Infection Models for Pine Wilt Disease on the Basis of Vector Behaviors

open access: yesPopulation Ecology, Volume 68, Issue 1, January 2026.
Infection models for pine wilt disease without vector density were built to estimate the transmission coefficient of the pathogenic nematode. The models successfully simulated the annual change in the density of infected trees for four pine stands. ABSTRACT Pine wilt disease is caused by the pinewood nematode (Bursaphelenchus xylophilus Steiner et ...

Effect of quinclorac-resistant Echinochloa spp. on the microbiota structure and function of Laodelphax striatellus(二氯喹啉酸抗性稗草对灰飞虱体内微生物群落结构及功能的影响)

open access: yes浙江大学学报. 农业与生命科学版
Quinclorac-resistant Echinochloa spp. can promote the growth and reproduction of Laodelphax striatellus, which is closely related to the microbiota in vivo.

A plant virus attenuates the Toll immune pathway by degradation of Pellino to facilitate viral infection in insect vectors

open access: yesJournal of Virology
Many plant viruses are persistently transmitted by insect vectors. The viral antagonism of insect innate immune responses is a critical step in ensuring persistent viral infection.

The complete mitochondrial genome of Aphis gossypii Glover, 1877 (Hemiptera: Aphididae) isolated from Plantago asiatica in Korea

open access: yesMitochondrial DNA. Part B. Resources, 2020
We have determined mitochondrial genome of A. gossypii isolated from Plantago asiatica in Korea. The circular mitogenome of A. gossypii is 16,045 bp including 13 protein-coding genes, two ribosomal RNA genes, 22 transfer RNAs, and a single control region

Plant Virus‐Induced Inheritable Apoptosis Drives Reproductive Costs in Female Insect Vectors to Balance Viral Biparental Transmission

open access: yesAdvanced Science, Volume 13, Issue 5, 27 January 2026.
Rice gall dwarf virus (RGDV), transmitted biparentally by leafhopper vector to their offspring, exploits the capsid protein to induce inheritable ovarian apoptosis via insulin‐driven PI3K/AKT/FoxO signaling axis. This mechanism enhances infection but reduces female reproductive fitness, causing inefficient maternal transmission.

Transovarial transmission of a plant virus is mediated by vitellogenin of its insect vector. [PDF]

open access: yesPLoS Pathogens, 2014
Most plant viruses are transmitted by hemipteroid insects. Some viruses can be transmitted from female parent to offspring usually through eggs, but the mechanism of this transovarial transmission remains unclear.

Susceptibility of Several Insecticides on Three Aphids [PDF]

open access: yes, 1987
Differences in susceptibility of several organophosphate, carbamate and pyrethroid insecticides to three aphids species were determined by leaf-dipping and spray methods.

Insect I‐Type Lysozymes Function as Antiviral Proteases by Forming Biomolecular Condensates

open access: yesAdvanced Science, Volume 13, Issue 1, 5 January 2026.
Upon rice viral infection, the insect vector activates the Toll–MyD88–Dorsal signaling cascade, inducing i‐type lysozyme (Lyz‐I1) expression. Lyz‐I1 functions as an antiviral protease through its conserved catalytic dyad Glu/Asp (E/D), mediating cleavage of viral proteins at specific Lys (K) residues.

Isolation of Rice Stripe Virus Preparation from Viruliferous Small Brown Planthoppers and Mechanic Inoculation on Rice

open access: yesBio-Protocol, 2017
Tenuiviruses can infect the plants of the family Poaceae, and cause serious loss of crops, particularly rice and maize, in South-Eastern Asian countries.
