impact of sex pheromones, stirrup-m as additive for acaricides effects were evaluated on panonycjllls lllmi in 1995-1997. peroral (azocyclotin), amitraz (mitac), omite (propargite), neoron (bromopropylate) and citrazon (benzoximate) were tested with and without pheromones and compared with untreated plots with four replications through randomized complete block design. mortality percentage of e...
The present investigation was carried during year 2019-2020 at Division of Entomology, Faculty Agriculture, Wadura, Sopore. A total six larval instars Agrotis ipsilon, were noticed in three generations one calendar year, the study. average length and breadth from first to sixth cutworm caterpillars ranged between 1.88 -34.21mm 0.35-3.5mm respectively. Whereas, mean developmental durati...
This is the first field study in which we have tested efficacy of four different entomopathogenic fungal (EPF) formulations together single study—i.e., Green Muscle, Guard, Metarhizium anisopliae, and an isolate Beauveria bassiana (isolate WG-11)—against nymphs adults desert locust, Schistocerca gregaria Forskål (Orthoptera: Acrididae). We conducted several studies: (a) lethal bioassay against ...
The biology of predatory fly, Leucopis glyphinivora Tanas. was studied under greenhouse conditions. Adult longevity was 8 days and the average fecundity was 35.7 eggs. Incubation period, the 1st, 2nd, 3rd larval instars and puparium duration averaged 2.7, 2.16, 3.48, 5.7 and 8.45 days, respectively. Each generation lasted about one month. The predator efficiency was studied by applying the egg ...

in civil engineering concrete is a material combined of hydraulic cement, sand, gravel and water. gravel and sand compose 60 to 70 percent of concrete. these aggregates support compression force of concrete. cement paste acts as glue to stick grain together. in bushehr factories producing aggregates do not operate according to astm standards, so that fineness modulus (fm) of the produced sands ...
Chinavia Orian (1965) is one of the most diverse genera of Pentatomidae, distributed in the Afrotropical, Neotropical and Nearctic Regions. Thirty-two species are recorded for Brazil, some of them having potential economic impact because they are found on crops and referred to as pests. The morphology of the five nymphal instars of Chinavia armigera (Stål, 1859), Chinavia aseada (Rolston, 1983)...
insurers have in the past few decades faced longevity risks - the risk that annuitants survive more than expected - and therefore need a new approach to manage this new risk. in this dissertation we survey methods that hedge longevity risks. these methods use securitization to manage risk, so using modern financial and insurance pricing models, especially wang transform and actuarial concepts, ...
The effects of 16 sugars (arabinose, cellobiose, fructose, galactose, gentiobiose, glucose, inositol, lactose, maltose, mannitol (a sugar alcohol), mannose, melibiose, ribose, sorbitol, trehalose, and xylose) on sweet potato whitefly Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae) survival were determined using in vitro bioassays. Of these sugars, arabinose, mannose, ribose, and xylose were...
