Insect pest

Mealybug management

Mealybugs feed on plant sap and can weaken crops. Heavy infestations may reduce crop quality and stunt growth, while honeydew can support sooty mold development.

Monitoring focus

Regular field observation and early identification help growers understand where populations are developing and how crop health is affected.

Management perspective

Integrated management combines monitoring and practical interventions while considering beneficial insects and the production system.

Insect pest

Thrips monitoring & control

Thrips can damage leaves, flowers, and fruit surfaces. Some species also transmit plant viruses, making accurate identification and crop-specific assessment important.

Monitoring focus

Timely scouting, observation of crop damage, and population monitoring help assess pest pressure and inform management timing.

Management perspective

Preventive practices and integrated pest management strategies should reflect the thrips species, crop stage, and field conditions.

Citrus health

Asian citrus psyllid & HLB

Asian citrus psyllid (ACP) can transmit the bacterium associated with huanglongbing (HLB). HLB can reduce fruit quality and yield, cause tree decline, and eventually kill affected citrus trees.

Monitoring focus

ACP monitoring includes observation of new growth, visual surveys, tap sampling, and yellow sticky cards. Methods should be selected for the monitoring objective.

Recognition & diagnosis

HLB symptoms may include asymmetrical leaf mottling and misshapen fruit, but similar symptoms can have other causes. Suspected problems require appropriate diagnostic assessment.
