The conversion of land functions can result in a decrease environmental quality, which reduce the diversity butterflies. This study aimed to determine level and find most abundant less butterfly species around campus 4 UAD. sampling was done at area, vacant land, rice fields housing sites. Each these sites had 2 plots consisted 5 subplots, respectively. Sampling carried out four times, morning ...

Developing efficient sampling protocols is essential to monitor crop pests. One vector of the citrus disease HLB, African psyllid Trioza erytreae Del Guercio, 1918 (Hemiptera: Triozidae), currently threatens lemon industry throughout Mediterranean region. In this work, a pool methods devoted monitoring population T. was compared, its spatial distribution in orchard assessed, and minimum effort ...

Arthropod diversity between disturbed and undisturbed habitats was studied. Arthropods are organisms that have six or more jointed legs, there are numerous in species and can be found in several different habitats. In our experiment, we wanted to test if there was a significant difference in arthropod diversity between undisturbed and disturbed areas of South Florida. We focused on two Miami-Da...

Non-spectral matrix effects in ICP-MS are often corrected by the method of internal standardisation. In the case of discrete sampling a common algorithm refers to the ratio of either maxima or areas of both analyte and internal standard peaks. The current work describes a protocol for internal standardisation across the transient peak based on the calculation of analyte-to-internal standard rat...

Sweeping moving objects has become one of the basic geometric operations used in engineering design, analysis and physical simulation. Despite their relevance, computing the boundary of the set swept by a non-polyhedral moving object is largely an open problem due to well known theoretical and computational difficulties of the envelopes. We have recently introduced a generic point membership cl...

We have applied the SRIM computer code to study the sputtering of some likely astrophysical grain materials, and we have shown that selective embedding of metallic projectiles offers a partial explanation of gas-phase depletions. We show that supernova shockwaves sweep a significantly larger mass of interstellar gas per unit time than the shockwaves generated by outflows in star-forming regions...

A series of field experiments was conducted in cranberry bogs in 2006e2010 to determine adult attraction of the two most economically important leafhopper pests of cultivated Vaccinium spp. in the northeast USA, the blunt-nosed leafhopper, Limotettix vaccinii (Van Duzee), and the sharp-nosed leafhopper, Scaphytopius magdalensis (Provancher), to colored (yellow, green, red, blue, white, and clea...
