Boric acid, imidacloprid, and thiamethoxam in sucrose aqueous baits had different delayed toxicities to worker Argentine ants, Linepithema humile (Mayr). The concentrations required to produce an LT50 (time required to produce 50% mortality) within 1-4 d were 3.63-0.55% boric acid, 9.2 x 10(-3) to 7.1 x 10(-4)% imidacloprid, and 3 x 10(-4) to 2 x 10(-5)% thiamethoxam. The three toxicants were n...

New insecticides that exhibited high compatibility with environment components are very promising substitutes for control of the economic insects. Simi-field experiments were conducted on profenofos and four novel insecticides viz., spinosad, emamectin-benzoate, pyridalyl and indoxacarb to investigate their efficiency and the field persistence of their residues against 4 instar larvae of the co...

Lipas jerman telah resisten terhadap berbagai macam insektisida, dibuktikan dengan adanya kasus resistensi lipas yang dilaporkan terjadi di beberapa wilayah Indonesia. Meskipun demikian, Kota Purwokerto sampai saat ini belum ada laporan mengenai tersebut. Tujuan khusus penelitian adalah mengetahui status dari tiga pasar tradisional fipronil. Metode digunakan metode kontak dan umpan menggunakan ...

The frost hardiness of many plants such as chickpea can be increased by exposure to low non-freezing temperatures and/or the application of abscisic acid (ABA), a process known as frost acclimation. Experiments were conducted to study the response over a 14 d period of enriched plasma membrane fractions isolated from chickpea plants exposed to low temperature and sprayed with exogenous ABA. Mea...

in this research, the bud and cane winter cold tolerance of 22 field-grown grapevine cultivars of kourdestan province agricultural and natural resources research and education center was evaluated at jan. and mar. stages in 2012. in these cultivars soluble carbohydrates and water content changes of buds and canes during dormant period also were measured. after exposure to different freezing tem...

Several animal models have been used to understand the molecular basis of the pathogenicity, infectious dose and strain to strain variation of Listeria monocytogenes. The greater wax worm Galleria mellonella, as an alternative model, provides some useful advantages not available with other models and has already been described as suitable for the virulence assessment of various pathogens includ...

The laboratory experiments were carriedout at the Institute of Organic Farming (IOF), UAS, Dharwad, during 2014-2015 to study bioefficacy different formulations Metarhizium anisopliae against coconut rhinoceros grubs, Oryctus (Linnaeus). Among oil based formulation, rice bran (60%) + corn (40%) formulation found least LC50 value (1.99 x 106 cfu/ml) 432 h. In granular and wettable powder recorde...

Dehydrins exist widely in plants and play an important role abiotic stress resistance. Two low-temperature-induced dehydrin-like genes, PmCAP LpCAP, from the pine species Pseudotsuga menziesii Larix principis-rupprechtii Mayr were cloned found to contain 576 bp 687 bp, encoding 191 228 amino acids, respectively. Both genes individually assembled into prokaryotic expression vectors transferred E...
