LC50 values against these three species were 48.3, 62.8 and 54.7 mg/L for L. gibsoni essential oil and 118.5, 137.2 and 128.1 mg/L, respectively, for its acetone extract, while LC50 values for P. mollis essential oil were 25.4, 33.5 and 29.5 mg/L and 195.0, 213.8 and 209.0 mg/L, respectively, for its acetone extract. Repellence of the essential oils was assessed against A. aegypti adults. L. gibsoni essential oil provided 100 % protection for more than 7 h at a concentration of 2.0 mg/cm(2). Under the same conditions, the standard repellent N,N-diethyl-meta-toluamide, at 0.25 mg/cm(2), provided 100 % protection for more than 8 h, while P. mollis essential oil was only weakly repellent. The major components from both essential oils were identified based on GC-MS analysis and linear retention indices. Our results demonstrated promising larvicidal activities of both essential oils against these mosquito species. L. gibsoni essential oil also showed promising repellent activity.</p>10aEssential oil10aLavandula gibsoni10aMosquito larvicidal activity10aMosquito repellent10aPlectranthus mollis1 aKulkarni, Roshan, R.1 aPawar, Pushpa, V.1 aJoseph, Mary, P.1 aAkulwad, Ambadas, K.1 aSen, Avalokiteswar1 aJoshi, Swati, P.  uhttps://library.ncl.res.in/content/lavandula-gibsoni-and-plectranthus-mollis-essential-oils-chemical-analysis-and-insect-002074nas a2200181   4500008004100000245017100041210006900212260000800281300001000289490000700299520135000306100001801656700002301674700002001697700002301717700002901740856012301769       2016                        eng d00aParasitism by Chelonus blackburni (Hymenoptera) affects food consumption and development of Helicoverpa armigera (Lepidoptera) and cellular architecture of the midgut0 aParasitism by Chelonus blackburni Hymenoptera affects food consu  cMAR  a65-700 v193 aBiological control agents are vital components of an integrated pest management strategy, and this is frequently referred to as natural control. Natural enemies of insect pests include predators, parasitoids, and pathogens. Among them, a parasitoid, Chelonus blackburni (Cameron), was found to be the best biological control agent for the polyphagous pest, Helicoverpa armigera (Hubner). C. blackburni alters the feeding performance of H. annigera larvae upon parasitism and as a result severely affects growth and development. Moreover, it shortens the feeding period of H. armigera and increases mortality. Furthermore, total hemocyte count (THC) was significantly decreased in parasitized larvae than control. Parasitized H. armigera had 26% less number of blood cells compared to healthy larvae. Histological studies showed that the structure of midgut of H. annigera is drastically affected by C. blackburni leading to reduced food consumption, which ultimately led to larval death. The present study provides an insight to changes involved in H. annigera due to parasitism by C blackburni, a parasite that could be used as an effective biocontrol agent to manage H. armigera.

However, the Xanthopimpla pedator (F.) (Hymenoptera: Ichneumonidae) is a major pupal endoparasitoid of A. mylitta, which affects the total tasar silk production in India. A gravid female X. pedator parasitizes the pupae of A. mylitta by depositing an egg, which produces a single offspring per host. We studied the development of immature forms of X. pedator by dissecting parasitized pupae of A. mylitta under laboratory conditions at 28-30 degrees C and 40-60% relative humidity. All immature stages of the parasitoid develop within the host in 20-22 d, by devouring the entire pupal content, resulting in dead or seedless cocoons. The total life cycle of X. pedator is completed inside the host pupa and the adult emerges out by rupturing the peduncle end of the cocoon. During development of X. pedator, five preimaginal stages, viz., egg, larval instars, prepupa, pupa, and a pharate adult, were observed. Xanthopimpla pedator passes through five larval instars identified by structural and morphometric variations. These include primary larva (L1), the intermediate larvae (L2-L4), and the finalinstar larva (L5). Biometric study and larval head width permitted the morphological separation of all five larval instars. In the present study, the biology and development of X. pedator inside the pupa of A. mylitta are reported for the first time with detailed photomicrographs. Therefore, the study may enable the information concerning physiological interactions between A. mylitta and its endoparasitoid, X. pedator.1 aGathalkar, Ganesh, B.1 aBarsagade, Deepak, D.1 aSen, Avalokiteswar  uhttps://library.ncl.res.in/content/biology-and-development-xanthopimpla-pedator-hymenoptera-ichneumonidae-pupal-endoparasitoid01750nas a2200229   4500008004100000245008100041210006900122260000800191300001600199490000600215520098800221100002501209700001801234700001701252700002501269700002601294700003001320700001801350700002301368700002101391856010801412       2021                        eng d00aIdentification of a novel series of potent organosilicon mosquito repellents0 aIdentification of a novel series of potent organosilicon mosquit  cNOV  a31236-312430 v63 aMosquito control by personal protection is one of the most efficient ways of curtailing deadly diseases such as malaria and dengue with the potential to save millions of lives per year. DEET (N,N-diethyl-3-methyl benzamide) is currently considered as the gold standard for mosquito repellents, being used for the past several decades. Control by DEET, however, is being threatened by emerging resistance among mosquitoes. To address this concern and also to improve protection times, we synthesized a novel series of 25 silicon-containing acyl piperidines using acid–amine coupling protocol and tested their activity against Aedes aegypti in mosquito-repellent assays. Several compounds from this series appear to possess good mosquito-repellent properties. Most notably, at 0.5 mg/cm2 concentrations, the mean protection time for NDS100100 was 756 min, which was higher than that of DEET (616 min). The details of design, synthesis, and biological evaluation are discussed herein.1 aKulkarni, Akshay, S.1 aRamesh, Remya1 aWalia, Safal1 aSayyad, Shahebaz, I.1 aGathalkar, Ganesh, B.1 aBalamkundu, Seetharamsing1 aJoshi, Manali1 aSen, Avalokiteswar1 aReddy, Srinivasa  uhttps://library.ncl.res.in/content/identification-novel-series-potent-organosilicon-mosquito-repellents
