THE methods hitherto employed in the study of the gross metabolism of insects have been based mainly on the changes in their content of physiologically important substances during development, and on the ability of the organism to grow on selected diets of known composition. There is a third method, extensively employed by mammalian physiologists, namely analysis of excreta; this, as Uvarov (19...

We investigate the nonrelativistic magnetic effect on energy spectra, expectation values of some quantum mechanical observables, and diamagnetic susceptibility for diatomic molecules bounded by isotropic oscillator plus inverse quadratic potential. The eigenvalues normalized wave functions are obtained via parametric Nikiforov-Uvarov method. square position <math xmlns="http://www.w3.org/1998/M...

We examine the bound state solutions of Dirac equation under spin and pseudospin symmetries for a new suggested combined potential, Hulthén plus class Yukawa potential including Coulomb-like tensor interaction. An improved scheme is employed to deal with centrifugal (pseudocentrifugal) term. Using Nikiforov–Uvarov SUSYQM methods, we analytically develop relativistic energy eigenvalues associate...

It has long been known that the physical factors of the environment exert profound effects on the various physiological activities of insects, and that temperature is one of the most important of these factors (Uvarov, 1931; Wigglesworth, 1953; Bursell, 1964). Within a biological range the reproductive activity of insects, like any other biological process, is enhanced by rise in temperature, b...

To identify the susceptibility of long-horned grasshoppers to entomopathogenic fungi, the effect of infection with the fungi Beauveria bassiana (Balsamo) Vuillemin (Hypocreales: Clavicipitaceae) and Metarhizium anisopliae (Metchnikoff) Sorokin (Hypocreales: Clavicipitaceae) on food consumption by Uvarovistia zebra (Uvarov) (Orthoptera: Tettigoniidae) was investigated. Preliminary results showed...
