Moths will be collected at natural locations approximately 150-300 km away from the Kazakstan lab. New populations will also be identified and monitored in nearby western China. Tests will be conducted to determine the best method to develop moths to the next adult stage in both wild and confinement (laboratory) locations. Developed galls will be collected in the field and placed on new plants in both field and confinement conditions. Alternatively, recently emerged adults or eggs will be transferred to determine best transfer method. A weather monitor will be established at existing populations to correlate phenology with climatic data. Moths will be reared on both native saltcedar and accessions from the USA invasion. Main variables to be tested for rearing are temperature regime, humidity, size and age of host plant, amount of time that gall can be off tree, light regime, nectar source, number of moths and sex ratio for mating in confinement, size of confinement cage, etc.).
