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

Deutsche 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.

‘Candidatus Phytoplasma solani’: From infection to all‐round characterisation of distinct tuf‐type strains with different virulence in tomato plants

Annals of Applied Biology, Volume 188, Issue 2, Page 480-494, March 2026.
‘Candidatus Phytoplasma (Ca. P.) solani’ is associated with bois noir (BN) of grapevine and stolbur of solanaceous plants and is primarily transmitted by Hyalesthes obsoletus Signoret. Four tuf‐a and five tuf‐b1 ‘Ca. P. solani’ strains were transmitted to tomato plants (cv. Micro‐Tom) by using bait‐plants and by capturing H.

Antimetabolic effects of plant proteins on homopteran insect pests [PDF]

, 1993
Homopteran insect pests can cause severe economical damage to crop plants by both direct physical means and as vectors of plant viral diseases. They are notoriously difficult insects to control by conventional methods, primarily due to their ability to ...

Landscape Genomics and Evolutionary History of Megamelus scutellaris, a Biocontrol Agent of the Invasive Water Hyacinth (Pontederia crassipes)

Evolutionary Applications, Volume 19, Issue 2, February 2026.
ABSTRACT Understanding the evolutionary history of biological control agents in their native ranges is crucial for improving their selection, establishment, and performance across environmentally diverse regions. Phytophagous insects that specialize on aquatic plants offer particularly valuable models, as their evolutionary trajectories may be shaped ...

Exploring the Influence of Insect Honeydew on Plant Physiology and Health: Bridging the Gap in Current Understanding

Physiologia Plantarum, Volume 177, Issue 6, November/December 2025.
ABSTRACT Honeydew, a sugary excretion from sap‐feeding insects, significantly influences plant‐insect interactions. While extensive research has examined honeydew's composition, regulation, and role in insect‐plant relationships, its direct effects on plant physiology and health remain understudied.

Primary and Secondary Symbionts of Cambodian Cicadellidae and the Role of Parasitisation

Environmental Microbiology Reports, Volume 17, Issue 5, October 2025.
Leafhoppers are key agricultural pests, and their interactions with parasitoids may be influenced by microbial symbionts. In this study, we characterized the bacterial communities of six Cambodian leafhopper species and their parasitoids, finding that while Sulcia dominates leafhopper microbiotas, parasitoids exhibit higher microbial diversity.

Genomic Analysis Reveals Annual Variation in the Migratory Pathways to East Asia in the Brown Planthopper (Nilaparvata lugens)

Evolutionary Applications, Volume 18, Issue 10, October 2025.
ABSTRACT The brown planthopper (BPH, Nilaparvata lugens) is a major rice pest in Asia, causing significant yield losses. As BPH cannot overwinter in temperate regions, East Asian populations are wind‐borne migratory insects originating from tropical regions. The identification of precise migratory patterns is essential for forecasting BPH outbreaks and
