π Invasive ants team up with pests in California groves
Invasive Argentine ants are surprisingly protecting pests like aphids and mealybugs in California's citrus groves and vineyards. These ants, originally from South America, were first spotted in the US around 1891 and established in California by 1907. Their linked colonies, spanning from San Diego to Ukiah, can overwhelm native ants by cooperating across vast areas. Farmers are seeing reduced natural pest control and irrigation issues because of this unlikely alliance. Management requires tackling both the ants and the honeydew-producing pests as one connected problem. π
