‐8Z,11Z‐dienoate obtained from a S. nigrum extract consistently exhibits good acaricidal activity against T. cinnabarinus and the LC 50 value of the compound was calculated to be 640 mg/L after 24 hr in leaf‐dip assays, which was also higher than the LC 50 value of palmitic acid determined in the same way. As mentioned above, palmitic acid shows significant acaricidal activity compared with many other active compounds from natural plants .…”

“…Recently, extracts of various plants have been shown to possess acaricidal activities against T. cinnabarinus , such as those of Mentha piperita (Ren et al, ), Curcuma longa L. (Liu et al, ), Inula britanica (Ma et al, ), Chenopodium quinoa Willd (Harder, Tello, & Giliomee, ), Solanum nigrum Linn (Chen & Dai, ), Aloe vera L. (Zhang, Zhang, Luo, & Ding, ), Lactuca sativa (Li et al, ) and Polygonum aviculare (Cheng, Wang, Ma, Liu, & Shi, ) . These acaricidal plants influence the growth and development of T. cinnabarinus through repellence, antifeeding effects or oviposition deterrence (Chen & Dai, ).…”

Metabolite Content of Local Bitter White Lupin Seeds (Lupinus albus L.) and Acaricidal and Insecticidal Effects of its Seed Extract

“…Even though there are several studies on T. urticae regarding plant-based compounds prepared using different plants, no study carried out using Lupine seed extract has been observed in the literature. In studies regarding acaricidal effect of extracts made from different plants on T. urticae, it was observed that the resulting effect varied depending on the plant species, extract concentration and application period (Tunc & Sahinkaya 1998;Topakcı et al 2005;Sertkaya et al 2010;Topuz & Madanlar, 2011;Chen & Dai 2017).…”

Semisynthesis of novel N‐acyl/sulfonyl derivatives of 5(3,5)‐(di)halogenocytisines/cytisine and their pesticidal activities against Mythimna separata Walker, Tetranychus cinnabarinus Boisduval, and Sitobion avenae Fabricius

“…With the drive toward increasing food production and efficiency, steps should be taken to reduce increasing insect pest threats to crop production . Mythimna separata Walker (Oriental armyworm), Tetranychus cinnabarinus Boisduval (spider mite) and Sitobion avenae Fabricius are three threatening and typical insect pests of a wide range of crops, and their infestations are usually very serious and hard to control . In China, intermittent outbreaks of M. separata occurred widely in 2012, and approximately four million hectares of crops were completely lost .…”

[2][3][4] In China, intermittent outbreaks of M. separata occurred widely in 2012, and approximately four million hectares of crops were completely lost. 5 Meanwhile, due to the extensive and unreasonable application of synthetic pesticides to control pests, resistance in pest populations and negative impacts on human health and environmental safety have simultaneously emerged.…”
