“…Sex pheromones are species specific, active in small amounts, and generally non-toxic to animals [7]. This is in line with the statement which argued that the application of sex pheromones is more aimed at disrupting mating than to eradicate pest insect populations [8].…”

“…Sex pheromones have been identified in a number of insect pests, especially Lepidoptera [8]. Application of sex pheromones to control pests has been used for the Brassicaceae family, Copitarsiadecolora guenee (Lepidoptera: Noctuidae) [9]; and pests in vegetable, fiber, and ornamental plants, Helicoverpa spp.…”

Shallot (Allium ascalonicum L.) is one of the horticultural commodities that have high economic value in Indonesia. The caterpillar, Spodoptera exigua Hübner (Lepidoptera: Noctuidae), is an important pest of shallot crops which decreases both production and yield quality. Farmers commonly spray pesticides to control S. exigua. This can cause negative impacts on the environment and farmers’ health. Therefore, environmentally friendly control measures need to be implemented. Use of sex pheromone traps can be an alternative in controlling S. exigua. This research aims to study the effect of moonlight and rainfall on the number of male imagos of S. exigua captured in sex pheromone traps and to study the correlation of the number of S. exigua imagos captured on the percentage of infested leaves and shallot yield. This study was conducted from March to June 2016 in Labuhan Lombok Village, East Lombok Regency, West Nusa Tenggara (NTB) Province, Indonesia. Sex pheromone traps were randomly set on 12 shallot cultivation plots (Super Phillips variety). The number of male moths caught was recorded every 3-4 days, and then at the end of observations the percentage of infested leaves was determined. The number of captured male imagos of S. exigua had a significant linear relationship with the percentage of infested leaves and shallot yield with the correlation coefficient values of -0.607 and 0.829 respectively. The application of sex pheromone traps to control S. exigua on shallot, during moonlight and rainfall, has the potential to decrease both insecticide and production cost and to increase farmers’ income.

“…Semiochemical-based management of insects usually include pheromone lure and kill, mass trapping and disruption of mating activities [47,180]. Pheromones can also be effectively utilised in population monitoring to determine action thresholds, early pest detection and other manipulations of insect pest behaviour [181]. This form of control has been successfully implemented in South America, Europe, Asia and Africa in managing T. absoluta in greenhouses and open fields [42,81].…”

The South American tomato pinworm Tuta absoluta (Meyrick) has aggressively invaded the African continent. Since its first detection in North Africa in Morocco and Tunisia in 2008, it has successfully invaded the entire southern, eastern and western Africa, where it has been on the offensive, causing significant damage to Solanaceous food crops. While control of this prolific invader is primarily based on conventional synthetic pesticides, this form of control is consistently losing societal approval owing to (1) pesticide resistance development and consequential loss of field efficacy; (2) growing public health concerns; (3) environmental contamination and loss of biological diversity and its associated ecological services; and (4) unsustainable costs, particularly for resource-poor African farmers. As such, more ecologically sound pest management strategies, e.g., the use of natural substances (NSs), may offer a more sustainable approach to tackling this offensive. A systematic literature search through digital libraries and online databases (JSTOR, PubMed, Web of Science, SCOPUS and Google Scholar) was conducted using predetermined keywords on T. absoluta, e.g., South American tomato pinworm. We use this to explain the invasion of T. absoluta in Africa, citing mechanisms facilitating African invasion and exploring the potential of its control using diverse biological control agents, natural and low-risk substances. Specifically, we explore how botanicals, entomopathogens, semiochemicals, predators, parasitoids, host plant resistance, sterile insect technique and others have been spatially employed to control T. absoluta and discuss the potential of these control agents in African landscapes using more integrated approaches. We discuss the use of NSs as assets to general insect pest control, some potential associated liabilities and explain the potential use and barriers to adoption in African systems from a legislative, economic, ecological and social standpoint.
