Developmental response of the mahogany shootborer, Hypsipyla grandella ( Zeller), to temperature was determined in laboratory trials in Turrialba, Costa Rica. ABSTRACT. The mahogany shoot borer Hypsipyla grandella Zeller is an important economic pest in all American tropical forests, because it prevents. The mahogany shoot borer Hypsipyla grandella (Zeller) is one of the worst neotropical forest pests. Currently there is no control method that.

The monoculture of exotic species like Khaya spp. Materials and Methods Study Site. Hilje and Cornelius, and other shrubby crop species Paul and Weber, ; avoidance of shallow soils, with high acidity and deficient drainage Hilje and Cornelius, Cedro hembra, Spanish cedar, pp.
It is estimated that there are producers that cultivate about 15 thousand hectares of Khaya ivorensis A. Intercropping Cedrela odorata with shrubby crop species to reduce infestation with Hypsipyla grandella and improve the quality of timber. Integrated pest management of mahogany shoot borer in nurseries in Florida where mahoganies are grown for use as shade trees should involve methods of reducing pest populations during spring and pruning methods that promote recovery of trees that are attacked.
It was also emphasized that vigorous growth of young trees should be promoted by cultural methods in the nursery and in young plantations. 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 Pyralidae in a mahogany stand, in Turrialba, Costa Rica.
Mahogany of Tropical America.
mahogany shoot borer – Hypsipyla grandella (Zeller)
Mahogany shoot borer, Hypsipyla grandella Zellerlarva. Pesquisa Florestal Brasileira I agree to the terms and conditions.
Seasonal incidence of shoot infestation by mahogany shoot borer in Florida. This is one of the most popular shade trees in urban areas of southern Florida, and is a component of natural forests in the Everglades and the Florida Keys. Because the first instar larvae may feed on surface grnadella for a brief period before boring into the twig or fruit Ramirez Sanchezit is theoretically possible to reduce populations of mahogany shoot borer by topical applications of a pesticide or an antifeedant.
Mahoganies established in the landscape are also commonly attacked by mahogany shoot borers, mostly in the spring, but the damage does not noticeably affect growth or aesthetic quality of mature trees.
Forest Ecology and Management Flasks were turned upside down and each egg was placed above the disk. Although there has been some interest in such techniques as augmentation of natural enemy populations, biological control of the mahogany shoot borer does not seem a promising option reviewed by Sands and Murphy Desenvolvimento de Hypsipyla grandella Zeller Lepidoptera: Influence of flight on the mating behavior of the mahogany shootborer Hypsipyla grandella Zeller Lepidoptera: Temperature greatly influenced the development time of immature stages egg, larva and pupa of H.
Mating Behavior of Hypsipyla grandella Lepidoptera: The average annual temperature is Pentatomidae feeding on cotton and soybean reproductive structures.
The forest species of Meliaceae family, native to Tropical America, is largely explored due to the high commercial value of its timber. In the case of H. This fact has been reported in Hypsipyla robusta attacking the American mahogany Switenia macrophyla cultivated in Africa and Australia Newton et al. These trends also held for each sex. It is presently the main source of mahogany wood. Under such conditions they are less likely to be attacked by mahogany shoot borers.
Supernumerary instars have been reported for H. Furthermore, it precludes using degree-day approaches WigglesworthPruess to predict field population peaks of this pest, in order to improve timing for application of management tactics.
Damage Back to Top Hypzipyla trees are susceptible to attack when they reach a height of 0. Research to identify genetic strains of these trees that are resistant or that can overcome shoot borer attack has progressed well Mayhew and NewtonWatt et al.
Ecology and Perspectives on Management. Mahogany shoot borers attack new shoots and are seldom seen attacking hardened-off shoots.

Development of Hypsipyla grandella Zeller Lepidoptera: Services on Demand Journal. Their major use is as cabinet woods.
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 Results and Discussion Six pupae were formed, four which were female, with two presenting atrophied wings. For determining development time, a cohort of fresh eggs less than 24h old was placed individually inside 30 ml glass flasks containing a disk of C.

Current status of the taxonomy of Hypsipyla Ragonot Pyralidae: Thirty-six papers on these insects are published in the proceedings of a workshop entitled Hypsipyla shoot borers in Meliaceae Floyd and Hauxwell Studies on shoot borer Hypsipyla grandella Zeller Lep, Pyralidae: In Florida it is a rarely encountered hypskpyla tree.
The former is distributed throughout the neotropics, whereas H. A piece of paper towel was fastened with the lid and was moistened periodically.
