The greenhouse whitefly Trialeurodes vaporariorum Westwood is one of the most important economic pests of greenhouse products around the world. The use of pesticides is one of the most common methods to control this pest. The wide distribution of the host, the large number of generations, and the polyphagous nature of T.

Background: Synergists reduce insecticide metabolism in mosquitoes by competing with insecticides for the active sites of metabolic enzymes, such as cytochrome P450s (CYPs). This increases the availability of the insecticide at its specific target site. The combination of both insecticides and synergists increases the toxicity of the mixture.

Perfluorononanoic acid (PFNA), widely employed in surfactants, coatings, plastics, corrosion inhibitors, and fire-extinguishing agents, is less regulated than PFOS or PFOA but displays higher bioaccumulation and potential toxicity. Most toxicity assessments have focused on mammals, fish, and algae, with limited research on ground-dwelling arthropods, especially ants. Here, we examined PFNA's toxic effects on red imported fire ants (RIFAs), a prevalent ground-dwelling species in South China.

Objective: To investigate the physiological characteristics of subspecies (Bti) with double mutations of and genes and to assess the activity of Bti against larvae of under different external factors, so as to provide the theoretical evidence for the use of engineered bacteria of Bti for effective mosquito control.
Methods: wild-type strain Bt-59 and Bt-59 strain with mutation [Bt-59 (Δ)] were cultured in nutrient broth media for 24 hours, and Bt-59 strains with mutation [Bt-59 (Δ)] and double mutations of and [Bt-59 (Δ)] were cultured in nutrient broth media for 48 hours. Then, 5 μL of culture media were transferred to glass sides, and cell morphology and mother cell lysis were observed under an optical microscope.

European honey bee (Apis mellifera) colonies are an ideal host to the invasive beetle Aethina tumida, providing a nutrient rich environment that is protected from the elements and facilitates beetle reproduction. Although various management techniques and chemical treatments for A. tumida have been developed, understanding the efficacy of these treatments and techniques is limited.
