Cytology of Nilaparvata bakeri (Muir), a grass-infesting planthopper (Homoptera: Delphacidae)

open access: yesCYTOLOGIA, 1985
The genus Nilaparvata Distant comprises 14 determined and 2 undetermined species which have been recorded from tropical and temperate zones throughout the world (Okada 1977, Mochida and Okada 1979). About one-half of these are known in Asia and the Pacific region and the remaining in Africa and Central Amer ica. Two of these species-N.

Generalist predators function as pest specialists: Examining diet composition of spiders and ladybeetles across rice crop stages

open access: yesJournal of Applied Ecology, Volume 62, Issue 8, Page 1889-1901, August 2025.
By quantifying the diet composition of GAPs over crop stages, farm types and years, this study reveals that generalist predators have potential to produce a stable, predictable top‐down effect on pests in rice agro‐ecosystems. Therefore, promoting the field densities of ubiquitous generalist predators will likely enhance pest management and support ...

Effect of Pest Control Strategies on Arthropod Pests of Apple in Europe: A Meta‐Analysis

open access: yesJournal of Applied Entomology, Volume 149, Issue 6, Page 957-987, July 2025.
ABSTRACT Apple (Malus domestica Borkh.) is a major fruit crop in Europe. More than 200 phytophagous arthropod species thrive in European apple orchards, several of which are economically important pests. Due to the pest pressure on apple production, consumer demand for residue‐free products and current policies to make food production in the European ...

Biology of the Planthopper Sogatella furcifera HORV. in Egypt (Horn., Delphacidae)

open access: yesDeutsche Entomologische Zeitschrift (neue Folge), 1980
The planthopper Sogatella furcifera (HORV.) was reared on wheat seedlings, inside large wire cages placed in the open, at Kafr-el-Sheikh, Egypt (about 130 Km north of Cairo). Egg incubation period averaged 7.1 days at 23-34 °C, 9.3 days at 17-28 °C and up to 21 days at 13-22 °C. Egg hatchability averaged 64.3-88.9%. Total nymphal durations were 13.8-15.

Evidence for high dispersal ability and mito-nuclear discordance in the small brown planthopper, Laodelphax striatellus [PDF]

open access: yes, 2015
Understanding dispersal ability in pest species is critical for both theoretical aspects of evolutionary and population biology and from a practical standpoint, such as implementing effective forecasting systems.

Phylogenomic insights into the relationship and the evolutionary history of planthoppers (Insecta: Hemiptera: Fulgoromorpha) 基于基因组的系统发育分析为蜡蝉亚目(Fulgoromorpha)的系统发育关系及进化提供新见解

open access: yesSystematic Entomology, Volume 50, Issue 3, Page 495-518, July 2025.
Using genomic data from 285 species across 19 planthopper families, we conducted the first phylogenomic study targeting global planthoppers and inferred their phylogeny with the highest resolution so far. We proposed taxonomic changes including the establishment of a new family Borysthenidae stat. rev. and a new superfamily Meenoploidea superfam.

Eyes on nature: Embedded vision cameras for terrestrial biodiversity monitoring

open access: yesMethods in Ecology and Evolution, Volume 15, Issue 12, Page 2262-2275, December 2024.
Abstract We need comprehensive information to manage and protect biodiversity in the face of global environmental challenges, and artificial intelligence is required to generate that information from vast amounts of biodiversity data. Currently, vision‐based monitoring methods are heterogenous; they poorly cover spatial and temporal dimensions, overly ...

Ecological and evolutionary consequences of temporal variation in dispersal

open access: yesEcography, Volume 2024, Issue 2, February 2024.
The importance of dispersal rates and distances has long been appreciated by ecologists and evolutionary biologists. An emerging field of research is revealing how temporal variation in dispersal can substantially influence ecological and evolutionary outcomes.

Diapause Induction and Termination in the Small Brown Planthopper, Laodelphax striatellus (Hemiptera: Delphacidae)

open access: yesPLoS ONE, 2014
The small brown planthopper, Laodelphax striatellus (Fallén) enters the photoperiodic induction of diapause as 3rd or 4th instar nymphs. The photoperiodic response curves in this planthopper showed a typical long-day response type with a critical daylength of approximately 11 h at 25 °C, 12 h at 22 and 20 °C and 12.5 h at 18 °C, and diapause induction ...
