The average capture rate of psyllids in traps distributed across 23 regions of the citrus-growing area of São Paulo and the Southwest Minas Gerais Triangle in Brazil has fallen for the second consecutive year. The information provided by the Fundecitrus Psyllid Alert platform confirms a downward trend after the peak recorded in 2023. It indicates a scenario of lower pest pressure, associated with the continuation of control actions and less favorable weather conditions.
The record capture rate in 2023 was an average of 2.23 psyllids per trap. The numbers have declined since. The 2024 average capture rate fell to 1.32. In 2025, there was a further reduction to 1 psyllid per trap.
Even though 2025 confirms the sequence of two consecutive years of psyllid decline, it is still classified as a year of moderate to high occurrence.
SHOOT GROWTH
The consolidated data from the Psyllid Alert platform also indicates that 2025 registered the highest level of shoot growth throughout the entire period analyzed. A significant increase in the supply of shoots like that in 2025 is normally favorable to the development of the psyllid. Instead, the pest’s behavior went in the opposite direction, with a reduction in captures throughout the year.
“Even with shoot growth at the highest level in the historical series, the psyllid population decreased, contradicting the trend observed in previous years,” said Ivaldo Sala, coordinator of Fundecitrus’ Technology Transfer Department. “This demonstrates that citrus growers are doing their part, adopting the control measures recommended by Fundecitrus for efficient management.”
ABOUT THE PSYLLID ALERT
The Psyllid Alert is a free tool provided by Fundecitrus with the objective of anticipating risk scenarios. Based on data collected in the field, the platform indicates the periods in which the insect pressure tends to increase in the orchards.
