“…For toxicological and ecotoxicological risk assessment, a mixture of a fertilizer and an insecticide is to be considered as a new molecule with its own toxic properties 10 . Mixtures with the most interesting fertilizer and insecticidal activities on aphid pest and mosquitoes must meet benefit/risk requirements and show what benefit the mixture may bring within the framework of a specific control action.…”

BACKGROUND: A great number of areas favourable for the proliferation of mosquitoes are found in farmland, the most favourable being market gardens and rice paddies. The only means of limiting crop pests (AGRI) and mosquito vectors of human pathogens (AC = antivectorial control) in agricultural environments consists of incorporating systemic or translaminar insecticides into fertilizers (AGRIAC). The plant used in this study was the chili pepper (Capsicum chinensis). Experiments were carried out with Myzus persicae aphid pests and Aedes albopictus mosquitoes. Fertilizers were applied in association with thiacloprid, cyromazine, azadirachtin and Bacillus thuringiensis var. israelensis (Bti) + Bacillus sphaericus (Bs) insecticides. Chili pepper seedlings were dried to assess the amount of insecticide in their tissues. RESULTS: NPK + thiacloprid and NPK + azadirachtin remained efficient against aphids for 28 days, whereas Bti + Bs had to be added to both mixtures to make them efficient against Ae. albopictus larvae. NPK + cyromazine remained active against both aphids and mosquitoes for 15 days. The search for insecticide residues in chili pepper showed that untreated plants displayed natural toxicity to Ae. albopictus larvae. The toxic effects induced by the capsaicinoid compounds inside the plant add up to the insecticide action of thiacloprid, cyromazine and azadiractin.CONCLUSION: The AGRIAC concept allows for an innovative vector control method that can manage aphid pests and mosquitoes while providing plants with the needed fertilizer.

“…Domestic host breeding sites, such earthenware vases, barrels, cisterns, gutters, cans, tyres and plant saucers, are the main targets for the control. For example, the presence of fertilizers (e.g., NPK) in the water of plant saucers is considered a possible attractant for gravid females [ 4 ]. Therefore, the development of alternative larvicides, such those from natural origin, for domestic use should be encouraged.…”

Baccharis reticularia DC. and Limonene Nanoemulsions: Promising Larvicidal Agents for Aedes aegypti (Diptera: Culicidae) Control

et al. 2017

Baccharis reticularia DC. is a plant species from the Asteraceae family that is endemic to Brazil. Despite the great importance of Baccharis genus, no study has been carried out regarding either the phytochemical composition of B. reticularia or the evaluation of its larvicidal potential. Considering the intrinsic immiscibility of essential oils, this study shows larvicidal nanoemulsions containing the B. reticularia phytochemically characterized essential oil and its main constituent against Aedes aegypti. The major compound found was d-limonene (25.7%). The essential oil inhibited the acetylcholinesterase, one of the main targets of insecticides. The required hydrophile-lipophile balance of both nanoemulsions was 15.0. The mean droplet sizes were around 90.0 nm, and no major alterations were observed after 24 h of preparation for both formulations. After 48 h of treatment, the estimated LC50 values were 118.94 μg mL−1 and 81.19 μg mL−1 for B. reticularia essential oil and d-limonene nanoemulsions, respectively. Morphological alterations evidenced by scanning electron micrography were observed on the larvae treated with the d-limonene nanoemulsion. This paper demonstrated a simple and ecofriendly method for obtaining B. reticularia essential oil and d-limonene aqueous nanoemulsions by a non-heating and solvent-free method, as promising alternatives for Aedes aegypti control.

“…Furthermore, some possible mechanism was involved to release various toxic metabolites or certain free radicals from the fertilizers since fertilizers are the potent generator of free radicals which were responsible for blocking the active metabolic process of egg hatching and their subsequent development [ 39 ]. Urea, potash, N-P-K fertilizer hindered hatching, larval development and survival of Aedes aegypti by alteration of pH, interruption in nervous transmission, conductivity, and total dissolved solid of parasitic developmental stages [ 40 , 41 ].…”

Aim:The effects of N-P-K fertilizers in the form of urea, single super phosphate and muriate of potash on development of free-living stages of Haemonchus contortus were studied.Materials and Methods:Five parasite free experimental plots of 1 m×1 m area, each of paddy leaves (15-day-old) and an equal number of Cynodon dactylon grass were infested with about 10×104 eggs/ml phosphate buffer saline along with the application of the calculated amount of fertilizers solution. On the 10th day of posttreatment, the pasture was cut, processed, larvae recovered by Baermann method and counted, which was expressed as number of L3 per kg dry matter (DM) of pasture.Results:The average recovered population of L3 of H. contortus per kg DM varied significantly (p<0.05) between the paddy leaves (5933.57±22.718) and Cynodon grass (4861.00±22.718). When different doses of chemical fertilizer and their impact on different pasture were analyzed for control (T-1, 0-0-0 kg/ha N-P-K), the mean L3 recovery per kg DM of paddy (19512.7±50.80) was more than that of Cynodon grass (16540.9±50.80). Larvae recovery per kg DM for different pastures under treatment were in decreasing order as follows: T-2 of paddy (6981.33±50.80, 35.77%), T-2 of Cynodon (5545.38±50.80, 33.52%), T-3 of paddy (317378±50.80, 16.26%), and T-3 of Cynodon (2218.72±50.80, 13.41%) which showed significant difference (p<0.05) among the treatments. In T-4 (paddy) and T-5 (Cynodon), the average number of recovery of larvae was nil implying no significant variation (p>0.05).Conclusion:This study shown that when N-P-K fertilizers administered at recommended level, significantly reduced larval translation of H. contortus minimizing pasture infectivity for the free range grazing animals.
