An annotated list of planthoppers with alternate hosts from Kallar tract of Punjab, Pakistan [PDF]

, 2020
Diversity of planthoppers and their host plants were studied in the "Kallar" tract of the Punjab, Pakistan (an important growing area of the world for producing Basmati rice). Planthoppers are considered the most important pests of rice.

Effects of elevated CO2 on feeding responses of biological control agents of Pontederia crassipes

Entomologia Experimentalis et Applicata, Volume 171, Issue 12, Page 998-1008, December 2023., 2023
Studies have shown that elevated CO2 will affect insect feeding guilds differently. Water hyacinth plants, Pontederia crassipes (Pontederiaceae), were grown under two CO2 concentrations (400 and 800 p.p.m.), with and without two biocontrol agents representing different feeding guilds, the leaf‐chewing Cornops aquaticum (Orthoptera: Acrididae) and the ...

Knockout of cryptochrome 1 disturbs the locomotor circadian rhythm and development of Plutella xylostella

Insect Science, Volume 30, Issue 4, Page 1035-1045, August 2023., 2023
The cry1‐knockout strain (Cry1‐KO) of Plutella xylostella was developed by using the CRISPR/Cas9 system. No daily temporal oscillation of cry1 was observed in Geneva 88 (G88) and Cry1‐KO, and cry1 mean daily transcription of Cry1‐KO was lower than that of G88.

Bacterial Symbionts of the Brown Planthopper,Nilaparvata lugens(Homoptera: Delphacidae) [PDF]

Applied and Environmental Microbiology, 2010
ABSTRACTThe brown planthopper (Nilaparvata lugensStål), the most destructive pest of rice, has been identified, including biotypes with high virulence towards previously resistant rice varieties. There have also been many reports of a yeast-like symbiont ofN. lugens, but little is known about the bacterial microbes.

Pest risk assessment of Elasmopalpus lignosellus for the European Union

EFSA Journal, Volume 21, Issue 5, May 2023., 2023
Abstract Following a request from the European Commission, the EFSA Panel on Plant Health performed a quantitative pest risk assessment of Elasmopalpus lignosellus (Lepidoptera: Pyralidae), the lesser cornstalk borer, for the EU. The assessment considered entry, establishment, spread and impact.

Communal rearing induces high predatory capacity in a solitary wolf spider and its potential in pest control

Ecology and Evolution, Volume 13, Issue 4, April 2023., 2023
Pardosa pseudoannulata is a solitary wolf spider and it is a major predator of pests such as Nilaparvata lugens in rice fields. The results showed that the survival rates of the communal‐reared and individual‐reared spiders were similar, but communal‐reared spiders were significantly more voracious.

Stemborer‐induced rice plant volatiles boost direct and indirect resistance in neighboring plants

New Phytologist, Volume 237, Issue 6, Page 2375-2387, March 2023., 2023
Summary Herbivore‐induced plant volatiles (HIPVs) are known to be perceived by neighboring plants, resulting in induction or priming of chemical defenses. There is little information on the defense responses that are triggered by these plant–plant interactions, and the phenomenon has rarely been studied in rice. Using chemical and molecular analyses in

Abundance and species richness of leafhoppers and planthoppers (Hemiptera: Cicadellidae and Delphacidae) in Brazilian maize crops. [PDF]

, 2018
Insects in the Cicadellidae and Delphacidae families, common in grasses, are an important group of vectors of viruses and mollicutes, which cause diseases in several plant species. The goal of this study was to evaluate the abundance and species richness
