Studies with psyllid pheromones show that the insect’s behavior is altered when it is infected by the HLB-causing bacterium Candidatus Liberibacter (CLas). This makes it difficult to produce a commercial psyllid-control product based on the insect pheromone, Brazil’s Fundecitrus has concluded. “The sexual pheromone is an attractant produced by the female of the species, which promotes behavioral changes in male …

New Discovery About Asian Citrus Psyllids
A failed field test has led to a major discovery about Asian citrus psyllids (ACP). According to new research, the bacterium that causes HLB disease can interfere with ACP’s sense of smell, rendering some kinds of insect traps useless. The work is currently available as a preprint. HLB, also known as citrus greening, is caused by the Candidatus Liberibacter asiaticus (CLas) bacterium. …

ORANGESEU orange production is projected to reach 5.4 million metric tons (MT) in 2023–24, down 2% from the already short EU orange output level …
New Research on Neonicotinoids for Psyllids
Continuing Brazilian research into the application of neonicotinoids via drench for control of HLB-spreading psyllids shows higher efficacy than earlier results indicated. In September, Fundecitrus released preliminary results on the application of neonicotinoids via drench. At that time, tests carried out on a property in Casa Branca, São Paulo, showed that the efficiency of the molecules for this type of …
Preventing Pesticide Resistance
By Lourdes Pérez Cordero Insects in general are often thought of as pests. Although some organisms of the class Insecta can become harmful to important agricultural crops, not all insects should inherently be considered pests. A pest can be any organism that competes, injures, or spreads diseases to humans, domestic animals and desired plants. Historically, humans have utilized chemical mixtures …
