“…If the JH is present during these sensitive periods, the current developmental state or status quo will be maintained (Nijhout, 1998) and the switch to next developmental stage will not take place (Riddiford, Hiruma, Zhou, & Nelson, 2003). This clearly demonstrates that the plant extracts from the medicinal plant, Ashwagandha, W. somnifera mimic the action of JH producing similar effects as with the exogenous administration of JHAs as the presence of JHAs during sensitive/critical period may lead to inhibition of ecdysone production or alteration of ecdysteroid titer in the insect body (Alizadeh et al, 2012;Ghasemi, Sendi, & Ghadamyari, 2010;Suzuki, Sakurai, & Iwami, 2010).…”

“…Such type of prolongation of developmental period was similar to that produced by the administration of juvenile hormone analogue (JHA), pyriproxyfen, to different larval instars of lepidopteran insects viz. fifth instar larvae of Choristoneura rosaceana (Lepidoptera: Tortricidae) (Sial & Brunner, 2010), second instar larvae of S. littoralis (Nasr, Badawy, & Rabea, 2010), and third instar larvae of Plutella xylostella (Lepidoptera: Plutellidae) (Alizadeh et al, 2012). In addition to that, administration of botanical extracts/natural products causing prolongation of developmental stages in other insects have also been described such as seed extracts of A. indica and leaves extracts of Citrullus colocynthis in Schistocerca gregaria (Orthoptera: Acrididae) (Nassar, Ghazawy, Torkey, & Rawy, 2018); rotenone from the roots of Lanochocrapus species or Derris species and limonine from citrus fruit peels in the vector of Bancroftian filariasis, Culex (Cx.)…”

A comparative bioefficacy of seed and root extracts of a medicinal plant, Withania somnifera when administered to prepupae of lepidopteran insects, Spodoptera litura (Lepidoptera: Noctuidae) and Pericallia ricini (Lepidoptera: Arctiidae)

Background: The lepidopterans, Spodoptera litura and Pericallia ricini, are polyphagous pests of agricultural importance. The unscrupulous and non-judicious use of chemical pesticides for controlling the insect pests has resulted into severe environmental hazards, threatening non-target organisms and human health. Results: Administration of seed and root extracts of a medicinal plant, Ashwagandha (Withania somnifera) to prepupae of two economically important insect pests viz. S. litura and P. ricini resulted into disruption of molting and metamorphosis leading to a number of developmental aberrations such as prolongation of the life span of prepupae, postponement of pupal-adult ecdysis, ecdysial failure, reduced pupation and adult emergence, formation of larval-pupal and pupal-adult intermediates, abnormal pupae, and adultoids. Treatment with seed extracts of W. somnifera was more effective as it alone caused mortality in both the lepidopteran insects viz. S. litura and P. ricini, whereas no such effect was observed when treated with root extracts. P. ricini was more susceptible to W. somnifera as it resulted into formation of larval-pupal-adult chimeras in addition to effects described earlier, whereas this effect was not observed in the case of S. litura. Conclusion: These results are similar to these produced by the administration of JHAs and hence mimic their action by the way of interfering with the neuroendocrine system.

“…The overuse of chemical pesticides against this pest has resulted in resistance to all groups of insecticides, including insect-growth regulators (Alizadeh et al 2012) and Bacillus thuringiensis Berliner (Karimzadeh & Sayyed 2011;Gulzar et al 2012). In addition, the intensive use of insecticides has eliminated effective natural predation of P. xylostella in field.…”

The recent major outbreaks of diamondback moth, Plutella xylostella (Lepidoptera: Plutellidae), in cruciferous plants in Iran has led to attempts for sustainable pest management strategies, mainly based on the natural enemies. The present study aimed to investigate naturally occurring parasitism of P. xylostella in cabbage and cauliflower fields of central Iran. For this purpose, field studies were performed to identify parasitoids of P. xylostella, and to evaluate percentage parasitism of P. xylostella using the recruitment method in main cabbage-growing areas of Isfahan province in 2009. In present study, seven species of parasitoid wasps (five larval and two pupal parasitoids) and two species of hyperparasitoid wasps were determined. The parasitoids included the braconids Cotesia vestalis (Kurdjumov), Bracon hebetor Say and Apanteles sp., the ichneumonid Diadegma semiclausum (Hellen), and the eulophid Oomyzus sokolowskii (Kurdjumov) as larval parasitoids, and the ichneumonids Diadromus collaris (Gravenhorst) and Diadromus subtilicornis (Gravenhorst) as pupal parasitoids. In addition, the pteromalids Mokrzeckia obscura Graham and Pteromalus sp. were identified as the hyperparasitoids, which in turn parasitise C. vestalis. The most predominant species were C. vestalis and D. semiclausum with the proportional abundance of 0.43 and 0.42, respectively. Percentage parasitism varied significantly between host plants, but not between areas; the parasitised proportion of P. xylostella larvae fed on common cabbage was significantly greater than that on cauliflower (0.42 vs. 0.34). The mean percentage parasitism varied between 14.5 and 68.4 for different fields, and accounted for 37.4% of P. xylostella population on an average. The greatest parasitism was achieved by C. vestalis, D. semiclausum and O. sokolowskii, with a parasitism of 21.0, 12.9 and 3.5% of field populations of P. xylostella, respectively. These findings illustrated the important role of parasitoids for sustainable management of diamondback moth.
