TL;DR: Species and stage specific differences in the susceptibility of the mosquitoes to the active fractions of the plant extracts were observed and I and II instar larvae were more susceptible to theactive fractions.
Abstract: Larvicidal activity of partially purified extracts of leaves of Vitex negundo, Nerium oleander and seeds of Syzygium jambolanum on different instars of Culex quinquefasciatus and Anopheles stephensi was estimated. Petroleum ether (PE): Ethyl acetate (EA) 3:1 fraction of V. negundo, 1:1 fractions of N. oleander and S. jambolanum inflicted considerable larval mortality and interfered with pupal-adult metamorphosis. At very low concentration the active fractions of these plant extracts extended the duration of the various larval instars and of pupation. In general, I and II instar larvae were more susceptible to the active fractions. Species and stage specific differences in the susceptibility of the mosquitoes to the active fractions of the plant extracts were observed.

TL;DR: In this article, a field study was carried out to determine the relative efficacy of repellant action of vegetable, essential and chemical base oils against vector mosquitoes against Anopheles culicifacies and other anopheline species.
Abstract: Field studies were carried out to determine the relative efficacy of repellant action of vegetable, essential and chemical base oils against vector mosquitoes. Results revealed that essential oils viz. Cymbopogan martinii martinii var. Sofia (palmarosa), Cymbopogan citratus (lemon grass) and Cymbopogan nardus (citronella) oils are as effective as chemical base oil namely mylol. These oils provide almost complete protection against Anopheles culicifacies and other anopheline species. Per cent protection against Culex quinquefasciatus ranged between 95-96%. Camphor (C. camphora) oil also showed repellent action and provided 97.6% protection against An. culicifacies and 80.7% against Cx. quinquefasciatus. Vegetable oils namely mustard (B. compestris) and coconut (C. nucisera) showed repellent action, however the efficacy of these oils was not much pronounced against Cx. quinquefasciatus. Results of statistical analysis revealed significant difference between vegetable and essential oils (p < 0.01) against tested species of mosquitoes. Essential oils were found marginally superior in repellancy than camphor and mylol (p < 0.01) against An. culicifacies and Cx. quinquefasciatus.

TL;DR: It was showed that vivax malaria can present with atypical and protean manifestations and the changing clinical profile along with development of chloroquine resistance may be considered as a warning signal.
Abstract: About 110 patients were enrolled to study the atypical presentations and the chloroquine sensitivity pattern of Plasmodium vivax malaria. The diagnosis was made from Giemsa stained peripheral blood smear. The co-infection of falciparum malaria was excluded both by smear and ParaSight F-test. After a thorough clinical work up, biochemical investigations were done. The fever clearance and parasite clearance time were determined in all cases. Absence of malarial paroxysm (22.8 per cent), migrainous headache (4.5 per cent), myalgia (6.3 per cent), episodic urticarial rash (1.8 per cent), relative bradycardia (13.6 per cent) and postural hypotension (2.7 per cent) were the atypical manifestations encountered. Besides this, severe forms like jaundice (7.2 per cent), cerebral involvement (0.9 per cent), severe anaemia (7.2 per cent), thrombocytopenia (3.6 per cent) and pancytopenia (0.9 per cent) had been detected. All, except the patient with cerebral involvement were treated with chloroquine patients responded well to the treatment except two (1.8 per cent) patients who had chloroquine resistance. This study showed that vivax malaria can present with atypical and protean manifestations. The changing clinical profile along with development of chloroquine resistance may be considered as a warning signal.

TL;DR: A field study was carried out to evaluate the mosquito repellent action of neem (Azadirachta indica) oil in tribal forested villages of District Mandla and revealed 81-91% protection from the bites of anopheline mosquitoes.
Abstract: A field study was carried out to evaluate the mosquito repellent action of neem (Azadirachta indica) oil in tribal forested villages of District Mandla. Various concentrations of neem oil mixed in coconut oil (1-4%) were applied to the exposed body parts of human volunteers. Results revealed 81-91% protection during 12 h period of observation from the bites of anopheline mosquitoes. Neem oil is an indigenous product and a practical solution to curtail mosquito nuisance.
