TLDR
The results showed that the two plant extracts can be used in the control of insect pests of the watermelon, and the effectiveness of the two plants extracts were concentration dependent.Abstract:
Despite the fact that synthetic insecticides are fast acting, they constitute environmental hazard thereby necessitating the use of ecologically based alternative such as plant based insecticide. This experiment was conducted during the late and early planting seasons of 2011 to determine the insecticidal efficacy of Tephrosia vogelii and Moringa oleifera extracts at three tested concentrations (5, 10 and 20% v/v) against insect pests of watermelon. The experiment was set up in a randomized complete block design with three replicates. The results showed that M. oleifera extracts had 62% reduction of Phyllotreta cruciferae compared with T. vogelii which had 45% control. However, T. vogelii extracts had 64% control of Diabrotica undecimpunctata and Bactrocera curcubitea but M. olefera extracts had 50% control. The plant extracts proved effective against studied insects when compared with untreated plots. However, the effectiveness of the two plants extracts were concentration dependent. Therefore, the two plant extracts can be used in the control of insect pests of the watermelon.read more

Plants in the Genus Tephrosia: Valuable Resources for Botanical Insecticides
TL;DR: It is argued that a systematic evaluation of bioactive compounds in different species are needed, and species or strains with high insecticidal activities should be selected for use in the sustainable control of insect pests.

Effectiveness of Tephrosia vogelii and Tephrosia candida Extracts against Common Bean Aphid (Aphis fabae) in Malawi
TL;DR: Though these two plant extracts were not as effective as the synthetic insecticide in reducing aphid population, they were considerably and significantly found to be effective; hence, their use by poor-resource farmers is recommended in the protection of bean against aphid.

TL;DR: There is an absence of interdisciplinary studies that addressed the wider indirect benefits of not using chemical pesticides, the social-economic outcomes, and barriers to adoption by farmers, which it is argued are necessary to identify pathways to greater adoption and to support policy advocacy of biocontrol interventions in SSA.

TL;DR: 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.
Diversity, spatial and temporal distribution of above-ground arthropods associated with watermelon in the Nigerian southern guinea savanna
TL;DR: In this article, the diversity, spatial and temporal distribution of aboveground arthropods associated with watermelon in the Nigerian southern guinea savanna was investigated, and the results showed that the arthropod diversity was positively associated with the watermelon harvest.

Botanical insecticides, deterrents, and repellents in modern agriculture and an increasingly regulated world
TL;DR: In the context of agricultural pest management, botanical insecticides are best suited for use in organic food production in industrialized countries but can play a much greater role in the production and postharvest protection of food in developing countries.

The melon fruit fly, Bactrocera cucurbitae: a review of its biology and management.
TL;DR: The melon fruit fly can be managed over a local area by bagging fruits, field sanitation, protein baits, cue-lure traps, growing fruit fly-resistant genotypes, augmentation of biocontrol agents, and soft insecticides, and over a wide area by the coordination of different characteristics of an insect eradication program.

TL;DR: Because of interspecific differences in response to feeding deterrents and the lack of a strong relationship between EC50 and DC50 values, it is recommended to testing a battery of bioassay species with candidate compounds and the use of more than one bioassays.

Flesh quality and lycopene stability of fresh-cut watermelon
TL;DR: In this article, the authors evaluated the stability of lycopene in cut watermelons for 2, 7, or 10 days, at each storage interval, and evaluated for juice leakage, changes in carotenoid composition, color, soluble solids content, and titratable acidity.

TL;DR: Neem inhibited oviposition, larval development and feeding, and greatly increased mortality in these studies, and NeemAzal-T protected plants from damage for at least three weeks if applied before ovipposition, or at least two weeksif applied against 2nd instar larvae.
