Effects of plant latex based anti-termite formulations on Indian white termite <i>Odontotermes obesus</i> (Isoptera: Odontotermitidae) in sub-tropical high infestation areas

“…In addition, latex based formulations have shown deleterious effects on insects like anti-feedant, growth and reproductive inhibitory activities [7]. In the previous studies C. procera latex also showed toxic effects against Culex quinquefasciatus [11], Sarcophaga haemorrhoidalis [12] and Musca domestica [13,23], Anopheles stephensi [24] and showed inhibition of gonotrophic cycles [4], oviposition [25], egg hatching and larval development in Aedes aegypti [15]. Similarly, latexes from Euphorbia spledens var.…”

“…Due to their longer residual persistence in the environment, these were proved highly toxic to non-target organisms in the ecosystem. Hence, new alternatives of synthetic pesticides were discovered in form of natural pesticides which display low toxicity to humans and the environment, having low costs among other advantages [4].…”

Secondary metabolites, antimicrobial, brine shrimp lethality & 4 th instar Culex quinquefasciatus mosquito larvicidal screening of organic & inorganic root extracts of Microcos paniculata.

“…Filariasis is an endemic, disabling, disfiguring disease and the filarial worm, Wuchereria bancrofti responsible for human filariasis is carried by Culex quinquefasciatus Say (Diptera: Culicidae), a pantropical pest and urban vector of Wuchereria bancrofti [9] and is probably the most abundant house mosquito in towns and cities of the tropical countries [10]. Plant products have been used traditionally by human communities [11] and application of easily degradable plant compounds is considered to be one of the safest methods of control of insect pests and vectors [12].…”

Ovicidal and repellent activities of botanical extracts against Culex quinquefasciatus, Aedes aegypti and Anopheles stephensi (Diptera: Culicidae)

“…They are active against a limited number of species including specific target insects, and are bio-degradable. They are potentially suitable for use in integrated pest management programs [4] . The leaf and seed extract of plant Agave americana [5] had mosquito larvicidal properties, and the extract of Tagetes minuta flowers had mosquito larvicidal activity against Aedes aegypti (Ae.…”
