With a growing world population and increasingly demanding consumers, the production of sufficient protein from livestock, poultry, fish represents serious challenge for future. Approximately 1,900 insect species are eaten worldwide, mainly in ...Read More
Abstract Mitochondrial 16S (~550 bp) and cytochrome oxidase I (COI) (~700 sequences were utilized as markers to reconstruct a phylogeography for representative populations or biotypes of Bemisia tabaci . exhibited less divergence than COI sequences. Of the 429 characters examined sequences, 185 sites invariant, 244 variable 108 informative. sequence identities yielded distances ranging from 1% greater 17%. Whitefly 456 analysed which consisted 298 invariant sites, 158 53 informative sites....
Summary Eighteen populations of Bemisia tabaci , collected from different geographic locations (North & Central America, the Caribbean, Africa, Middle East, Asia and Europe), were studied to identify compare biological genetic characteristics that can be used differentiate biotypes. The morphology fourth instar/pupal stage compound eye structures adults investigated using scanning electron microscopy found typical species among all biotypes studied. Setae spines B. larval scales same...
Abstract The sweetpotato whitefly Bemisia tabaci is a highly destructive agricultural and ornamental crop pest. It damages host plants through both phloem feeding vectoring plant pathogens. Introductions of B. are difficult to quarantine eradicate because its high reproductive rates, broad range, insecticide resistance. A total 791 Gb raw DNA sequence from whole genome shotgun sequencing, 13 BAC pooling libraries were generated by Illumina sequencing using different combinations mate-pair...
Envy is a pan-human phenomenon, universally feared, at least subconsciously, as particularly dangerous emotion, since it implies hostility and aggression capable of destroying individuals even societies. Especially in Western society, man has rather successfully repressed his true feelings about envy, which he taught the most shameful reprehensible all emotions. But while denying it, cultures found devices, but not are symbolic, to cope with fear consequences envy. In this paper I...
Evolution of resistance by pests is the main threat to long-term insect control transgenic crops that produce Bacillus thuringiensis (Bt) toxins. Because inheritance Bt toxins in typically recessive, DNA-based screening for alleles heterozygotes potentially much more efficient than detection resistant homozygotes with bioassays. Such screening, however, requires knowledge field populations are associated survival on crops. Here we report pink bollworm ( Pectinophora gossypiella ), a major...
The whitefly Bemisia tabaci (Hemiptera: Aleyrodidae) is among the 100 worst invasive species in world. As one of most important crop pests and virus vectors, B. causes substantial losses poses a serious threat to global food security. We report 615-Mb high-quality genome sequence Middle East-Asia Minor 1 (MEAM1), first Aleyrodidae family, which contains 15,664 protein-coding genes. highly divergent from other sequenced hemipteran genomes, sharing no detectable synteny. A number known...
Although sex division of labor is a universal, the contribution that women make to subsistence varies markedly from society society. It suggested here degree which participate in activities depends upon compatibility latter with simultaneous child‐care responsibilities. Women are most likely substantial when have following characteristics: participant not obliged be far home; tasks relatively monotonous and do require rapt concentration; work dangerous, can performed spite interruptions,...
Abstract Biological characteristics (oviposition and survival rates) esterase banding patterns in native PAGE were investigated to evaluate variation among three populations of Bemisia tabaci Gennadius (Homoptera: Aleyrodidae). Reproductive capabilities whiteflies from cotton ( Gossypium hirsutum L.) pumpkin Cucurbita maxima Duchesne) similar on the host plant species tested. These populations, which had same wild‐type field origin, reproduced better either than poinsettia Euphorbia...
The DNA of several monopartite and bipartite whitefly-transmitted (WFT) geminiviruses was amplified from a viral template present in infected leaves after either direct addition clarified plant extracts to an otherwise complete polymerase chain reaction (PCR) mix or immobilization microfuge tubes. A degenerate primer pair designed specifically target the middle 'core' region capsid protein gene subgroup III geminivirus isolates amplify fragment approximately 550 bp. Using this method, single...
The symbiotic bacterium Wolbachia pipientis has been considered unique in its ability to cause multiple reproductive anomalies arthropod hosts. Here we report that an undescribed is vertically transmitted and associated with thelytokous parthenogenetic reproduction Encarsia , a genus of parasitoid wasps. Although was found only one seven populations examined, the “ bacterium” (EB) other six. Among sexually reproducing screened, EB present one, none harbored . Antibiotic treatment did not...
The Q biotype of Bemisia tabaci (Gennadius), which has been described from the Mediterranean/North African region, was identified for first time infesting ornamental crop species in several locations China. Identification and partial distributions exotic B recently introduced China were established by using mitochondrial cytochrome oxidase I gene (mtCOI) as a molecular marker. Collections B. made representative geographical plant hosts different provinces MtCOI sequence analysis revealed...
The insect salivary enzyme glucose oxidase (GOX) can inhibit wound-inducible nicotine production in tobacco, Nicotiana tabacum. We examined whether gland extracts of Helicoverpa zea lacking active GOX could still suppress tabacum, and defenses another Solanaceous plant, tomato Lycopersicon esculentum. Tobacco leaves were wounded with a cork borer treated water, (SxG), or inactive (SxI). After three days, SxG had significantly less than all other treatments. Neonates that fed on the terminal...
Whiteflies (suborder Sternorrhyncha, family Aleyrodidae) are known to harbor prokaryotic symbionts, some of which vital and provide specific nutritional needs, while others transient or nonessential, that can either be beneficial deleterious in the long-term. However, extent diverse bacterial symbionts associated with populations same species whitefly colonize herbaceous plants habitats, their particular influence on evolution host, not well studied. Here, composition diversity biotypes...
