Th is study has two main approaches. First, it exploits the susceptibility of tomato cultivars as a prophylactic measure to detect auto resistance characters of the tested tomato varieties against Bemisia tabaci (Gennadius) (Homoptera: Aleyrodidae). Secondly, it evaluates the effi cacy of diff erent bio-rational insecticides against B. tabaci under greenhouse conditions. Th e results exhibited a special signifi cance in B. tabaci infestation suitability between the two tomato varieties with a high infestation signifi cance found in the Shifa F1 hybrid tomato variety compared to the Savera F1 hybrid tomato variety in the fi rst plantation period. Subsequently, in the second plantation period, there was a signifi cant diff erence between the two tomato varieties. Bemisia tabaci showed a preference for the Shifa F1 hybrid over the Savera F1 hybrid tomato variety. Th ese diff erences occurred during the 1st, 2nd, 4th, 6th, 7th, 8th, and 10th weeks. In the experimental trial for the effi cacy of eco-friendly biorational insecticides, spinosad, azadirachtin, Beauveria bassiana and Metarhizium anisopliae, there were signifi cant diff erences between the treated and untreated plants during the two plantation periods. A high effi cacy of spinosad on the B. tabaci population was found. Bemisia tabaci infestation under all the applications was reduced from 50 to 94.61% for the two plantation periods. Th is obvious decrease in B. tabaci population increase attention to benefi ts of the diff erent bio-rational insecticides.

“…Biotype Q, recorded for the first time at the beginning of 1990s in Spain (Guirao et al 1997), has become a major pest in European Mediterranean regions, North Africa and Israel (Horowitz et al 2003;Simón et al 2007;Tsagkarakou et al 2007), and most recently, it has spread in the North and Central America, in East Asia and New Zealand (Chu et al 2007;Martinez-Carrillo and Brown 2007;Ueda et al 2009). Both biotypes, owing to their characteristics of strong polyphagy, high reproductive rate and high level of resistance to insecticides (Olivera et al 2001;Horowitz et al 2005;Roditakis et al 2005;Bonato et al 2007) represent a serious threat to cultivated plants in any area of invasion.…”

The genetic diversity of Bemisia tabaci was investigated in Southern Italy using the mitochondrial cytochrome oxidase I (COI) gene as molecular marker and sampling whiteflies on cultivated plants, weeds and bushes. Phylogenetic analysis of COI sequences and restriction analysis of COI amplicons were used to genotype whitefly populations. A PCR-RFLP method based on digestion with the endonuclease ApoI was set up to identify the B. tabaci genetic variants so far recorded from the Mediterranean region. In general, biotype Q populations were most frequently collected (76.0% of all sampled populations). In greenhouse districts, 87.0% sampled populations were identified as biotype Q, and 13.0% were assigned to biotype B. Outside the greenhouse districts, the biotype B was never collected, whilst biotype Q populations were found on weeds and on plants cultivated in family gardens in different environments, also located in interior plains or in mountain areas distant from intensive cultivations of whitefly host plants. A new genetic variant unrelated to B and Q biotypes, which was named Ru, was collected on Rubus ulmifolius and grapevine. Phylogenetic analysis of COI sequences shown that Ru haplotypes form a wellsupported clade sister to the clade including the Asian/ Australian major genetic groups and the Italy major genetic group. The closest relative of the Ru clade (10.7% pairwise genetic distance) was the Italy group, with this latter so far including only the haplotypes of the T biotype. These results were discussed in the light of the recent B. tabaci species concept.

Subsequent monitoring showed that MED was detected in Þeld crops such as cotton (Gossypium hirsutum L.), eggplant (Solanum melongena L.), tomato (Lycopersicon esculentum L.), pepper (Capsicum frutescens L.), and other vegetables in Beijing, Henan, Shandong, and Zhejiang (Chu et al 2006(Chu et al , 2007.

The Mediterranean group (commonly known as Q biotype; hereafter MED) of the sweetpotato whitefly, Bemisia tabaci (Gennadius), originated in the Mediterranean region, but it now has been found in at least 10 countries outside the Mediterranean. Collections of B. tabaci from some of these countries exhibit different pest behaviors and pesticide resistance characteristics, yet all may be classified as MED. A phylogenetic analysis of 120 mitochondrial cytochrome oxidase I (mtCOI) sequences (JN966761-JN966880) of MED whiteflies collected in Arizona and of 417 retrieved from the GenBank database resolves the MED into five subclades, designated as Q1-Q5. Only subclades Q1 and Q2 have been detected in the United States. Q1 and the other four subclades (Q2-Q5) differ in the number or position of the AluI recognition sites. Based on the differences in the AluI recognition sites reported here and the previously reported differences in VspI recognition sites, we developed a simple diagnostic technique to identify subclades Q1-Q5 by using mtCOI polymerase chain reaction (PCR)-restriction fragment-length polymorphism (RFLP). A test of a worldwide collection of whiteflies demonstrates that this combination mtCOIPCR-RFLP technique can reliably distinguish not only the MED from the Middle East-Asia Minor 1 group but also the Q1 from any of the other four MED subclades.
