“…Therefore, it can be inferred that intercropping and fertilizer reduction affect the uptake of nutrients in corn roots, resulting in yield differences, which is consistent with the results of Li et al (2022) previously published. Correlation analysis showed that with the increase of nitrogen, the number of Asian corn borers also showed a decreasing trend, which was similar to the results of previous studies (Klostermeyer, 1950). This study supports this conclusion to some extent.…”

“…The increase in N-fertilizer usage could inhibit the occurrence of potato pests to some extent ( Fragoyiannis et al, 2001 ). The rise in N-fertilizer usage also increased the tightness of corn husks, thus reducing the infection of corn earworms ( Klostermeyer, 1950 ). In addition, with the increase in N content in plant tissues, the population densities of sucking insect pests increased while the number of chewing insect pests decreased ( Pimentel and Warneke, 1989 ).…”

Corn is one of the key grain crops in China and the excessive use of chemical fertilizers and pesticides seriously damages the ecological environment in fields. To explore a more scientific and reasonable way to plant corn and simultaneously reduce the overuse of chemical fertilizers and pesticides, the impact of corn intercropping with soybean, peanut, and millet, respectively, through five planting patterns, including three intercropping patterns (2 corn rows to 2, 3 and 4 rows of soybean/peanut or 2, 4 and 6 millet rows, respectively) and two monoculture patterns of corn and soybean, peanut or millet under normal (600 kg/ha) and reduced (375 kg/ha) levels of NPK (N:P2O5:K2O = 15:15:15) fertilization on the population abundance and community diversity of insects, leaf nutrients, and induced plant hormones jasmonic acid (JA) and salicylic acid (SA) was studied in 2018 and 2019. The results showed that the insect community indexes of the species number (S), the diversity index (H), and the uniformity index (E) generally increased under intercropping and were significantly higher than those under corn monoculture. The prevalence of Asian corn borer (Ostrinia furnacalis) on the intercropping corn plants decreased by based on the average of seven surveys per year for each treatment 2.9 to 17 heads per 30 plants compared with that on the monoculture corn plants. The number of natural enemy insect species on corn plants under intercropping was significantly higher than that under corn monoculture. That is, intercropping may decrease the population of Asian corn borers by increasing S, H, E, and natural enemy insect species (NEI). Moreover, intercropping type and fertilizer level significantly affected corn leaf nutrient contents. Compared with the normal fertilizer level, fertilizer reduction significantly reduced the foliar contents of amino acids, soluble protein, and soluble sugar in corn plants. In addition, corn–soybean and corn–peanut intercropping significantly increased the three nutrient contents in corn leaves compared with corn monoculture. In terms of corn nutrients, intercropping could compensate for the effects of fertilizer reduction. The foliar content of JA in corn–soybean intercropping was significantly higher than in corn monoculture. Under corn–soybean and corn–peanut intercropping, SA was significantly lower than under corn monoculture. Overall, intercropping, not fertilizer reduction, can significantly increase insect community diversity while reducing the population abundances of the key insect pest species on corn plants. Intercropping reduced the SA content, increased amino acids and thus reduced the susceptibility of corn to the pest insects.

“…In addition, cultural methods such as crop fertilization can affect pest pressure, and further confound the intercropping experiments and the interpretation of the results. It is known that soil fertility management may affect plant quality and may therefore affect insect pest abundance ( Klostermeyer, 1950 ). Research shows that organically fertilized crops generally exhibit lower densities of several insect herbivores.…”

1 The effects of intercropping via competition on crop yields, pest [cabbage aphid Brevicoryne brassicae (L.)] abundance, and natural enemy efficacy were studied in the Brassica oleracea L. var. italica system. 2 From May to December 2004, insect populations and yield parameters were monitored in summer and autumn in broccoli monoculture and polyculture systems with or without competition from Brassica spp. (mustard), or Fagopyrum esculentum Moench (buckwheat), with addition of organic (compost) or synthetic fertilizer. 3 Competition from buckwheat and mustard intercrops did not influence pest density on broccoli; rather, aphid pressure decreased and natural enemies of cabbage aphid were enhanced in intercropping treatments, but this varied with the intercropped plant and season (summer vs. autumn). 4 In compost-fertilized broccoli systems, seasonal parasitization rates of B. brassicae by Diaeretiella rapae (M'Intosh) increased along with the expected lower aphid pressure compared with synthetically fertilized plants.

“…Plant resistance to several insect pests has been documented to be influenced indirectly by fertilization practices operating through changes in crop nutrient content. Excessive and/or incorrect application of inorganic fertilizers might result in nutritional imbalances and decreased insect resistance [78]. Proper fertilization is required to provide the plants with some level of pest resistance.…”

Sustainable agriculture plays a vital role in modern farming, addressing concerns of traditional pesticides, which raise issues related to safety, environmental impact, and resistance. Consequently, alternative insect pest management methods, including nutrient-based approaches, have gained prominence. However, understanding the relationship between nutrients and plant diseases remains a complex challenge. This review synthesizes recent insights on the impact of specific nutrients (N, P, K, Mn, Zn, B, Cl and Si) on insect pest resistance in sustainable agriculture. Nitrogen supply has a major impact on insect pest intensity as compared to low nitrogen doses and control, pest populations were high at high levels. Phosphorus (P) has an inconsistent role in resistance. Comprehensive nutrient management in sustainable agriculture offers cost-effective, eco-friendly disease control, reducing pesticide reliance. Potassium (K) enhances resistance to an optimal point, beyond which there is no further improvement. Proper nutrient management can make subsequent control measures more efficient and economical. Understanding the interplay of plant nutrition, insect herbivores, and community dynamics is essential. Balanced nutrient levels, especially potassium and phosphorus, indirectly strengthen plant resistance to various insect pests through biochemical, physical, and mechanical mechanisms. Strategies to enhance plant defense against phytophagous insects align with the demand for food and nutritional security. This review emphasizes the significance of comprehensive nutrient management in sustainable agriculture for disease and pest control while prioritizing food safety and environmental quality.
