“…The prominent TI activity was evidenced through wider protective zones against trypsin as compared to chymotrypsin during gelatin in-gel activity staining (Figure 2F). However, the existence of BBI as several isoinhibitors is a part of plant defensive trait to combat against pests and their counter defense (Giri et al, 2003;Lopes et al, 2004;War et al, 2018).…”

“…armigera uses multiple defense strategies while feeding upon various host plant material. The digestive proteases and their flexibility in expression play a prime role in contributing a major support for its survival, adaptability and polyphagous nature (Padul et al, 2012;Macedo et al, 2015;Zhu-Salzman and Zeng, 2015;War et al, 2018;Jamal et al, 2019). At any given time, alkaline trypsin-like serine proteases are the major constituents of midgut, inspite of changes in digestive protease profile with developmental stage and type of diet it consumes.…”

“…On the other hand, PIs are known to play a role in the regulation of programed cell death and tolerance against abiotic stress (Drame et al, 2013;Boex-fontvieille et al, 2015). Several studies demonstrated the use of PIs in the management of agriculturally important insect pests (Shamsi et al, 2016;War et al, 2018;Clemente et al, 2019). In this regard, serine PIs such as Kunitz and Bowman-Birk inhibitors (BBIs) are receiving considerable attention as a part of Integrated Pest Management (IPM) since lepidopteran insect pests depend predominantly on trypsin-and chymotrypsin-like digestive proteases for attaining energy (Sharma et al, 2000;Srinivasan et al, 2006;Swathi et al, 2016).…”

“…Plants are exposed to many types of mechanical stresses caused by both biotic and abiotic factors. Biotic causes of mechanical injuries include insect attacks, infestations by parasites and many organisms that feed on plants that have evolved mechanisms to protect themselves from mecha-nical injuries during their evolution (Ashry & Mohamed, 2011;Mohamed et al, 2012;War et al, 2018). Peroxidases and easily soluble proteins are among the factors that actively respond to cell damage by insects (Esteban-Carrasco et al, 2001;Deans et al, 2016).…”

The search for promising plants with bactericidal and fungicidal activity is of great interest for practical and veterinary medicine, This article reveals the high antibacterial effect of the use of ethanol extracts from 8 species of plants of the families Anacardiaceae (Cotinus coggygria Scop., Rhus typhina L., Rhus trilobata Nutt. and Toxicodendron orientale Greene), Araliaceae (Hedera helix Linnaeus and Aralia elata (Miq.) Seem.), Phyllanthaceae (Leptopus chinensis (Bunge) Pojark.), Berberidaceae (Mahonia aquifolium (Pursh) Nutt.) against 23 strains of bacteria and one strain of fungi. The in vitro experiment revealed the zone of inhibition of growth of colonies exceeding 8 mm during the application of ethanol extracts of C. coggygria against twelve species of microorganisms (Enterococcus faecalis, Escherichia coli, Staphylococcus aureus, S. epidermidis, Bacillus cereus, Listeria ivanovi, Corynebacterium xerosis, Rhodococcus equi, Proteus vulgaris, P. mirabilis, Serratia marcescens and Candida albicans), Rhus typhina – against twelve species (E. faecalis, E. coli, S. aureus, S. epidermidis, L. ivanovi, C. xerosis, Rh. equi, P. vulgaris, Salmonella typhimurium, S. adobraco, S. marcescens and C. albicans), Rhus trilobata – against fourteen (E. faecalis, E. сoli, S. аureus, S. epidermidis, B. subtilis, B. cereus, L. ivanovi, C. xerosis, Rh. equi, P. vulgaris, P. mirabilis, Рseudomonas аeruginosa, Yersinia enterocolitica and C. albicans), Toxicodendron orientale – against eleven (E. faecalis, S. аureus, L. іnnocua, C. xerosis, Campylobacter jejuni, Rh. equi, P. vulgaris, P. mirabilis, Р. аeruginosa and C. albicans), Hedera helix – against seven (S. аureus, S. epidermidis, L. monocytogenes, C. jejuni, Rh. equi, P. vulgaris and C. albicans), Aralia elata – against nine (E. coli, S. aureus, B. cereus, C. xerosis, P. vulgaris, P. mirabilis, S. typhimurium, S. marcescens and C. albicans), Leptopus chinensis – only against four (E. coli, S. epidermidis, B. cereus and P. mirabilis) and Mahonia aquifolium – against only three species (S. epidermidis, C. jejuni and P. vulgaris). As a result of the research, the most promising for studying in future regarding in vivo antibacterial activity were determined to be C. coggygria, Rhus typhina, R. trilobata, Toxicodendron orientale and Aralia elata.

Toxicity of Neem Cake Extract (Azadirachta indica) to Aphis glycine on Soybean Plant

2019

View full text Add to dashboard Cite

Aphis glycine is one of the soybean pests that can develop rapidly and cause yield loss. Neem is a plant known as botanical incesticide. This study tested the toxicity of neem cake against A. glycine and its effect on increasing tannin content in the soybean plant. The effect of neem cake extract to the mortality of A. glycine was tested by spray method and root dipping method. The application was carried out on four-week-old soybean plants with 10 individual of adult A. glycine as test insects. Observations were carried out every day for 8 DAT (day after treatmen) by counting the population of A. glycine. The testing of tannin levels and azadirachtin content is done by applying neem cake extract using root dipping method. The treatment is divided into two groups, which are infested plants and non-invested plants by A. glycine. The leaf of soybean (fourth day after application) was taken as samples for tannin and azadirachtin analysis. The results showed that the extract of neem cake at the spray method caused the death of A. glycine up to 97% at a concentration 2.5%. The root dipping method could make mortality of nymphs (new born) 100% at concentrations of 0.1% and 0.125% at 8 DAT , but cannot make mortality to adult of A. glycine. The tannin content in soybean plants (with A. glycine and without A. glycine invested) was increased after 0.125% neem cake application. Azdirachtin uptake was not detected at concentrations of 0.125% and 0.250% at 5 DAT. Neem cake extract can suppress A. glycine population in soybean plants and increase of tannin content in plants.
