This pest is common in Europe, but its presence in the Americas, particularly Brazil and Mexico, has been only recently reported in strawberry crops. Since its recent arrival in Mexico interest in the potential of different entomopathogens for the control of D. fovealis has increased

Suppression of Meloidogyne incognita by co-application of chitin and Streptomyces nigrescens (AMV1033) Biocontrol Sci. Technol. (IF 1.4) Pub Date : 2023-04-27 Caroline Eberlein, Andreas Westphal
ABSTRACT Root-knot nematodes, Meloidogyne spp., are among the most polyphagous and ubiquitous plant-parasitic nematodes. Among other management strategies, organic soil amendments and biological control agents are proposed. In this study, potential synergistic benefits of co-application of chitin and Streptomyces nigrescens (AMV1033) against M. incognita were determined. Hypothetically, chitinolytic

Occurrence and biocontrol potential of parasitoids on lychee cecid pest, Litchiomyia chinensis (Diptera: Cecidomyiidae) Biocontrol Sci. Technol. (IF 1.4) Pub Date : 2023-04-19 Yi-Min Chao, Sheng-Feng Lin, Michael W. Gates, Man-Miao Yang
ABSTRACT Lychee is an economically important fruit tree in sub-tropical area. The lychee pest, Litchiomyia chinensis Yang and Luo, induces blister-galls on the leaves of lychee crop and causes yield losses. Although chemical control may effectively suppress the pest population, insecticide resistance and environmental impact should be considered. It is preferable to develop more eco-friendly tactics

Toxicity of herbicides used for control of waterhyacinth in the California Delta towards the planthopper Megamelus scutellaris released for biological control Biocontrol Sci. Technol. (IF 1.4) Pub Date : 2023-04-18 Patrick J. Moran, John J. Miskella, Christy M. Morgan, John D. Madsen
ABSTRACT The water hyacinth planthopper Megamelus scutellaris has been released for biological control of waterhyacinth (Eichhornia crassipes or Pontederia crassipes) in Florida and is widely established there, with additional releases in Louisiana and California, USA, and in South Africa. Management still often requires the use of herbicides. Knowledge of their direct toxicity to M. scutellaris would

The response of the egg parasitoid, Trissolcus semistriatus (Nees) (Hymenoptera: Scelionidae) to metathoracic scent gland extract from Eurygaster maura (L.) (Hemiptera: Scutelleridae) Biocontrol Sci. Technol. (IF 1.4) Pub Date : 2023-04-17 Ekrem Ögür, Celal Tuncer
ABSTRACT This study was conducted in 2013–2014 in order to determine the response of the egg parasitoid, Trissolcus semistriatus (Nees) (Hymenoptera: Scelionidae) to metathoracic scent gland (MSG) extract from Eurygaster maura (L.) (Hemiptera: Scutelleridae) in laboratory conditions. For this purpose, the MSG extracts obtained separately from males and females were diluted with hexane and six different

Population genetics comparison of Lilioceris cheni (Coleoptera: Chrysomelidae) colonies released onto Dioscorea bulbifera in Southeastern U.S.A. Biocontrol Sci. Technol. (IF 1.4) Pub Date : 2023-04-17 Paul T. Madeira, Rodrigo Diaz, F. Allen Dray, Min B. Rayamajhi, Ellen Lake, Melissa Smith
ABSTRACT Multiple importations of Lilioceris cheni, a defoliating beetle of the invasive air potato plant, were received by the ARS-Invasive Plant Research Laboratory from 2002 to 2012. The last two, in 2011 (China) and 2012 (Nepal), formed the basis of two colonies from which releases were made into six Southeastern U.S. States. Colony populations were examined using the mitochondrial COI sequence
