RELATIVE TOXICITY OF TRIAZOPHOS TO S. FURCIFERA The sensitivity of the 3rd instar nymphs and adults was determined for each rice stem impregnation method, and detailed results are shown in Table 1. Based on this method and 5 replications, the LC50, LC25, and LC10 values of triazophos to 3rd instars 72 h afer treatment were 13.63, 5.86, and 2.74 mg [AI]

Differential DNA methylation between two wing phenotypes adults of Sogatella furcifera
genesis, 2013SummarySogatella furcifera is a major rice pest with wing dimorphism. DNA methylation is an important epigenetic modification that plays a role in gene regulation and phenotype variation in most organisms. The objective of the current research was to survey the frequencies and variation of cytosine methylation at CCGG sequences in macropterous female ...

Biology and lifetable of whitebacked planthopper Sogatella furcifera (Horvath) on rice
Indian Journal of Entomology, 2022Whitebacked planthopper Sogatella furcifera (Horvath) is an important insect pest causing economic damage to rice. Studies on its biology in West Bengal revealed that the fecundity was 197± 13.37 eggs/ female. The incubation period was 7.6± 0.69 days in October, with nymphal duration being 16.2± 0.85 days; and longevity of male macropterous ones was 9 ...

ECOLOGY OF THE WHITE BACKED PLANTHOPPER, Sogatella furcifera IN RICE
Madras Agricultural Journal, 1996Field populations of S. furcifera (Horvath) at Coimbatore was generally very low and there was not much difference in the population level between the cultivars, Jaya and IR 36. Crops sown in the months of August to November harboured more hoppers. The population caught in the light traps was high during 1979-80 and very low during 1981-82.

AbstractSogatella furcifera (Hovarth) is a major rice pest with sexual dimorphism. The objective of the current research was to monitor differentially cytosine methylation at CCGG sequences in male and female adults of S. furcifera to determine the association between gene methylation and sexual phenotypes using methylation‐sensitive representational ...

Chitinase is used to degrade chitin in insect cuticles and the peritrophic matrix. In this study, the full-length cDNA sequence of a Cht gene (SfCht7) was identified and characterized from the white-black planthopper, Sogatella furcifera. The SfCht7 cDNA was 3148bp, contained an open reading frame of 2877bp and encoded 958 amino acids with a predicted ...

Effect of temperature on rice white backed plant hopper Sogatella furcifera
Indian Journal of Entomology, 2018Influence of variable temperature combinations viz. 32 & 22°C, 32 & 24°C, 32 & 26°C, 35 & 22°C, 35 & 24°C and 35 & 26°C (maximum & minimum) maintained for 12: 12 hours, on developmental and reproductive physiology of the white backed plant hopper, Sogatella furcifera (Horvath), a serious sucking insect pest of rice in Punjab was studied.

[Adaptation of Sogatella furcifera to insect-resistant rice variety N22].
Ying yong sheng tai xue bao = The journal of applied ecology, 2004The adaptation of whitebacked planthopper (WBPH) Sogatella furcifera to insect-resistant rice variety N22 and the variation of its protective enzyme were studied by rearing it successively two generations on N22 and insect-susceptible rice variety TN1 in laboratory.

The diamide insecticides activate ryanodine receptors (RyRs) to release and deplete intracellular calcium stores from the sarcoplasmic reticulum of muscles and the endoplasmic reticulum of many types of cells. They rapidly interrupt feeding of the target pest and eventually kill the pest due to starvation.
