Since the first identification of the silkworm moth sex pheromone in 1959, significant research has been reported on identifying and unravelling the sex pheromone mechanisms of hundreds of insect species. In the past two decades, the number of research studies on new insect pheromones, pheromone biosynthesis, mode of action, peripheral olfactory and neural mechanisms, and their practical applications in Integrated Pest Management has increased dramatically. An interdisciplinary approach that uses the advances and new techniques in analytical chemistry, chemical ecology, neurophysiology, genetics, and evolutionary and molecular biology has helped us to better understand the pheromone perception mechanisms and its practical application in agricultural pest management. In this review, we present the most recent developments in pheromone research and its application in the past two decades.

Defense Chemicals

Insect pests cause significant global agricultural damage and lead to major financial and environmental costs. Crops contain intrinsic defenses to protect themselves from such pests, including a wide array of specialized secondary metabolite-based defense chemicals. These chemicals can be induced upon attack (phytoalexins) or are constitutive (phytoanticipins), and can have a direct impact on the pests or be used indirectly to attract their natural enemies. They form part of a global arms race between the crops and their insect pests, with the insects developing methods of suppression, avoidance, detoxification, or even capture of their hosts defensive chemicals. Harnessing and optimizing the chemical defense capabilities of crops has the potential to aid in the continuing struggle to enhance or improve agricultural pest management. Such strategies include breeding for the restoration of defense chemicals from ancestral varieties, or cross-species transfer of defense metabolite production.

Increased Temperature

Increased temperature anomaly during the twenty-first century coincides with the proliferation of transgenic crops containing the bacterium Bacillus thuringiensis (Berliner) (Bt) to express insecticidal Cry proteins. Increasing temperatures profoundly affect insect life histories and agricultural pest management. However, the implications of climate change on Bt crop–pest interactions and insect resistance to Bt crops remains unexamined. We analysed the relationship of temperature anomaly and Bt adoption with field-evolved resistance to Cry1Ab Bt sweet corn in a major pest, Helicoverpa zea (Boddie). Increased Bt adoption during 1996–2016 suppressed H. zea populations, but increased temperature anomaly buffers population reduction. Temperature anomaly and its interaction with elevated selection pressure from high Bt acreage probably accelerated the Bt-resistance development. Helicoverpa zea damage to corn ears, kernel area consumed, mean instars and proportion of late instars in Bt varieties increased with Bt adoption and temperature anomaly, through additive or interactive effects. Risk of Bt-resistant H. zea spreading is high given extensive Bt adoption, and the expected increase in overwintering and migration. Our study highlights the challenges posed by climate change for Bt biotechnology-based agricultural pest management, and the need to incorporate evolutionary processes affected by climate change into Bt-resistance management programmes.

Pest Control Methods

Agricultural pest management control strategies are primarily concerned with food security and safety. Popular pest control methods include application of synthetic pesticides, biopesticides (plant extracts), non-chemical pest management and integrated pest management (IPM). The resistance of some of the pests to the chemical pesticides, coupled with potential health hazards on the environment gave birth to a search for botanicals as alternatives to synthetic pesticides. Botanicals as biopesticides were, though effective but their shelf lives and specific actions on the target organisms have not been determined. Non-chemical pest control methods involve common cultural practices which include crop rotation, tillage, and varying time of planting or harvesting, trap cropping which appear to be the best in terms of food safety and quality but the ability of this approach to reduce pest population may be minimal. Because no single pest control method can guarantee food security and safety, integrated pest management (IPM) approach appears to hold promise. The IPM is an ecologically based approach that combines all the available pest control methods to manage pest damage by the most economical means, with the fewest possible hazards to life, property and environment. However, this review shows that the impact of integrated pest management in the rural farm communities is low. In an era of growing consumer awareness and sophistication, food quality is being emphasized. Food safety means that the agro-products should be free from pesticide residues:- therefore, aspects of farm management such as sources of seeds and seedlings, pests and weed elimination, pesticide application dates, dates and amount of fertilization, harvesting or post harvest treatments and basic information regarding the individual farmer or marketing agents activities should be certified before consuming agricultural products. Federal governments especially in developing countries are advised to mount regulating Agencies that will be responsible for a number of activities that contribute to food security and safety, water quality and pesticide applicator training as practiced in the United States of America, India and Indonesia. The agencies will ensure that the public is protected from potential health risks posed by pesticide treated foods.
