O objetivo deste trabalho foi avaliar a patogenicidade de Beauveria bassiana a ninfas de Diaphorina citri (Hemiptera: Psyllidae) e verificar a compatibilidade do fungo com produtos fitossanitários e sua persistência em plantas de citros. Ninfas de D. citri foram pulverizadas com B. bassiana, nas concentrações 5x10(6), 1x10(7), 5x10(7), 1x10(8), 5x10(8) e 1x10(9) conídios mL-1, para determinação da concentração letal. Para avaliação da compatibilidade do fungo com produtos fitossanitários, extrato de nim e cinco inseticidas de quatro grupos químicos diferentes foram incorporados individualmente ao meio de cultura BDA em que o fungo foi cultivado. Avaliaram-se o crescimento vegetativo, a esporulação e a viabilidade do entomopatógeno. Plantas de citros, mantidas em casa de vegetação, foram tratadas primeiramente com os produtos fitossanitários e depois com o entomopatógeno. Avaliaram-se os tempos de exposição de 24 horas e de 7 e 14 dias. O fungo foi patogênico às ninfas de D. citri; a CL50 foi de 0,4x10(7) e a CL90 de 6,7x10(7) conidios mL-1, no décimo dia de avaliação. Em laboratório, os produtos fitosssanitários reduzem o crescimento do fungo. Em casa de vegetação, os produtos não afetam a sobrevivência do fungo nas plantas de citros.

RESUMO Avaliou-se a patogenicidade de diversas espécies de fungos entomopatogênicos a ninfas de 2o a 4o ínstares do psilídeo Diaphorina citri. Foram feitos bioensaios com Beauveria bassiana, Metarhizium anisopliae, Lecanicillium muscarum, L. longisporum, Paecilomyces fumosoroseus, P. farinosus, Syngliocladium sp. na concentração de 5 x 107 conídios/mL para cada patógeno, com exceção de Hirsutella thompsonii que foi aplicado na concentração de 2,8 x 107 conídios/mL. Utilizaram-se mudas de murta, Murraya paniculata, infestadas com as ninfas do inseto que foram pulverizadas com as suspensões conidiais dos patógenos. Os fungos B. bassiana, M. anisopliae, H. thompsonii, L. muscarum e P. fumosoroseus foram patogênicos para as ninfas do psilídeo. O isolado Esalq-PL63, de B. bassiana, causou mortalidade de aproximadamente 72% das ninfas, sete dias após a inoculação. Constatou-se que B. bassiananão conseguiu completar o desenvolvimento no corpo do hospedeiro, uma vez que a fase de conidiogênese não ocorreu. Mesmo assim, o isolado Esalq-PL63 pode ser considerado um promissor agente de controle microbiano de ninfas de D. citri por causar altos índices de mortalidade.

Natural enemies associated to Diaphorina citri in the state of Nayarit were identified. The study was carried out in three orchards of Persian lime from May to October 2011. The identified depredator species were Olla v-nigrum, Chilocorus cacti, Cycloneda sanguinea, and Ceraeochrysa sp.; as well as the parasitoid Tamarixia radiata and the entomopathogenic Beauveria bassiana. Nephus sp. Mulsant, 1850 and Pentilia sp. Mulsant, 1850 are new distribution records to Mexico.

Citrus Industry

Asian citrus psyllid (ACP), Diaphorina citri Kuwayama, is the most serious threat to the global citrus industry, and its management has mainly depended on the application of chemical insecticides. The use of biopesticides can play an important role in regulating this pest. In a first test, two separate experiments were conducted in two different municipalities (Apulo and Jerusalen, Cundinamarca, Colombia) to evaluate the effect of foliar Beauveria bassiana and imidacloprid sprays on ACP populations in 2015 and 2016, respectively. In a second test, two separate tests were carried out in commercial Tahiti lime orchards to evaluate the efficacy of three different commercial biopesticides (Beauveria bassiana and extracts of Sophora sp. and garlic-chili pepper). In test 1, imidacloprid-treated trees showed a reduction (60% and 80%) in cumulative ACP adults in 2016. ACP cumulative nymphs were also diminished by foliar imidacloprid and B. bassiana application, between 40% and 65% in 2015 and 2016, respectively. ACP cumulative eggs showed lower individuals in imidacloprid-treated flushes at 3 and 4 weeks after treatment 9 (WAT) in 2016. In test 2, the results obtained showed ACP adults and eggs unaffected by biopesticide treatments; nymphs were reduced 50% to 75% in trees treated with the three biopesticides in comparison with control trees. All three biopesticides tested can be considered useful tools in integrated pest management (IPM) programs for ACP, since these products reduced immature ACP individuals between 50% and 75% under field conditions.

Asiatic citrus psyllid Diaphorina citri Kuwayama has been considered as one of important citrus pests and a vector of a serious citrus disease as well, greening disease or known as Huanglongbing (HLB). Among entomophatogenic fungi which can be used to control those pest insects isBeauveria bassiana.The objective of this study was to measure the infectivity ofB. bassianaagainst adult of D. citri.B. bassianaconidia that used were 10<sup>3</sup>, 10<sup>4</sup>, 10<sup>5</sup>, 10<sup>6</sup>, 10<sup>7</sup>, and 10<sup>8</sup>conidia/ml.The experiment was repeated three times and arranged in a completely randomized design (CRD). Mean was analized by Duncan's multiple range test correction at the level α=0.05. B. bassianacaused mortality of D. citriat rate of 10%, 15%, 18.33%, 26.67%, 33.33% and 53.33% respectively. The result showed that LC<sub>50</sub> of B. bassianawas 1.52 x 10<sup>8</sup>conidia/ml.
