| description | The eucalyptus gall wasp Leptocybe invasa, is an Australian native pest that affects plantations of Eucalyptus spp. E. camaldulensis is the most susceptible host; worldwide it is used for sawn wood and pulp or used as urban tree in many Mexican cities. The exotic nature of L. invasa and its development in galls, impedes its natural regulation for native entomophagous in Mexico, which represents a threat for the producing regions of eucalyptus and urban areas. Thus, the present study evaluated the efficiency of insecticides in greenhouse conditions, by means of soil and foliar applications, on the immature stages: egg, young larva, mature larva and pupa, using plants of E. camaldulensis less than one year old. Major mortality was registered in egg (35% to 79%) and young larva (40% to 75%) when Carbofuran or Imidacloprid was applied to the soil. The efficiency of these products diminished (mortality < 5%) in the stages of mature larva and pupa. The application of Spirotetramat stood out in the application on leaves, but it is not enough on its own to control the plague (mortality < 40%). Based on the results of this investigation, and previous studies published in the specialized literature, it is suggested that chemical management on L. invasa in greenhouses is feasible but only as an emergency measure. This, using Carbofuran or Imidacloprid in application to the soil, alternating with an application on the leaves after Spirotetramat. |

La avispa agalladora del eucalipto, Leptocybe invasa, es una plaga de origen australiano que afecta a plantaciones de Eucalyptus spp. La especie Eucalyptus camaldulensis es el más susceptible hospedero y es ampliamente utilizado en el mundo para madera aserrada, pulpa y carbón; inclusive, es parte del arbolado urbano, como ocurre en varias ciudades de México. La naturaleza exótica de L. invasa y su desarrollo en agallas, dificulta su regulación natural por entomófagos nativos en este país, lo que representa una amenaza para las regiones productoras de eucaliptos y áreas urbanas. El presente estudio evaluó la eficiencia de insecticidas en condiciones de invernadero, mediante aplicación al suelo y foliar, sobre los estados inmaduros de la avispa: huevo, larva joven, larva madura y pupa, utilizando plantas de E. camaldulensis menores de un año. La aplicación de Carbofurán o Imidacloprid en suelo ocasionó mayor mortalidad en huevo (35% a 79%) y larva joven (40% a 75%), mientras que en larva madura y pupa causó una mortalidad baja (< 5%). La aplicación de Spirotetramat sobresalió en las aplicaciones foliares, pero no es suficiente por sí sola para controlar a la plaga (mortalidad < 40%). Con base en los resultados de esta investigación y los antecedentes de la literatura especializada, se sugiere que el manejo químico sobre L. invasa en invernaderos es factible pero solamente como medida emergente. Esto mediante la utilización de Carbofurán o Imidacloprid en aplicación al suelo alternado con una aplicación foliar posterior de Spirotetramat.
