“…The increase in DHC particularly the immunocytes (Grs and Pls) have been reported by Shaurub and Sabbour (2017) with Melia azedarach (Meliaceae) fruit extract on Agrotis ipsilon Hufnagel (Lep: Noctuidae) and others (Sharma et al, 2008). The increase in DHC is somehow confusing, since the observation as live (Phase contrast) or permanent slides stained with Geimsa showing damaging cells but not degenerated after 24-48 h. Our results in damaged cells are corresponding to the reports of some other workers in their respective studies (Altuntas et al, 2012;Sadeghi et al, 2019).…”

“…Similarly, Rahimi et al (2013) and Khosravi et al (2014) also showed decreased number of cells in their respective insects upon IGRs treatment. On the effects of plant extracts or essential oils on THC, there are plenty of available literature (Sharma et al, 2003;Ghasemi et al, 2014;Shaurub et al, 2014;Dhivya et al, 2018;Sadeghi et al, 2019). The DHC in spite of increasing trend, the corresponding pictures, are clearly indicative of sever damages exerted by plant extract.…”

The effect of Withania somnifera a medicinal plant seed extract was tested against lesser mulberry pyralid, a potential pest of mulberry. The mulberry leaves were used for silk production in rural areas of northern Iran. The extract was administered orally by leaf dipping method in two lower (5%W/V) and higher (15%W/V) dosages to third instar larvae (<24 h) for biological assays and to fifth instar larvae (<24 h) for Physiological studies. The results showed formation of larvoids (Ls), larval-pupal intermediates (LPIs), pupoids (Ps) and pupal-adult intermediates (PAIs). The results showed increased larval duration by 1.7 and 2 folds in 5 and 15% treatment, respectively. Fecundity of resultant adults was decreased by 1.2 and 1.3 in 5 and 15% treatment, respectively. Except approximate digestibility (AD) and consumption index (CI) all other feeding indices showed reduction. The feeding deterrence was prominent at 15% (87%) and 5% showing 48% deterrence. Our enzymatic and non-enzymatic assessments upon treatment showed reduction in key components, except detoxifying enzymes. However, the activity of an important enzyme involved in cuticle hardening and immunity called phenoloxidase was reduced. We also investigated the histology of midgut for further analysis and found drastic changes in main cellular elements. Immunological changes following treatment was noticeable in reduced Total Hemocyte Count but surprisingly increased Differential Hemocyte Count. However, the hemocytes structure was extremely damaged. The reduced number of eggs in treated but survived adults indicated reduced ovaries, with vacuolization both in trophocytes and oocytes. The key chemical compounds showed reductions particularly at 15%. The present results are concomitant with few earlier studies on this medicinal plant and deserve further studies particularly in deriving key chemicals that alter metamorphosis similar to insect growth regulators.

“…Several studies support this finding whereby many plant products, essential oils, or growth regulators have been reported to influence the count of circulating hemocytes 7 , 62 – 65 . For example, essential oils isolated from four ecotypes of C. cyminum having cuminaldehyde, γ-terpinene, p-cymene, β-pinene, and α-phellandrene as main components, reduced the hemocyte count of pink stem borer, Sesamia cretica Lederer 66 . Botanicals are known to interfere with the normal hematopoiesis and lead to decreased cell division thereby reducing the number of circulating hemocytes.…”

“…On the other hand, a decrease in other hemocytes was observed. Many botanicals have been reported to cause alterations in the types of circulating hemocytes in the hemolymph of insect 13 , 66 – 70 . A review of previously reported literature reveals that dynamism in the proportions of hemocyte types i.e., change in the number of one hemocyte kind and simultaneous increase in the number of another hemocyte can be attributed to the acquirement of desirable immunological function (e.g., melanisation and/ phagocytosis).…”

Abstractγ-Terpinene, a monoterpene widely present in essential oils of many medicinal and aromatic plants with numerous biological properties, was evaluated for its insecticidal activity against melon fruit fly, Zeugodacus cucurbitae (Coquillett). Different concentrations (5, 25, 125, 625, and 3125 ppm) of γ-terpinene along with control were fed to larvae of melon fly. The number of pupae formed and adults emerged declined significantly after treatment. Morphologically deformed adults and pupae were also observed. The developmental duration too prolonged in treated larvae. Food assimilated, mean relative growth rate, larval weight gain, and pupal weight also declined. In the larvae treated with LC30 and LC50 concentrations, there was a decline in the titers of phenoloxidase and total hemocyte count, and variations were observed in the differential hemocyte count, suggesting an immunosuppressive effect of γ-terpinene on melon fly. Both concentrations also led to an increase in the apoptotic and necrotic cells as well as decrease in the viable hemocytes in the circulating hemolymph of treated larvae. Comet parameters (tail length, % tail DNA, tail moment, and olive tail moment) of γ-terpinene fed larvae increased significantly. Given the observed effects of γ-terpinene on normal developmental and nutritional physiology, its immunosuppressive properties, and its potential for genome damage, it can be considered for incorporation into integrated pest management strategies for controlling Z. cucurbitae.
