“…Further collecting efforts are needed in unsampled areas. In contrast, some common species have been densely recorded in crop fields (Blanco-Rodríguez et al 2015, 2022Pinedo-Escatel & Moya-Raygoza 2015 and increasing numbers of records are being recorded by online platforms (e.g., iNaturalist).…”

Cicadellinae is a relatively large subfamily of leafhoppers (Hemiptera: Cicadellidae) with a cosmopolitan distribution with most genera known to occur in the Neotropics. Mexico houses nearly 16% of the total genera and most are endemic, inhabiting threatened native forests. Here, a new unusual Mexican genus, Christopherus gen. nov., is described to accommodate a new species of Cicadellini, C. mictlantecuhtli sp. nov., collected in the endangered Cloud Forest of Sierra Juárez, Oaxaca State of Mexico, based on dry-pinned museum specimen data. The new taxa can be separated from other Neotropical Cicadellini genera easily using male genitalia features: (i) pygofer without processes, (ii) segment 10th without processes, (iii) paraphysis absent, and (iv) edeagus with single basal atrial process elongate and asymmetrical. The monotypic genus Gillonella with its type species, G. ampulla Nielson & Godoy, 1995, are redescribed. A detailed extensive morphological description and discussion to distinguish the new genus from allied red-striped Neotropical genera in Mexico, Central America, and South America are given. Distributional data for new taxa within Mexican forests is also provided.

“…At the onset of the winter season, cultivated maize plants start to dry out, and D. maidis adults begin to disperse locally or perform long migrations ( Oliveira et al 2013 ). In central Mexico, corn leafhopper adults disperse temporally from November to January to green grasses that inhabit the maize field edges ( Pinedo-Escatel and Moya-Raygoza 2015 ) or move to volunteer maize, uncultivated maize found during winter in several countries of the Americas ( Summers et al 2004 , Carloni et al 2013 , Oliveira et al 2013 ). Edge grasses and volunteer maize are overwinter habitats for D. maidis egg parasitoids such as Mymaridae and Trichogrammatidae species ( Moya-Raygoza and Becerra-Chiron 2014 ).…”

Little is known about Dalbulus maidis (DeLong) egg parasitoids within maize fields, in the edge zones that surround these fields, and the parasitism on D. maidis eggs oviposited on different maize varieties. The objectives of the present study were first to understand which egg parasitoid species attack D. maidis eggs within maize fields and in the surrounding edge zones, and second, to compare parasitism on two maize varieties (land race Ancho-pozolero and hybrid Tigre-Asgrow) during the maize-growing wet season. We used maize plants with sentinel eggs to attract the egg parasitoids in two consecutive wet seasons, in 2015 and 2016. In 2015, Anagrus sp. (Hymenoptera: Mymaridae) and Paracentrobia sp. (Hymenoptera: Trichogrammatidae) parasitized D. maidis eggs within the maize field and on its edges. However, much more parasitism was seen within the maize agroecosystem than in the maize edge zones. In 2016, two Mymaridae species, Anagrus columbi Perkins and Anagrus sp, and two Trichogrammatidae genera, Pseudoligosita sp. and Paracentrobia sp., attacked the D. maidis eggs laid on maize hybrids but not those oviposited on the maize land race. Our findings indicate that parasitism of corn leafhopper eggs differs with agroecosystem location and maize varieties.

“…(Hemiptera: Cicadellidae). Leafhoppers that occur during the winter season on perennial grasses bordering maize fields are diverse with S. bicolor, Graminella sonora (Ball), Dalbulus elimatus (Ball), D. maidis, B. incisa, and Exitianus picatus (Gibson) (Hemiptera: Cicadellidae) being the most abundant species (Pinedo-Escatel and Moya-Raygoza 2015). However, none of the previous species were found to be positive for CSS or MBSP, suggesting that these two bacteria do not pass the winter in leafhoppers that overwinter on edge grasses (Torres-Moreno et al 2015).…”

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.
