What is it about?
Maize stem borer (Chilo Partellus), poses a substantial threat to maize crops all over the world, causing damage that ranges from 26.7% to 80.4%. Its destructive impact includes killing the shoot in young plants, leading to a “dead heart,” and damaging the upper stem in older plants through boring activity. To combat this issue, a field experiment evaluated various insect growth regulators (IGRs) such as Lufenuron®, Pyriproxyfen®, Sitara®, Viper®, Track®, and Priority®.

Why is it important?
These IGRs, known as reduced-risk pesticides, target pest juveniles and are less harmful to beneficial insects. Conducted through a Randomized Complete Block Design (RCBD) with 24 treatments, excluding a control group, the study recorded maize stem borer populations at 3, 7, and 14 days post-IGR application. In conclusion, the study identifies pyriproxyfen® and Priority® at double the standard concentrations as highly effective insect growth regulators in mitigating maize stem borer infestations, offering promising avenues for enhanced pest control strategies in maize cultivation.
Perspectives
Agriculture, serving as the backbone of the economy, employs 50% of the total national labor force and contributes 25% to the GDP, while remarkably accounting for 85% of the country’s export earnings []. Maize (Zea mays L.) serves as a popular fodder crop and is cultivated across an expanse of 967 thousand hectares, generating an annual production of 1731 thousand tons, with an average yield of 1970 kg per hectare in Pakistan [2,3]. Maize has high nutritive value as it contains 72% starch, 10% protein, 4.80% oil, 9.50% fiber, 3.0% sugar, and 1.70% ash.
