“…The idea of an evolutionary relationship between MBSP and corn plants came from the study of the genus Dalbulus and its relationship with corn plants (Nault and Delong 1980). Southern Mexico has been considered the center of diversity and speciation of the genus Dalbulus, a genus that includes the reported MBSPvectors, and is also the center of evolution and domestication of maize from teosinte (Zea mays ssp.…”

“…Southern Mexico has been considered the center of diversity and speciation of the genus Dalbulus, a genus that includes the reported MBSPvectors, and is also the center of evolution and domestication of maize from teosinte (Zea mays ssp. Parviglumis) (Nault and Delong 1980;Doebley 2004). The 'corn leafhopper' (Dalbulus maidis), and the 'Mexican corn leafhopper' (Dalbulus elimatus), showed a natural preference for corn as a food source and a .…”

“…For the rest of the strains the accession number refers to the Cpn60-encoding gene * Key position to differentiating strains MBS-Pue, and MBS-Ver reproductive host, and a high rate of tolerance to the MBSP infection and efficient subsequent transmission (Nault and Delong 1980;Nault 1980Nault , 1983. The relationship among corn, Dalbulus leafhoppers, and MBSP has been maintained since the detection of the disease, and reported throughout the Americas, suggesting a biological differentiation and specialization.…”

In the 2013-2014 growing season, field surveys were conducted in native corn fields located in high altitude agricultural communities in the 'Sierra Norte de Puebla' in Mexico. Symptoms typical of maize bushy stunt (MBS) disease were observed and DNA extracted from symptomatic native corn plants was used as template to confirm the presence of phytoplasmas.Amplification and sequencing of 16S rRNA-encoding sequences and chaperonin 60 universal target (cpn60 UT) sequences followed by in vitro restriction fragment length polymorphism and phylogenetic analyses revealed that the phytoplasma detected belongs to the subgroup 16SrI-B, 'Candidatus Phytoplasma asteris'. Based on 16S rRNA-encoding gene sequence analysis and on a single nucleotide polymorphism within the cpn60 UT sequence, two MBS strains, MBS-Puebla and MBS-Veracruz, were identified. This is the first detection of MBS phytoplasma (MBSP) affecting native corn and the first molecular survey made in corn fields in Mexico to detect and characterize MBSP. We discuss these results in light of the potential evolutionary relationship between corn and MBSP.

Little is known about the host-parasitoid interactions on the edges of crops during winter. Our objective was to determine the parasitoid species that attack nymphs and adults of leafhoppers and planthoppers, and evaluate the interactions that occur during winter on maize edges. Between January and June of 2014 and 2015 leafhoppers and planthoppers with evidence of parasitism by Dryinidae (Hymenoptera) were collected on grasses that grow in maize fields margins in Mexico and were maintained alive until parasitoid adult emergence. Dryinids such as Gonatopus huggerti (Olmi), Gonatopus mimoides (Perkins), Gonatopus breviforceps (Kieffer), and Gonatopus caraibicus (Olmi) were the most common parasitoids. They attacked several leafhopper species such as Dalbulus maidis (DeLong), Balclutha incisa (Matsumura), Exitianus picatus (Gibson), and Stirellus bicolor (Van Duzee). The connection of the net was of 31%. The presence of parasitoids in winter margins highlights the importance of conserving maize edges for biological control.

“…There is a close association among RFV, D. maidis, and the maize plant; both virus and vector are almost totally restricted in nature to this particular host plant [2], Evi dence of coevolution of maize and Dalbulus species in Meso America has been presented recently [15], and it has been proposed that RFV, the maize stunt spiroplasma, and the maize bushy stunt mycoplasma played an im portant role in the evolution of maize and its ancestors [16]. The characteristics of the bio logical relationship among RFV, D. maidis, and their maize host are suggestive of co evolution of this living system in a tropical environment [2,17].…”

Discrete groups of 20- to 25-nm isometric particles, considered to represent maize rayado fino virus (RFV), were consistently observed in the ectoderm, fat body, midgut, follicular cells of the ovary, muscle, and salivary glands of RFV-infected Dalbulus maidis. The particles commonly occurred within cytoplasmic bodies bound by membranes, some of them resembling lysosomes, and were not found in nonviruliferous insects. These findings are congruent with previous studies on the multiplication of RFV in D. maidis. The absence of cytopathologic effects due to viral infection at the ultrastructural level confirms biological data on the absence of deleterious effects of the virus in its vector.
