The puparium of Hermetia teevani Curran is described, based on 173 specimens reared from cassava roots (Manihot esculenta), in laboratory under controlled conditions until the emergence of the adults. Hermetia teevani is the ninth species with immature stage known for Hermetia, in addition to being recorded for the first time for the Distrito Federal and State of Gois.

Eubulus cf. elongatus Hustache (Coleoptera: Curculionidae) is a Neotropical species recently considered an important pest of cassava (Manihot esculenta Crantz) in Brazil. This weevil feeds on cassava roots under the soil, which makes detection and control by traditional methods as pesticide quite ineffective.

The corn leafhopper Dalbulus maidis (DeLong & Wolcott) is one of the most important maize (Zea mays L.) pests in Latin America because of its ability to efficiently transmit pathogens [maize bushy stunt phytoplasma (MBSP) and corn stunt spiroplasma-Spiroplasma kunkelli Whitcomb et al. (CSS)] associated with corn stunt disease complex and maize rayado fino virus (MRFV).

The corn leafhopper Dalbulus maidis is one of the most important pests of maize in Latin America. Here we report, for the first time, the natural occurrence of two fungal species infecting the adult stage of this pest. In 2020, insects killed by a pale bluish green fungus in irrigated maize fields located in Northeast Brazil were found attached to the abaxial surface of leaves.

Article Synopsis
  • Dalbulus maidis populations in northeastern and central-southern Brazil exhibit morphological differences, indicating possible genetic isolation.
  • A study was conducted using RAPD-PCR to analyze genetic differences among populations from five locations, revealing a high percentage of polymorphic loci (78%) and strong genetic similarity (over 0.72).
  • Gene flow estimates were high (up to 8.53) between central-southern populations, while the northeastern population from Mossoró/RN showed low gene flow and significant genetic isolation from the others.
