In southern Florida, where the flush of new growth of West Indies mahogany takes place from April to June Howard and Solismahogany shoot borers attack shoots from early spring to mid-summer, with pronounced peaks in May Howard In fact, the most important damage of the insect, destruction of the terminal shoot, is the result of a single larva per tree. This is the first report of H.

Nevertheless, the information gathered at constant temperatures in environmental chambers allowed us to estimate a common lower thermal threshold grandlela all H. The body of the early instar larva is tan to white in color, becoming bluish in later instars. Average duration of the pupae stage is 10 days Ramirez Sanchez Observaciones sobre el ciclo de vida de Hypsipyla hypsipyoa Zeller en Barinitas, Venezuela.

Encontramos que los machos y hembras realizan un comportamiento de aleteo hypspiyla y aleteo largo. Hypsipyla grandella Zeller Insecta: The shoot borer damages several tree structures, especially the apical shoots, impairing the formation of the commercial stem.
This prevents the monoculture establishment of native Meliaceae. Desenvolvimento de Hypsipyla grandella Zeller Lepidoptera: A female may lay about eggs, but typically lays no more than a few eggs per tree Solomon Pyralidae in seed capsules of Swietenia mahagoni in Florida.
Evaluation of four Taungya permanent big-leaf mahogany plots, aged 36 to 38 years, in Belize. Temperature greatly influenced the development time of immature stages egg, larva and pupa of H. Some contact insecticides that are effective against other twig borers have been field tested to reduce hyspipyla by mahogany shoot borer without success.
The impact of this insect on regeneration should hhpsipyla investigated further.

Development of Hypsipyla grandella Zeller Lepidoptera: Further research must be encouraged concerning monitoring, pest control techniques, selection of new resistant materials and resistance management strategies, such as the use of structured refuge with susceptible materials. Cumulative emergence at these temperatures was best described by logarithmic curves with decreasing grandekla over time Fig. Mahogany shoot borers attack new shoots and are seldom seen attacking hardened-off shoots.

Use of grafiting to prevent Hypsipyla grandella Zeller Lepidoptera: Eggs were inspected every 24h, in order to determine hatching rates and development time at each constant trandella.
Management Back to Top Research efforts to develop management methods have been much greater for mahogany shoot borer as a pest of timber trees rather than as ornamental or shade trees LambGrijpmaNewton et al. This can be explained because high temperatures constrain insect development either by protein denaturing or because of accumulation of toxic wastes resulting from metabolic imbalances Chapman Books on mahogany with discussions of insects associated with them include Lamb and Mayhew and Newton The region is under the Cerrado domain and has plain relief.
