In this study, Angelica dahurica and Angelica pubescentis root essential oils were investigated as pest management perspectives, and root samples were also analyzed genetically using the nuclear ribosomal internal transcribed spacer (ITS) region as a DNA barcode marker. A. pubescentis root essential oil demonstrated weak antifungal activity against Colletotrichum acutatum, Colletotrichum fragar...

pathogenic infection in tasar silkworm, antheraea mylitta drury. is common and there is a breed specific response regarding tolerance. observations reveal the possibility of differential response by haemocytes to microbial infection in different breeds. hence, the susceptibility of three eco-races of tasar silkworm viz. daba, sarihan and raily to antheraea mylitta cytoplasmic polyhedrosis virus...

Alburnus mossulensis has been exposed to lead and cadmium for (96)h in order determination lethal concentration 50 (LC50) value. A total of 140 fish used this experiment divided into two groups each group contain 70 fishes .The first exposure pbcl2 while the second cdcl2. Method Finney Probit Analysis analysis data. LC50 value PbCl2 CdCl2 was (57.8 29.6) mg/l respectively. Then about 200 4 grou...

Fasciolosis is a parasitic disease caused by Fasciola gigantica. The freshwater snail Lymnaea acuminata is the intermediate host of F. gigantica which cause endemic fasciolosis in the northern part of India. To investigate larvicidal activity of pure and laboratory extracted pheophorbide a (Pa) against cercaria larvae of F. gigantica, data were analyzed in different spectra of visible light, su...

Plants are the important source of diverse range of bioactive principles. A large number of plants are constantly being screened for their possible medicinal value. The present study was designed to investigate the antimicrobial and cytotoxic activity of ethyl acetate (EAE), chloroform (CE) and n-hexane (HE) extracts of leaves of Cucumis sativus. Antimicrobial activity of EAE, CE and HE was tes...

Laboratory bioassays using leaf disks of apple dipped in test solutions of insecticides demonstrated that the apple aphid, Aphis pomi De Geer, and the spirea aphid, Aphis spiraecola Patch, differed significantly in susceptibility to a number of insecticides registered for control of aphids on apple (Malus spp.). Compared with A. pomi, A. spiraecola was approximately four- and three-fold less su...

Methanol leaf extracts of two Ethiopian traditional medicinal plants viz., Lomisar [vernacular name (local native language, Amharic); Cymbopogon citratus (DC) Stapf. (Poaceae)] and Bisana [vernacular name (local native language, Amharic); Croton macrostachyus Del. (Euphorbiaceae)] were screened for larvicidal activity against late third instar larvae of Anopheles arabiensis Patton, a potent mal...
