“…For example, Hebbar et al (69) showed that the proportton of comdia vs chlamydospores of F oxysporum erythoxzll, used to control coca, varies according to the composition of the growth medium, and, for the same medium, varies from one strain of F oxysporum to another Formulatton of mtcroorgatnsms as seed coating requires spectfic conditions to preserve the viability of the microorgamsms, and to enable then growth in accordance with seed germmatton.

Com o objetivo de avaliar o impacto sazonal de alguns inseticidas sobre predadores e parasitóides de pragas da cultura da soja, instalou-se um experimento com delineamento de blocos ao acaso, constando de oito tratamentos e três repetições, no campo experimental da Embrapa-Centro Nacional de Pesquisa de Soja, em Londrina, PR. Os tratamentos consistiram de aplicações de inseticidas para o controle da lagarta-da-soja (pulverizados em 21/1/93) e percevejos (4/3/93). A técnica empregada para levantamento da população de insetos foi a do método do choque, que consiste na aplicação de um inseticida de alto impacto sobre a comunidade de insetos presente nas plantas, sua coleta sobre panos estendidos no solo, e sua posterior identificação e contagem em laboratório. A análise da variância revelou não haver diferenças significativas entre as populações de predadores, himenópteros e dípteros encontrados, nos diferentes tratamentos estudados. Também não foram verificados os fenômenos de ressurgência de pragas ou o aparecimento de elevadas populações de pragas secundárias.

Pear cultivation accounts for a large proportion of worldwide orchards, but its sustainability is controversial because it relies on intensive use of pesticides. It is therefore crucial and timely to find alternative methods to chemical control in pear orchards. The psyllids Cacopsylla pyri and Cacopsylla pyricola are the most important pests of pear trees in Europe and North America, respectively, because they infest all commercial varieties, causing damage directly through sap consumption or indirectly through the spread of diseases. A set of natural enemies exists, ranging from generalist predators to specialist parasitoids. Trechnites insidiosus (Crawford) is undoubtedly the most abundant specialist parasitoid of psyllids. In our literature review, we highlight the potential of this encyrtid species as a biological control agent of psyllid pests by first reviewing its biology and ecology, and then considering its potential at regulating psyllids. We show that the parasitoid can express fairly high parasitism rates in orchards, and almost perfectly matches the phenology of its host and is present early in the host infestation season, which is an advantage for controlling immature stages of psyllids. We propose new research directions and innovative approaches that would improve the use of T. insidiosus in integrated pest management strategies in the future, regarding both augmentative and conservation biocontrol. We conclude that T. insidiosus has many advantages and should be included as part of integrated biological control strategies of pear psyllids, along with predators, in‐field habitat conservation, and the rational use of compatible chemicals. © 2021 Society of Chemical Industry.
