Heat and counter map showing probability of hybridization. Interpolation using inverse distance weighting (IDW) method based on hybridization frequencies detected at each location. Insects were considered hybrid when genetic partition values were within 0.05 ≤ \( \hat{q} \) ≤ 0.95 for H. armigera partition and 0.05 ≤ \( \hat{q} \) ≤ 0.95 for H. zea partition of STRUCTURE analysis using K = 2. Darker color indicates higher probability of hybridization. Landscapes at each location represent land-use composition at approximately the time of the collection
