Thecountry’s share in this commodity chain is about US $14.6 billion anually,generating approximately 350 thousand jobs. Brazilian citrus is threatenedby yet another exotic pest, which arrived in 2004: the Asian citrus psyllidDiaphorina citri Kuwayama (Hemiptera: Psyllidae), vector of the citrusdisease huanglongbing (HLB or citrus greening), caused by the bacteriaCandidatus Liberibacter spp. Current chemical control practices for thispsyllid involves ineffective and expensive application of insecticides inorchards.Material and MethodsThe production of the first generation of D. aligarhensis in Brazil occurredbetween Jan 16th and Feb 1st 2017 (611 adults) Table I. Colonies of theseadults of D. aligarhensis have been established to perform competitionexperiments with another exotic parasitoid present in Brazil, Tamarixaradiata (Hymenoptera: Eulophidae), in order to fulfill the requirements priorto approval for release of D. aligarhensis in citrus orchards.Table I. Production of the first generation of Diaphorencyrtus aligarhensis inBrazil. Period: Jan 16th and Feb 1st 2017.ResultsThe exotic bioagent Diaphorencyrtus aligarhensis (Hymenoptera:Encyrtidae) was imported from California-USA through CaliforniaDepartment of Food and Agriculture (CDFA) to "Costa Lima" QuarantineFacilities of Embrapa Meio Ambiente in December 2016. The bioagentswere reared in cages on D. citri which were cultured on curry leaf plantsBergera (Murraya) koenigii (Sapondales: Rutaceae).ConclusionThe use of D. aligarhensis will be initiated in order to perform the biotests ofcompetition between another exotic parasitoid present in Brazil, Tamarixaradiata (Hymenoptera: Eulophidae), in order to request the releases of D.aligarhensis in citrus orchards.Diaphorencyrtus aligarhensis emergedDates 2017 Number of adultsJanuary 16th 117th 1918th 2519th 3020th 2621st 1622nd 4223rd 4024th 6025th 7228th 11029th 8030th 60February 01st 30Total adults 611Figure IV.
