Abstract

Balanites aegyptiaca (family: Zygophilaceae) otherwise known as desert dates is a prioritized species of many African, Middle East and South Asian countries due to its wide environmental adaptability, long living nature, easy regeneration from seeds and coppice, etc. Edible fruits, animal feed, firewood, soap, detergent, and high-quality charcoal are among the uses of this crop. It is also reported for ethnomedicinal uses to treat a variety of illnesses including jaundice, asthma, malaria, syphilis, epilepsy, haemorrhoids and more. Most significantly, it manages vector mosquitoes (eg. Aedes aegypti, Anopheles gambiae, Culex pipiens), which are considered as deadliest animals in the world. In present investigation, seed kernel extracted oil was tested for in-vitro bioassay against Hyblaea puera, a notorious lepidopteran defoliator of the highest valued timber crop Tectona grandis (teak) in India. This resulted in 77% mortality with 55% anti-feeding within 24 hours at 1% concentration. During the investigation, top five superior B. aegyptiaca populations have been identified based on seed availability and percentage of oil yield obtained by Duncan's Multiple Range Test (DMRT), Analysis of Variance (ANOVA). Of the 21 screened populations in Tamil Nadu, the maximum oil yield was obtained from Kalugumalai, Thoothukudi (63.17 ± 0.91), while the lowest was in Ammathur, Virudhunagar (38.43 ± 1.43). Additionally, a slight positive correlation (r=0.315) between seed area and oil yield percentage was discovered at 0.01 level of significance in 2-tailed Pearson's correlation. Further, methanol extracted the maximum number of phytochemicals with insecticidal potential, such as phenolic compound, tannin and saponin.
