Insecticidal Activities of Fresen Extracts and Feeding Behavior of Rondani: Electropenetrography Approach.

The aphid, Rondani (Hemiptera: Aphididae), is one of the most destructive pests of wheat. It is responsible for significant economic losses in the agricultural sector, with an estimated 45% of wheat fields affected. Plant-based insecticides have seen a rapid increase in popularity in recent years due to their efficacy, cost-effectiveness, biodegradability, and lower toxicity compared to synthetic pesticides.

Buffalo-bur (S Dunal) invasiveness, bioactivities, and utilization: a review.

Dunal, belongs to the Solanaceae family and has drawn attention for its intricate interplay of invasiveness, phytochemical composition, and potential bioactivities. Notably invasive, employs adaptive mechanisms during senescence, featuring thorn formation on leaves, fruits, and stems seed self-propulsion, and resistance to drought. This adaptability has led to its proliferation in countries such as China, Canada, and Australia, extending beyond its Mexican origin.

Volatile Signals From Guava Plants Prime Defense Signaling and Increase Jasmonate-Dependent Herbivore Resistance in Neighboring Citrus Plants.

Intercropping can reduce agricultural pest incidence and represents an important sustainable alternative to conventional pest control methods. Citrus intercropped with guava ( L.) has a lower incidence of Asian citrus psyllid (ACP, Kuwayama) and huanglongbing disease (HLB), but the mechanisms are still unknown.

Two Alkaloids From Royle, Their Anti-inflammatory and Anti-oxidative Stress Activity NF-κB Signaling Pathway.

In this study, we isolated and identified four compounds in Royle, and they were Delbrunine (), 4--α-D-Glucosyl benzoic acid (), Kaempferol 3--β-D-glucopyranoside 7--α-L-rhamnopyranoside () and Eldeline (). Furthermore, the anti-inflammatory activity of these compounds was screened in RAW264.7 cells.

Latest Developments in Insect Sex Pheromone Research and Its Application in Agricultural Pest Management.

Since the first identification of the silkworm moth sex pheromone in 1959, significant research has been reported on identifying and unravelling the sex pheromone mechanisms of hundreds of insect species. In the past two decades, the number of research studies on new insect pheromones, pheromone biosynthesis, mode of action, peripheral olfactory and neural mechanisms, and their practical applications in Integrated Pest Management has increased dramatically. An interdisciplinary approach that uses the advances and new techniques in analytical chemistry, chemical ecology, neurophysiology, genetics, and evolutionary and molecular biology has helped us to better understand the pheromone perception mechanisms and its practical application in agricultural pest management.

Seriphidium brevifolium essential oil: a novel alternative to synthetic insecticides against the dengue vector Aedes albopictus.

The Aedes albopictus mosquito is a vector of several deadly diseases of humans and domesticated animals. Usually, synthetic insecticides are used for mosquito control. The excessive use of synthetic insecticides is hazardous for humans and the environment.

Larvicidal, Ovicidal, Synergistic, and Repellent Activities of and Its Dominant Constituents Against .

In the current study, to combat insecticide resistance, we explored larvicidal, ovicidal, synergistic, and repellent activities of extract and its dominant constituents against . The results of the toxicity bioassays demonstrated that the extract of exerted significant larvicidal activity (16.66-86.

Evaluating the repellent effect of four botanicals against two species on mangoes.

Background: and are economically important fruit fly pests of crops, vegetables, fruits, and nuts worldwide, especially in China. Nowadays in China, is a second notorious pest of many fruits after . Different botanicals have been tested against the but in the case of , no records were published.

Differences in susceptibility to insecticides among color morphs of the Asian citrus psyllid.

Insect color morphs are known to vary in detoxification enzyme activity associated with susceptibility to insecticides. Diaphorina citri occurs in three distinct color morphs, and little data are available addressing this question. In this study, susceptibility to nine insecticides was compared among orange/yellow, gray/brown and blue/green morphs of adult D.

Development and evaluation of emulsifiable concentrate formulation containing Sophora alopecuroides L. extract for the novel management of Asian citrus psyllid.

Utilization of non-host plants semiochemicals to mediate insect behavior offers a promising opportunity for novel management of insect pests in field crops and fruits. Therefore, there is still a substantial opportunity for the development of natural prophylactic as an eco-friendly approach in the novel pest management programs. Sophora alopecuroides extract has been used as a natural pesticide in the control of agricultural and household pests, but the low persistence effect and rapid biodegradability limit its use on a wider scale in pest management programs.

Interference mechanism of Sophora alopecuroides L. alkaloids extract on host finding and selection of the Asian citrus psyllid Diaphorina citri Kuwayama (Hemiptera: Psyllidae).

Manipulating insect behavior through the deployment of semiochemicals offers a promising opportunity for protecting crops in a sustainable manner. Therefore, there is still a significant opportunity for the development of natural crop protectants as eco-friendly tools in pest management. In this context, the aim of the current investigation is to find a novel prophylactic against the Asian citrus psyllid (ACP) and to gain a better understanding of the host-finding and selection ability of the ACP towards Murraya paniculata seedlings treated with Sophora alopecuroides alkaloids extract (SAAE).

Detection and biochemical characterization of insecticide resistance in field populations of Asian citrus psyllid in Guangdong of China.

The Asian citrus psyllid, Diaphorina citri Kuwayama, is one of the most damaging pests of citrus-producing regions throughout the world. The use of insecticides is the main strategy for controlling psyllid and has increased year by year. In this study, four field populations of D.
