First report of the karyotype of Bufo dhufarensis from Saudi Arabia

Abstract

We report for the first time the description of the karyotype of the Dhufar toad Bufo dhufarensis from Saudi Arabia. This karyotype consists of 22 chromosomes and could be classified into two categories; eight pairs of metacentric and three pairs of submetacentric chromosomes. The 10th pair of this karyotype has a secondary constriction on the long arms of both male and female chromosomes. The fundamental number of this species is 44.

Effect of Zucchini Yellow Mosaic Virus on the fecundity and longevity of vector, the Aphid Aphis gossypii, in Souk Ahras (East Algeria)

“…In addition, the mean number of Aphids nymphs placed on the plants on a sound and courgettes over the life of infected insect's Aphids and Nymphs as noted in Figure 4. That the number of insects on plants nymphs the healthy is low than died on plants infected with the virus, and that the Aphids the number of insects that are placed on infected plants start decreasing gradually with time due to increased severity of viral infection by the plant pathogen courgettes and this consistent with what the (MARKKULA and LAUREMA, 1964), were attributed this phenomenon to provide the free amino acids for insects Aphids is less than concentrations in plants and the healthy badly infected with viral pathogen-infected plants compared with moderately increasing the fertility of the insect Aphids the last plants which could be seen clearly in this study (Figure 2AB and 3AB), it is clear that the most important problems that can result from the rapid multiplication of insects Aphids vectors of the virus is to increase the opportunities for the incidence of each of the epidemic insect Aphids as well as patients (ZYMV) in cultivated fields, especially of cucurbits and it has proven the ability of this type of Aphids the transfer of this virus in Souk Ahras (East Algeria) (AL- SHAHWAN, 1990) and as the damage caused by pathogens, viral diseases of plants is largely out of proportion with the population density of the insect vectors, the rapid multiplication of insects Aphids the infected plants will be encouraged to a large extent and increases the chances of contention and the movement of insect vectors carrying the virus to other plants healthy and, of course, compared to insect Aphids that feed on plants healthy and reproduce by the normal (WOODFORD et al, 1997).…”

“…Belongs yellow mosaic virus and green courgettes (ZYMV) to a Wi-potato virus (Potyvirus group), which is transmitted by several species of Aphids and a non-survivor (SUTIC et al, 1999), the fact, that the acquired and transported by Aphids in a very fast it takes only a few seconds and can be done during the tasting and explore the essence of the insects of plants infected with viral (HUNTER and ULLMAN, 1992). ZYMV is transmitted by Aphids, and there are at least ten types of carriers of the virus that causes the disease, and most notably the spread of a pest of watermelon and cotton is also called the Aphid Aphis gossypii = melon or cotton Aphid, which had proved its ability to transmit the virus (AL- SHAHWAN, 1990 andPERRING et al, 1992).…”

Emerging Antifungal Resistance in Falco Species: A Novel Model for Human Medicine

“…Fluconazole is an antifungal medication commonly used in the treatment of human medicine, but its efficacy in treating avian aspergillosis is limited [11,20,21]. There are several reasons why fluconazole may fail in the treatment of falcon aspergillosis.…”
