“…The results revealed that the knockdown rate for an AC concentration of 200 ppm was 83.6%, and the insecticidal LD50 was 22.68 ng/pest. Furthermore, AC may be neurotoxic to the brown planthopper, and the conscious nymphs are resistant to drug neurotoxicity by upregulating CYP3A4, UGT, and GABA receptor mutations [68]. The gut microbiota played an important role in pheromone production, pesticide degradation, vitamin synthesis, and pathogen prevention in the host animal.…”

Aconitum alkaloids are considered to be the characteristic bioactive ingredients of Aconitum species, which are widely applied to the treatment of diverse diseases, and aconitine (AC) is found in most Aconitum plants.Research evidence shows that low-dose AC has a good therapeutic potential in heart failure, myocardial infarction, neuroinflammatory diseases, rheumatic diseases, and tumors, which has become one of the hotspots in global research in recent years. However, the cardiotoxicity and neurotoxicity of AC have also attracted extensive attention. Excessive use of AC always induces ventricular tachyarrhythmia and heart arrest, even can be potentially lethal. Therefore, AC cannot simply be regarded as a good medicine or a toxicant, but its underlying curative and toxic properties remained chaos. In order to dig the unique pharmacological value of AC while preventing its toxicity, the pharmacological activities and toxic effects of AC were summarized in this paper, providing new insight into the safe and effective use of AC in clinical practice.

“…The brown planthopper (BPH), Nilaparvata lugens (St å l) (Hemiptera: Delphacidae), is one of the economically important insect pests identified in this crop, having an international significance ( Normile, 2008 ; Heong & Hardy, 2009 ). This phloem sap feeder transmits rice ragged stunt virus (RRSV) and rice grassy stunt virus (RGSV), and holds the ability to cause more than 60% economic yield loss under favourable environmental conditions throughout Asia ( Kumar, Maurya & Tiwari, 2012 ; Wei et al, 2019 ). Several chemical insecticides are registered to control rice BPH, but the unscientific and injudicious application of those products breaks the natural pest defender ratio in the field ( Sarao & Mangat, 2014 ; Roy & Chakraborty, 2022 ).…”

Evaluation and identification of resistant donors for brown planthopper (BPH) Nilaparvata lugens (Stål.), an economically important insect pest of rice, is a continuous process to develop new resistant rice varieties. However, several rice landraces of north-eastern India are not yet characterized for BPH resistance. In the present study, a set of 218 rice landraces were screened in both greenhouse and open-field conditions for three consecutive years, and thereafter forty selected promising entries were explored to evaluate their phenotypic and genotypic reactions against BPH biotype 4. Based on phenotypic evaluations, five landraces were identified as resistant, while 31 were moderately resistant, and grouped under the major cluster I and II, respectively, in a circular dendrogram. Antixenosis and antibiosis studies of these landraces divulged that, compared to the susceptible check variety, resistant landraces exhibited the lowest feeding rate, survival, and nymphal and adult settling, but higher frequency of unhatched eggs of BPH. Un-infested resistant landraces registered higher levels of ascorbic acid, oxalic acid and crude silica, however, elevated levels of total free amino acid, potassium and crude silica were observed under BPH herbivory. The present study focuses on identifying new donors having BPH resistance resources which could be useful in genomic studies for the development of BPH biotype 4 resistant rice varieties.

“…Of over twenty insects species recognized as economically important pests of this crop, the brown planthopper (BPH), Nilaparvata lugens (Stål) (Homoptera: Delphacidae) is one of them (Normile 2008;Heong and Hardy 2009). This phloem sap feeder is known to be one of the most destructive and notorious pests of rice throughout Asia and hold the ability to create as high as 60% yield loss under epidemic conditions (Kumar et al 2012;Wei et al 2019). Host-plant resistance to insect injury occurs in plants that use strategies to recover, tolerate or avoid from the attack of pest (Smith 2005); thus, plant characteristics that have negative influences on insect-pest biology, reproduction and development could be used in the screening of plants resistant to insect (Rekha and Singh 2001).…”

Brown planthopper (BPH), [Nilaparvata lugens (Stål.)] is an economically important pest of rice (Oryza sativa L.) throughout Asia, where the damage caused by nymphs and adults, especially during post-tillering to milking stages, significantly reduces grain yield. There is, thus, a pressing need to develop varieties that are resistant to BPH. In this study, the reaction of various rice landraces from Indian origin were assessed (both phenotypically and biochemically) in response to BPH infestation. It was found that the landraces, viz. Badshabhog, Gamra, Haldichuri, Janglijata, Kalabhat, Khara, Adanshilpa, Chikonmashuri, Kerala sundari and Lal dudheshwar exhibited resistance to BPH consistently along with the standard check Ptb33, for three consecutive years under both greenhouse and open-field conditions. These phenotypically resistant rice landraces including Ptb33 exhibited lowest feeding rate, least nymphal and adult preference, minimum survival and higher frequency (%) of unhatched eggs when compared with the susceptible check (Swarna). Higher levels ascorbic acid, oxalic acid (OA), crude silica (CS), while lower levels of phenols, reducing sugar and total free amino acid (TFA) were expressed in un-infested resistant and moderately resistant landraces. The resistant plants exposed to herbivory by BPH produced higher levels of phenolic compounds, potassium and TFA than plants of susceptible cultivar Swarna. The feeding rate, settling behaviour and survivability of BPH correlated significantly and negatively with OA and CS, whereas the latter showed a significant and positive correlation with egg hatchability.
