“…Our findings align closely with other field studies testing organic materials against different species of flea beetles. Taken together, most studies show consistently high levels of flea beetle suppression with Entrust and PyGanic, but limited efficacy with azadirachtin products [ 64 , 75 , 76 , 77 , 78 , 79 ].…”

There exists a lack of control efficacy information to enable decision-making about which organic insecticide product works best for a given insect pest. Here, we summarize results of 153 field trials on the control efficacy of common active ingredients in organic insecticides against 12 groups of the most difficult to control insect pests. These trials evaluated primarily the organic products Entrust (spinosad), Azera (pyrethrin and azadirachtin), PyGanic (pyrethrin) and Neemix (azadirachtin), which reduced pest infestations by an overall 73.9%, 61.7%, 48.6% and 46.1% respectively, averaged across all trials. Entrust was the most effective control option for many insect pests, particularly providing >75% control of flea beetles, Colorado potato beetle, cabbageworms and alfalfa weevil, but was relatively ineffective against true bugs and aphids. Azera provided >75% control of green peach aphid, flea beetles, Japanese beetle, Mexican bean beetle, potato leafhopper and cabbageworms. PyGanic was less effective than Entrust and Azera but still provided >75% control of green peach aphid, flea beetles and potato leafhopper. The growth inhibition effects of azadirachtin in Neemix were particularly effective against larvae of Mexican bean beetle and Colorado potato beetle but was generally less effective in trials with insect infestations consisting mainly of adult stages. Those insect pests that were particularly difficult to control included thrips, stinkbugs, cucumber beetles and fruitworms. Several caveats pertaining to the application of the results are discussed.

“…Our field was located next to fields growing clover, tomatoes, and radishes in the conventional section of the farm. To study the impact of row covers, essential oils, and organic and conventional insecticides, we performed two field trials grown on a 0.275-acre field site of arugula (Astro) and mustard greens (Mizuna) in the spring (11)(12)(13)(14)(15)(16)(17)(18)(19)(20) and fall (16 August-20 September) of 2019. In Kentucky, high temperatures in the mid-summer limit the success of mustard greens.…”

“…Only at high concentrations did application of cyantraniliprole result in lower flea beetle damage [ 15 ]. For organic growers, organic insecticides show some success at reducing flea beetle abundance and damage [ 16 ]. Andersen et al [ 14 ], found that an organic spinosyn mix reduced flea beetle damage compared to the control.…”

Brassicaceous leafy greens are an important crop for small growers but are difficult to produce due to damage by flea beetles. Flea beetles are problematic for growers as they chew many small holes through leaves rendering produce unmarketable. We tested the efficacy of several essential oils, the woven-mesh row cover ProtekNet, and the spunbonded row cover Agribon, compared to organic and conventional insecticides and no spray controls in the spring and fall of 2019. We found that the two row cover treatments (Agribon and ProtekNet) provided the best control of flea beetles and associated damage. Thyme oil was highly phytotoxic and killed the crop entirely and rosemary and neem essential oils caused mild phytotoxic burns. Organic insecticides rarely performed better than the no spray control. While conventional insecticides controlled most flea beetles, the crop was often still too highly damaged to sell. The results of our study suggest row covers offer producers an effective method of flea beetle control that reduces their dependence on insecticides for conventional and organic production.

Chromobacterium subtsugae é uma bactéria gram-negativa que vem sendo utilizada na agricultura, nos últimos anos, no manejo de diversas espécies de artrópodes-pragas, devido aos seus metabólitos tóxicos. Apesar de avanços na sua utilização, são escassas as informações acerca de sua patogenicidade no Brasil. Desse modo, a presente revisão bibliográfica objetiva compilar os dados mais recentes (2011-2021) sobre as características gerais de C. subtsugae, seu modo de ação e os resultados no manejo biológico de diferentes artrópodes-praga. O levantamento bibliográfico foi realizado nas plataformas Google Scholar, Periódicos Capes e Science Direct, com um filtro para o período de 2011-2021, utilizando a combinação de palavras: Chromobacterium subtsugae, bactéria entomopatogênica (entomopathogenic bacteria) e controle biológico (biological control). C. subtsugae evidencia vários efeitos em insetos-praga como toxicidade oral, repelência, redução da fecundidade em fêmeas e oviposição e, inibição da alimentação em indivíduos das ordens Hemiptera, Thysanoptera, Coleoptera, Diptera e Acari (ácaros fitófagos), sendo seu mecanismo de ação considerado complexo, podendo sintetizar no decurso da fermentação, três fatores inseticidas: cromamida A, violaceína e um composto não identificado. Perante tais elucidações, constata-se a importância da referida bactéria no desenvolvimento de novos produtos direcionados ao manejo de diversos insetos-praga, principalmente, pelo seu amplo espectro de ação. Ademais, espera-se que os dados levantados sirvam de referencial para pesquisas futuras com C. subtsugae, tanto em experimentos em campo quanto laboratoriais no Brasil, posto que não há inseticida comercial contendo a referida bactéria como ingrediente ativo.
