“…In field applications, tephrosia aqueous extracts have been used successfully to control coleopteran pests (Alao and Adebayo 2015;Mkenda et al 2015a;Tembo et al 2018), dipteran pests (Alao and Adebayo 2015), hemipteran pest (Mkenda et al 2015a;Tembo et al 2018), and lepidopteran pests (Olaitan and Abiodun 2011) ( Table 1). In comparison with positive controls, the efficacy was often similar or inferior (3 instances each), but was superior in 1 instance (Table 2).…”

Homemade botanical insecticides are widely used by subsistence and transitional farmers in low-income countries. Their use is often driven by the limited availability or cost of commercial pesticides. Homemade botanical insecticides are often recommended by agricultural extension services and some development organizations. However, this could be questioned because scientific evidence of their efficacy and safety may not be available or accessible. Although botanicals with insecticidal properties have been widely studied, a synthesis focusing specifically on homemade preparations used in realistic field or storage conditions is missing. In this paper, we review efficacy assessments of botanicals used to prepare homemade insecticides. This covers twelve botanicals recommended by national extension partners in 20 countries within the global agricultural Plantwise program. These are as follows: garlic (Allium sativum), neem (Azadirachta indica), chili pepper (Capsicum spp.), Siam weed (Chromolaena odorata), mother of cocoa (Gliricidia sepium), chinaberry (Melia azedarach), moringa (Moringa oleifera), tobacco (Nicotiana tabacum), clove basil (Ocimum gratissimum), tephrosia (Tephrosia vogelii), tree marigold (Tithonia diversifolia), and bitter leaf (Vernonia amygdalina). This review shows that (1) all the selected botanicals contain active ingredients with insecticidal, antifeedant, or repellent properties, and (2) homemade insecticides based on all the selected botanicals have been used with some success to control pests or prevent damage, although efficacy was variable and often lower than the positive controls (synthetic pesticides). Factors affecting the efficacy of homemade botanical insecticide include variation in active ingredient content and concentration in plant material, as well as variation in the preparation process. In conclusion, there is some evidence that homemade botanical insecticides could contribute to reducing losses in food production. Since further research is needed to better understand their variable efficacy and potential health and environmental risks, those who promote the use of homemade botanical insecticides should also communicate those "unknowns" to the farmers who use such products.

“…Also, Ojiako et al, (2013) had found that M. oleifera seed extracts reduced the number of Megalurothrips sjostedti and A crassivora. Also, M. oleifera extracts had 62 % reduction of Phyllotreta cruciferae (Alao and Adebayo, 2015). Using plant extracts as bio-pesticides offering the farmers many unique benefits, it is usually are inherently less harmful than conventional the pesticides (John and Jimmy, 2015).…”

In this study, Moringa oleifera leaves were extracted by ethanol 70% and the contents of total phenolic and total flavonoids were estimated by using spectrophotometer methods and HPLC analysis. The content of total phenolic in the ethanolic extract of M. oleifera leaves was 11.66 g GAE/100 g ethanolic extract. The content of total flavonoids in the ethanolic extract of M. oleifera leaves was 4.52 g IQE/100g extract. Twenty five components were represented in the tested sample by HPLC. The study also aimed to evaluate the M. oleifera extract (ethanolic extract) prepared from M. oleifera leaves, as a natural insecticide and thiamethoxam (80 g / fed.) as a comparative insecticide against aphid, Aphis craccivora on broad bean (Vicia faba L.) plants in Faculty of Agriculture farm, Sharkia Governorate, Egypt during the 2017 season. A series of concentrations were prepared from M. oleifera extract, concentrations 1, 2, 4 and 8%. The results obtained that the reduction percentage in the population of aphid insect increases with increasing concentration of M. oleifera extract (1% -8%). The concentrations of 2 and 4% of M. oleifera extract caused 48.66 and 58.95 % mortality, respectively. The results also revealed that there is no significant differences between thiamethoxam and 8% M. oleifera leaf extract, there are recorded the highest values in reducing the population of the insect tested compared with the control treatment. The results indicate that biomaterials derived from M. oleifera leaves can be used for integrated pest management, which is a good alternative to conventional synthetic insecticides.

“…In Kenya, where both cutaneous and visceral leishmaniases are andemic and are conditions. The study was carried out using only the preemerginal stages because female adults feed on blood and both sexes suitable plant for carbohydrates [22]. It was envisaged that targeting the pre-emerginal stages can be achieved through introduction of the crude dried T. vogelii into the termite mound and animal burrow breeding and resting sites of the sand fl ies.…”

The effi cacy of allopatric Tephrosia vogelii in killing eggs and larvae of the sand fl y Phlebotomus duboscqi was tested in the laboratory. In this study effects of both water and crude powder extracs of Tephrosia vogelii were tested against against pre-emerginal stages of P. duboscqi in the laboratory. Three groups of eggs were wetted with T. vogelii extracts from Kilifi (TVK), Nairobi (TVN) and Vihiga Counties (TVV) and observed for morphological changes, motility, transformation and death. Six groups of 30 fi rst instar larvae were fed on T. vogelii crude powder either alone or mixed with larvae food. All larvae given TVN powder become immortile, did not feed and died at the fi rst instar stage, whereas those fed on TVV and TVK did not die. Combining all the three extracts also led the death of all fi rst and second instar larvae, but gradual death and disintegration of third instar larvae was sequentially observed. The differences in activities of the allopatric plants can be attributed to allopatric introgression arising from geopgraphic separation leading to introgressive hybridization. The killing and anti-feedant activities of TVN could also mean that it is a chemotype 1 plant that contains rotenoid whereas TVK and TVV are chemotype 2 that lack rotenoids. Feeding deterrence has been shown to be caused by rutin and quercetin. Considering that only leaves were used, the toxicity of TVN can be attributed to single or combination actions of rotenone, elliptone, deguelin, rutin, rotenolone, tephrosin or quercetin that have been shown to be present in leaves. Results of this study suggest that T. vogelli has detrimental insecticidal effects on pre-emerginal stages of P. duboscqi and has potential for sand fl y control. This control method can be achieved through direct introduction of crude dried T. vogelii powder into termite mound ventilation shafts and animal burrows where sand fl ies are known to breed and rest.
