Dispersion Pattern of Giant Cicada (Hemiptera: Cicadidae) in a Brazilian Coffee Plantation

Abstract

The giant cicada Quesada gigas (Olivier, 1790) (Hemiptera: Cicadidae) is a major pest of coffee plants in Brazil. To ensure the rational management and ecological equilibrium, information about the behavior, dispersion, and reproduction of giant cicada is fundamental. The present work was conducted in an area of 97 ha planted with Coffea arabica L. to investigate adult dispersion as well as mating and oviposition behaviors of Q. gigas. A sound trap was placed at a ‘release point’ used for the attraction, marking, and release of adults in the area. The recapture of insects was performed with the same sound trap positioned at 20 points distributed at 100, 250, 400, and 1,000 m from the release point. The highest recapture rates of Q. gigas were observed at 100 m from the release point, and the lowest recapture rates were observed at 1,000 m. The presence of Eucalyptus plants in the area apparently influenced dispersion, as high recapture rates were observed at the sites close to Eucalyptus plants. One copulation of Q. gigas lasted 41.6 ± 0.43 min, and the period of a single oviposition bout was 30.0 ± 0.20 min. Quesada gigas adult longevity in the field was estimated to be 49 d. Both males and females were observed performing multiple matings.

Selymbria Stål, 1861 (Hemiptera: Cicadidae: Tibicininae): description of a new species with notes on the genus taxonomy and distribution

“…nov. occurs in the Imerí province in Brazil (Boreal Brazilian dominion), but also includes records from the east and west Amazon forest in the Madeira province (South Brazilian dominion) which are ~1,000 km apart. The dis-persal capacity in cicadas is thought to be relatively low with current dispersal estimates below a one-kilometer radius (Karban, 1981;Andrade et al, 2020). Most of the distance observed between the locality data collected here is due to low collecting efforts.…”

The effect of the Messinian salinity crisis on the early diversification of the Tettigettalna cicadas

“…Adult cicadas are short‐lived (1–6 weeks) and need to feed daily on plant sap, turning long travelling overseas without feeding sources on the way into a risky endeavour. Dispersal in cicadas seems to occurs mostly in a step‐wise fashion, with travel distances reported as not exceeding 1 km for large‐body Quesada gigas (Andrade et al, 2020), 500 m for Cicada orni (Simões & Quartau, 2007), or 150 m for Magicicada spp . (Karban, 1981).…”

Reforestation provides a foraging habitat for brown bears (Ursus arctos) by increasing cicada Lyristes bihamatus density in the Shiretoko World Heritage site

“…Given that the plantations are located proximate to the natural forests in the study site (see Fig. 1) and dispersal distance in adult cicadas is estimated at about 100-250 m (Andrade et al 2020), adult cicadas can easily come and go between the plantations and the natural forest. Since emergence schedule in cicada is usually homogeneous within same population (e.g.…”
