Abstract: The effect of 2-tridecanone vapor on the cowpea weevil (Callosobruchus maculatus) development was determined. Seeds of cowpea were infested with adults and exposed to different doses of 2-tridecanone isolated from Pilocarpus microphyllus Stapf ex Holm, a plant species native from northeastern Brazil. The pure monoterpene was evaluated both undiluted as well as in the dilutions 1:10, 1:100 and 1:1,000 (v/v). The following parameters of the cowpea weevil life cycle were analyzed in response to decreasing doses o… Show more

“…However, in the present study when fractionated latex samples were used, its toxicity remained intact with the fractions and showed higher insecticidal activity in Odontotermes obesus. It is due to presence of soluble components in C. procera latexes, but precipitated substance did not show any deterrent effect on insects [68,69]. Thus, deterrent activity may be a consequence of a repellent effect, which is certainly operated by some soluble and non-volatile substances from latexes.…”

“…Thus, proteins, enzymes and allergens protect plants from herbivorous insect attack [64,65], but it is still unclear that repellent activity in plant latexes is due to presence of proteins or volatile substances occur in latex fluid [66]. As literature reveals, plant latexes contain different chemical components which show high anti-feedant, effects on herbivorous insects, when treated with different doses [67] in artificial diets [68]. These candidate molecules which exhibit repellency are monoterpenes, alkaloids, phenolic glycosides, [6] and 2-tridecanone [67].…”

“…[161] Besides poisoning of insects, C. procera latex also show high antifeedant activity at low doses. [162] It signifies presence of some distasteful components such as monoterpenes, phenolic glycosides, [163] 2-tridecanone, [162] alkaloids, resins, tannins, saponins, enzymatic proteins and allergens in natural latex that show diverse biological activities. [164] These components make the food distasteful/unpalatable or highly allergic to insects [165] that deter crop pests from feeding on plants.…”

“…In previous reports, 2‐tridecanone exhibited insecticidal and acaricidal activity against several insects and mites, e.g. tomato fruitworm ( Heliothis zea ), tomato pinworm ( Keiferia lycopersicella ) and beet armyworm ( Spodoptera exigua ), two‐spotted spider mite ( Tetranychus urticae ), green peach aphid ( Myzus persicae ), tobacco hornworm ( Manduca sexta ) and tobacco budworm ( H. virescens ) and cowpea weevil ( Callosobruchus maculatus ) . Moreover, 2‐undecanone is famous for its repellency .…”
