A compartmental model is developed, in the form of a nonautonomous system of delay differential equations subject to impulses at specific times, for mosquito-born disease control involving larvicides and insecticide sprays. Sufficient conditions in terms of the frequencies and rates of larvicides and insecticide sprays are derived, and numerical simulations are provided to illustrate the sharpness of these disease eradication conditions.

A series of novel triazone derivatives containing aldehyde hydrazone or ketone hydrazone moieties were designed, synthesized and their biological activities were investigated against , , , , and 14 Kinds of fungi. Most of the aldehyde hydrazone exhibited excellent insecticidal activities against . In particular, the aphicidal activities of compounds (35%) and (30%) were equivalent to pymetrozine (30%) at 5 mg/kg.

Background: Owing to their extensive utilization as pesticides, heterocycles assume a fundamental role in the management of vector-borne diseases. Despite the presence of numerous heterocyclic compounds in commercial insecticides and larvicides, resistance to pesticides still demands novel strategies to current pest control methods. Considering these facts, this review aims to survey the synthesis and SAR of heterocyclic molecules with larvicidal activity against Aedes aegypti Linn.

Background: , a malaria mosquito originally from South Asia and the Middle East, has been expanding across both Asia and Africa in recent decades. The invasion of this species into sub-Saharan Africa is of particular concern given its potential to increase malaria burden, especially in urban environments where thrives. Whilst surveillance of this vector in Africa has recently increased markedly there is a need to review the existing methods of control so that we can stop, rather than simply monitor, its spread in Africa.

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.
