Testes em condições para o controle de Dysmicoccus texensis (Tinsley) (Hemiptera, Pseudococcidae) em cafeeiro com nematóides entomopatogênicos do gênero Heterorhabditis(Rhabditida, Heterorhabditidae)

Insect Cadaver Applications: Pros and Cons

“…CCA and Heterorhabditis sp. JPM3 against Dysmicoccus texensis (Tinsley) (Hemiptera: Pseudococcidae) resulted in unsatisfactory control levels both in the greenhouse and field application (Alves, Moino, Santa-Cecilia, Rohde, & Silva, 2006). Although specific reasons for that are not mentioned by the authors, we can hypothesize that the environmental conditions were not favorable for IJs to exit from the insect cadaver or for their movement in the soil.…”

Studies on entomopathogenic nematodes in Brazil: past and future

“…Alves et al [19] Alves et al [20] Guava weevil Conotrachelus psidii Guava H. indica IBCB n05 Field Silva et al [21] Mediterranean fruit fly…”

“…With respect to field trials, good results have been obtained against M. fimbriolata (sugarcane root spittlebug) [11] , C. psidii [13] , Ceratitis capitata (Wiedemann) (Diptera: Tephritidae) (fruit fly), Anastrepha fraterculus (Wied.) (Diptera: Tephritidae) (South American fruit fly), and D. texensis [20] . The combination of aqueous solutions of EPNs with insecticides is another interesting approach, due to possible synergetic or additive effects [87] .…”

“…The application of nematodes in insect cadavers was also efficient against snails of the species Bradybaena similaris (Fémssac) (Stylommatophora: Bradybaenidae) in the laboratory [41] and against spittlebug nymphs (M. spectabilis) in a greenhouse experiment [86] . Alves et al [20] conducted greenhouse and field tests to compare the efficiency of strains of Heterorhabditis, applied in aqueous suspension and insect cadavers, to control D. texensis adults. The authors reported that the best results, in the greenhouse and field, were obtained by applying an aqueous suspension containing H. amazonensis JPM3, with efficacy levels of 68% and 65%, respectively.…”

“…Another research group, from the Universidade Federal de Lavras (UFLA), coordinated by Alcides Moino Jr., has conducted important studies into the isolation, biology, in vivo production, storage and compatibility of EPNs with pesticides [50,59,79,80,101] . They also performed laboratory, greenhouse and field experiments indicating the potential of EPNs to control the mealybug D. texensis [19,20] . In 2008, the company Interação Produtos Biológicos (Interaction Biological Products) was established at UFLA with the cooperation of Dr. Claudia Dolinski and financial support from the Fundação de Amparo a Pesquisa do Estado de Minas Gerais (FAPEMIG).…”
