1a.Objectives (from AD-416)
Investigate population dynamics of natural populations of Mexican fruit fly (Anastrepha ludens), serpentina fruit fly (A. serpentina), West Indian fruit fly (A. obliqua), and guava fruit fly (A. striata) on native and commercial host plants in Nuevo Leon and Tamaulipas, Mexico. Test baits for detection or eradication of these pests in the U.S. and Mexico. Monitor populations of Asian citrus psyllid and brown aphid and the citrus diseases, tristeza and huanglongbing in northeastern Mexico.
1b.Approach (from AD-416)
Populations of these species will be monitored by trapping and host fruit collection. Host plant lists will be determined by fruit collection in native forests and commercial orchards, with emphasis on foothill and mountain areas of Nuevo Leon. New baits will be developed in Weslaco, Texas, and tested on the native populations in traps and field trials of insecticidal baits. Optimal use of spray programs and bait station deployment will be determined in abandoned or nonproductive orchards bordering areas of high native host plant populations.
Activities in support of fruit fly and psyllid research, in cooperation with Instituto Nacional de Investigaciones Forestales, Agricolas y Pecuarias (INIFAP), involved testing of attractants and monitoring Asian citrus psyllid control. Field inspectors at the General Teran, Mexico, field station worked with the INIFAP scientists who provided information concerning spread of Huanglongbing (HLB) northward in Mexico and programs for psyllid control.
The ADODR is in contact with the cooperator by phone and email each quarter to discuss any modifications not specified in the original research agreement.
