Castor bean plant, Ricinus communis, containing the potent biopesticide ricinine, as an alternative host for mass rearing process of Tetranychus urticae and the most common phytoseiid predators

The medicinal plants have a vital role to take care of the healthy human life. The large family Euphorbiaceae contains nearly about 300 genera and 7,500 species. Amongst all, Ricinus communis L. or castor bean plant has high traditional and medicinal values towards a disease free community. The castor bean plant is effective as antifertility activity, antiimplantation activity, antinociceptive activity, anticancer activity, antioxidant activity, immunomodulatory activity, hepatoprotective activity, antidiabetic activity, antiulcer activity, antimicrobial activity, insecticidal activity, molluscicidal and larvicidal activity, bone regeneration activity, central analgesic activity, antihistaminic activity, antiasthmatic activity, cytotoxic activity, lipolytic activity, antiinflammatory activity, and wound healing activity. In addition, the constituents present in this plant are beneficial for the purpose of contraception, leaving no detrimental effects on the body. The objective of the present review focuses on the phytochemical constituents, pharmacological activities and future perspectives of the R. communis L. plant.

Mulches are known to conserve soil moisture, provide organic matter, protect soil and improve the soil as a growing environment. A field experiment was conducted to assess the effect of various mulch materials viz. dry oil palm bunch, saw dust and dry elephant grass at 25, 50 and 25 tons ha-1, respectively along with black plastic mulch on some soil physical and chemical properties and the performance of castor bean plant (Ricinus communis). All the mulches were applied to a mulch thickness of 5cm in this study. Results showed that pH values, organic carbon content and total nitrogen were all significantly improved by mulching. Bulk density values were reduced to 1.10 - 1.18gcm-3 across all treatments, when compared to the control at 1.33gcm-3. At 6 WAP, plastic mulching increased number of leaves from 16 to 40 leaves per plant and capsule weight from 63.1 to 161.3g/plant; when compared with the control.

Medicinal plants play a vital role in ensuring proper health is attained by human beings due to their antioxidants constituents. The large family Euphorbiaceae contain nearly about 300 genera and 7,500 species. Amongst all, Ricinus communis or castor bean plant has high traditional and medicinal values towards a disease-free community. The objective of this study focuses on the phytochemical constituents and phytotoxicity perspective of the R. communis plant. The castor bean plant is effective and is thought to have antifertility, anti-nociceptive, anticancer, antioxidant, immunomodulatory, hepato-protective, antidiabetic, antiulcer, antimicrobial bone regeneration, central analgesic, antihistamine, anti-asthmatic, cytotoxic, lipolytic, anti-inflammatory and wound healing potential. The seeds of R. communis were deshelled and manually separated from its shells. They were divided into three based on different methanol extraction (Fermented, Unfermented and Crystals of methanol extracts of unfermented). The quantitative phytochemical analysis showed variations in the phytochemical content of the unfermented and fermented methanol extracts respectively, alkaloids, flavonoids, tannins, soluble carbohydrates, hydrogen cyanides, steroids and phenols.

As an important pest, Tetranychus urticae fed on thousands of host plants and showed strong capability in host adaptation. However, hardly any success artificial diet has been developed for it. In this study, we compared adult longevity and reproduction of T. urticae that fed on its natural food (bean leaves) and an artificial diet with leaf extracts added, and tried to investigate the reason why the artificial diet was inefficient through transcriptome analyses. Mean adult longevity and cumulative fecundities of T. urticae was reduced by 53.4% and 93.8%, respectively. Transcriptome analyses showed that 1731 genes were differentially expressed comparing individuals fed with the artificial diet and with their natural food, among which most (77.1%) were down regulated. No significant induced expression of xenobiotic transporters and detoxification enzymes were observed when T. urticae were fed with the artificial diet. In contrast, differentially expressed genes were mainly enriched in digestive related terms, especially in lipid metabolism related pathways, with most genes down regulated. Our results indicated the significance in further investigating lipid demand and metabolism of T. urticae to improve its mass rearing techniques.
