In recent years, significant research has focused on the synthesis of novel green nanoparticles for mosquito control purposes. Metallic green nanoparticles (NPs) have demonstrated their effectiveness in combating mosquitoes, but our understanding of these nano molecules remains incomplete. This book chapter provides a comprehensive review of the ex...

Experiments were conducted to investigate the antifeedant activity of leaf extracts of Wrightia tinctoria, Murraya koenigii, and Prosopis juliflora against teak leaf skeletonizer, Eutectona machaeralis Walk. The study was carried out from August 2021 to July 2022 in the Zoology laboratory of Tara Government Degree and PG College, Sangareddy (latitu...

Larvae of the citrus butterfly, Papilio demoleus are serious pests in citrus orchards. Since synthetic pesticides have several ill effects on human health and the ecosystem, biopesticides are feasible alternative to synthetic pesticides. Indian beech tree, Pongamia pinnata plant extracts are well known for their medicinal and pesticidal properties....

Aedes vittatus (Bigot) mosquitoes, known to breed in diverse habitats, have been identified in Corsica, Europe, and have a geographical distribution across tropical Asia, Africa, and the Mediterranean region of Europe. These mosquitoes are potential vectors of arboviruses such as yellow fever, dengue, chikungunya, and Zika, raising concerns about p...

This study conducted at Tara Government College (Autonomous) in Sangareddy, Telangana, aimed to establish a baseline for butterfly diversity. The campus, spread over approximately 20 acres, hosts a diverse range of plant species, including Mangifera indica, Ficus bengalensis, Azadirachta indica, and others. Field observations were conducted from De...

The global spread of Aedes albopictus, known as the Asian tiger mosquito, to 86 new countries has raised concerns about vector-borne disease transmission. The dispersal of these mosquitoes is facilitated by international trade and climate change. Effective vector control strategies and international cooperation are essential to mitigate the risk of...

Mosquitoes are notorious vectors of severe diseases, posing significant threats to human health. Although pesticides are commonly used for mosquito control, their indiscriminate application can harm the environment and non-target organisms. Consequently, alternative strategies, such as plant-based mosquitocides, are gaining interest. This study eva...

Among all insects, butterflies are the most recognisable and well-known. Lepidoptera is the name of the order that includes butterflies. In addition to being excellent indicators of climate change, butterflies significantly contribute to highlighting the astounding diversity of nature. Additionally, studying butterfly wing patterns offers a chance...

The brinjal shoot and fruit borer, scientifically known as Leucinodes orbonalis Guenee, is a major insect pest that causes significant damage to eggplant crops in the Indian subcontinent. The use of synthetic pesticides to control this pest has raised concerns due to their negative impact on the environment and human health. Consequently, there is...

Rice (Oryza sativa Linn.) is a vital cereal crop and a staple food for a significant portion of the global population. However, the rice weevil (Sitophilus oryzae) poses a serious threat to rice storage, causing substantial losses and impacting food availability. The current methods of controlling rice weevils primarily rely on the use of chemical...

Pongamia pinnata aqueous leaf extracts (PALE) and P.pinnata synthesized Zinc Oxide nanoparticles synthesized (Pp-ZnONPs) efficacy as antifeedants against the 4 th instar larvae of Citrus butterfly, Papilio demoleus L. was evaluated in this study conducted between July 2022 and November 2022.
