While Mexican lime is an economic tree species, its fruits are prone to postharvest diseases caused by fungal species of the genus Penicillium, which can inflict severe economic loss. To alleviate these adverse effects, there has been a rise in interest for environmentally-friendly treatments in the fruit industry due to consumers' concern for food...
Genetic variation, as a multi-scalar variable, is important to genetic resource and conservation programs.

The date palm hopper, Ommatissus lybicus de Bergevin, is one of the most important pests of the date palm in the Middle East and North Africa. This insect uses its needle-like sucking mouthparts to feed on phloem, which is devoid of most essential amino acids and many vitamins. The absence of essential nutrient in its diet is suggested to be amelio...

Study of genetic structure of Ommatissus lybicus de Bergevin revealed significant variation among the allopat-ric populations of this pest. High biological and behavioral variation suggest either that this is a highly variable pest species or a complex with a mix of cryptic species. The degree of reproductive isolation was tested by crossing experi...
Samples of Suaeda aegyptiaca with phytoplasma symptoms such as witches' broom, yellowing and little leaf were observed in Bandar Abbas (Hormozgan Province, Iran) in 2016. Using PCR assays, the symptomatic plants tested positive for phytoplasma. Results of phylogenetic analyses of the 16S rRNA gene sequences revealed that the phytoplasma associated...
Disease symptoms resembling those associated with phytoplasmas were observed in Manilkara zapota (sapodilla) trees in Hormozgan province, Iran. A nested po-lymerase chain reaction using phytoplasma universal primers was used to detect phytoplasmas in symptomatic trees. Amplification and sequencing of a 1.2-kb 16S rDNA fragment confirmed that sapodi...
Worldwide distribution of the Date Palm Hopper (DPH), Ommatissus lybicus de Bergevin along with intensive regional chemical and cultural practices to control this pest provide a basis for development of high genetic divergence. This genetic divergence can result in demographically distinct populations. In this study, the demographic parameters of t...

Developmental time and body size correlate with lifespan in a wide range of taxa, although not in insect parasitoids. When the rate of development is independent of adult metabolic rate, adult lifespan is free to adapt to the adult environment. We suggest that interspecific variation in intrinsic adult metabolic rates, differences in allocation of...
The genetic structure of populations can be influenced by geographic isolation (including physical distance) and ecology. We examined these effects in Leptopilina boulardi, a parasitoid of Drosophila of African origin and widely distributed over temperate and (sub) tropical climates.
We sampled 11 populations of L. boulardi from five climatic zones...

1. Climate is an important source of selection on life histories, and local adaptations to climate have been described in several cline studies. Temperature is the main climatic factor that has been considered as an agent of selection, whereas other factors may vary with it, such as precipitation.
2. We compared life-history traits of five populati...
In this thesis I studied the relationships between parasitoids, hosts and climate from an evolutionary point of view by using hymenopteran parasitoids as a model system. A comparative approach was used to study the variation in life-history traits of species or populations from different habitats. I showed that closely related species manipulate th...

Few examples exist where parasites manipulate host behaviour not to increase their transmission rate, but their own survival. Here we investigate fitness effects of parasitism by Asobara species in relation to the pupation behaviour of the host, Drosophila melanogaster. We found that Asobara citri parasitized larvae pupate higher in rearing jars co...
Questions
Question (1)
I have a data set exported in excel from presence and absence of bands in an AFLP analysis (dominant markers). I have done a lot of work with R but I am trying to make a phylogeny using R, which I am confused in formatting this data for dendrogram. Is there anybody to give me an example of correct format for this data set and also related script and package I need in R for analyzing and plotting phylogeny tree?
