“…Nonetheless, recent studies have indicated that ‘ Bt- cotton’ cultivars have been losing resistance against various insects [ 10 – 14 ]. Although Alam et al [ 34 ] reported that ‘ Bt -cotton’ cultivar ‘FH-634’ had the highest resistant to the sucking insects, we found that ‘FH-682’ was most resistant to jassid and had the highest susceptibility to whitefly. Shahid et al [ 35 ] found that cultivar ‘FH-118’ exhibited highest resistance to thrips, whereas cultivars ‘FH-17’, ‘FH-114’ and ‘FH-179’ proved most susceptible to thrips.…”

Cotton ( Gossypium hirsutum L.), being a cash and fiber crop is of high significance in Pakistan. Numerous insect pests and viral diseases in Pakistan and around the world attack cotton crop. Genetically modified cotton (transgenic, resistant to lepidopteran insects), hereafter written as ‘ Bt -cotton’ has been introduced in many regions of the world to combat bollworms. However, cultivars differ in their pest susceptibility, yield response and fiber quality traits. Nonetheless, recent studies have indicated that lepidopteran pests are evolving resistance against ‘ Bt -cotton’. Several ‘ Bt -cotton’ cultivars have been developed in Pakistan in the past decade; however, limited is known about their pest susceptibility, seed-cotton yield and fiber quality traits. This two-year field study evaluated pest susceptibility, yield and fiber quality traits of thirteen newly developed ‘ Bt -cotton’ cultivars in Pakistan. The cultivars differed in their susceptibility to sucking insects during both years of study. The cultivars ‘FH-647’, ‘SLH-8’, ‘FH-Lalazar’ and ‘IUB-013’ were more susceptible to jassid, whereas ‘BS-52’ exhibited higher susceptibility to whitefly during both years of study. Similarly, cultivars ‘AGC-999’ and ‘MNH-992’ proved highly susceptible to thrips during each study year. Although ‘ Bt- cotton’ is resistant to bollworms, cultivars ‘SLAH-8’, ‘VH-305’ and ‘BH-184’ were susceptible to spotted bollworm, while ‘SLAH-8’, ‘RH-647’ and ‘VH-305’ were infested by American bollworm. The most susceptible cultivars to cotton leaf curl virus (CLCuV) attack were ‘RH-647’, ‘IR-NIBGE-7’ and ‘VH-305’. The highest seed-cotton yield was recorded for ‘FH-Lalazar’ during both years of study. Similarly, the highest ginning out turn was recorded for cultivars ‘BS-52’, ‘VH-305’, ‘RH-647’, ‘IUB’ and ‘AA-919’. The cultivar ‘FH-Lalazar’ exhibited low pest susceptibility and CLCuV infestation compared to the rest of cultivars. The highest and the lowest gross and net incomes and benefit:cost ratio were noted for ‘FH-Lalazar’ and ‘RH-647, respectively. Keeping in view the low pest susceptibility and high seed-cotton yield, ‘FH-Lalazar’ could be recommended for higher yield and economic returns in Multan, Pakistan. Nonetheless, regional trials should be conducted for site-specific or region-specific recommendations.

“…Plianbangchang et al [25] and Alam et al [47] emphasized that IPM, as an ecological method and environmentally friendly technology, is a multi-faceted approach to pest management that seeks to minimize the negative impacts on the environment. Therefore, it is evident that farmers with IPM experience consider environmental criteria more important when selecting and using pesticides.…”

Farmers’ Criteria for Pesticide Selection and Use in the Pest Control Process

Chemical pesticides have been widely overused by farmers in Iran, but farmers' criteria for pesticide selection and use are not well understood. A field survey of 411 farmers was carried out in Mazandaran, Iran, to study farmers' criteria for selecting and using pesticides in the pest control process and explaining differences in selection criteria among farmers. From a list with a total of 25 criteria, five main groups were identified as key decision criteria for pesticide selection and use, using factor analysis. These groups included: (i) performance and effectiveness criteria, (ii) awareness and information criteria, (iii) technical and operational criteria, (iv) environmental criteria, and (v) financial and accessibility criteria. Performance and effectiveness criteria had the highest importance for farmers when selecting and using pesticides (mean 3.45), followed by financial and accessibility criteria (mean 3.28). Farmers who received training regarding pesticide use (mean 2.23 vs. 1.90) and farmers who had experience with integrated pest management (IPM) practices (mean 2.46 vs. 1.79) tended to consider environmental criteria when selecting and using pesticides. Similarly, farmers who experienced health risks related to working with pesticides (mean 2.0 vs. 1.77), farmers who used protection when spraying (mean 2.58 vs. 1.87), and farmers who knew about natural enemies of pests (mean 2.11 vs. 1.85) tended to consider environmental criteria when selecting and using pesticides. Farmers without off-farm income tended to consider financial and accessibility criteria more than farmers with off-farm income (mean 3.40 vs. 3.18). Farmers with college education favored awareness and information criteria, whereas experienced farmers favored the criteria of performance and effectiveness. Farmers with a high income showed a tendency to prefer performance and effectiveness criteria more than farmers with less income. Farmers who thought that pesticides are hazardous preferred environmental criteria more than farmers who thought that pesticides are not hazardous. Farmers who believed in the effectiveness of alternatives to chemical pest control (e.g., use of biological control, pheromone traps, or cultural control) preferred performance and effectiveness criteria less than farmers who believed no effectiveness or slight effectiveness of alternatives to chemical pest control. The findings provide useful information for better understanding factors affecting farmers' choices of pesticides and for improving future extension courses related to farmers' decisions about pesticide use.

“…Integrated pest management is a dynamic and constantly evolving approach to crop protection in which all the suitable management tactics and available surveillance information are utilized to develop a holistic management program. Sustainable pest management aims to minimize the destruction of the natural environment and achieve a high and profitable yield [ 164 ]. PSMs are natural products that are effective against insect pests.…”

Plants have evolved several adaptive strategies through physiological changes in response to herbivore attacks. Plant secondary metabolites (PSMs) are synthesized to provide defensive functions and regulate defense signaling pathways to safeguard plants against herbivores. Herbivore injury initiates complex reactions which ultimately lead to synthesis and accumulation of PSMs. The biosynthesis of these metabolites is regulated by the interplay of signaling molecules comprising phytohormones. Plant volatile metabolites are released upon herbivore attack and are capable of directly inducing or priming hormonal defense signaling pathways. Secondary metabolites enable plants to quickly detect herbivore attacks and respond in a timely way in a rapidly changing scenario of pest and environment. Several studies have suggested that the potential for adaptation and/or resistance by insect herbivores to secondary metabolites is limited. These metabolites cause direct toxicity to insect pests, stimulate antixenosis mechanisms in plants to insect herbivores, and, by recruiting herbivore natural enemies, indirectly protect the plants. Herbivores adapt to secondary metabolites by the up/down regulation of sensory genes, and sequestration or detoxification of toxic metabolites. PSMs modulate multi-trophic interactions involving host plants, herbivores, natural enemies and pollinators. Although the role of secondary metabolites in plant-pollinator interplay has been little explored, several reports suggest that both plants and pollinators are mutually benefited. Molecular insights into the regulatory proteins and genes involved in the biosynthesis of secondary metabolites will pave the way for the metabolic engineering of biosynthetic pathway intermediates for improving plant tolerance to herbivores. This review throws light on the role of PSMs in modulating multi-trophic interactions, contributing to the knowledge of plant-herbivore interactions to enable their management in an eco-friendly and sustainable manner.
