Knockdown of Methoprene-Tolerant Arrests Ovarian Development in the Sogatella furcifera (Hemiptera: Delphacidae) [PDF]

open access: yesJournal of Insect Science, 2019
AbstractJuvenile hormone (JH) is responsible for repressing larval metamorphosis and inducing vitellogenesis and egg production in insects. Methoprene-tolerant (Met) is known to be an intracellular receptor and transducer of JH. We examined the role of Met in ovarian development in the rice pest Sogatella furcifera (Horváth).

Controlling sap-sucking insect pests with recombinant endophytes expressing plant lectin [PDF]

open access: yes, 2010
We developed a novel pest management strategy, which uses endophytes to express anti-pest plant lectins. Fungal endophyte of Chaetomium globosum YY-11 with anti-fungi activities was isolated from rape seedlings, and bacterial endophytes of SJ-10 ...

LsFAMeT and LsJHAMT coordinate JH biosynthesis to regulate fecundity in Laodelphax striatellus

open access: yesInsect Science, EarlyView.
The small brown planthopper (SBPH), Laodelphax striatellus, can trigger large‐scale outbreaks when encountering suitable habitats during migration due to their strong reproductive ability. This study investigated the role of juvenile hormone (JH) in regulating SBPH reproduction.

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.

The Transcription Factor OsWRKY64 Interacts With OsART1 to Positively Regulate Al Resistance in Rice

open access: yesPlant Biotechnology Journal, EarlyView.
A proposed working model illustrating the cooperative regulation of Al tolerance by OsWRKY64 and OsART1 in rice. Under Al stress conditions in acidic soil, the transcription factor OsART1 directly binds to the promoter of OsWRKY64 to activate its transcription. The synthesized OsWRKY64 protein then physically interacts with OsART1 in the nucleus.
