Developmental response of the mahogany shootborer, Hypsipyla grandella ( Zeller), to temperature was determined in laboratory trials in Turrialba, Costa Rica. The mahogany shoot borer, Hypsipyla grandella,is one of the most of Female and Male Hypsipyla grandella (Zeller) to Swietenia macrophylla Essential Oils. J Chem Ecol. Sep;29(9) Electrophysiological responses of female and male Hypsipyla grandella (Zeller) to Swietenia macrophylla essential oils.

graandella Literature Cited Becker, V. This may be explained by the higher levels of food storage normally present in the fat body tissue of the female Chapman Ecology and Perspectives on Management.
Its ecology and management. The hollow shoot dies and buckles, and the leaves of this twig die. The hind wings are white to hyaline with dark colored margins Figure 2. Development of Hypsipyla grandella Zeller Lepidoptera: It can be determined whether a larva is actively boring in a twig by the appearance of the expended frass, as this is compact and relatively light colored when fresh, becoming darker and disintegrating after the larva is no longer feeding Howard The impact of this insect on regeneration should be investigated further.
Management Back to Top Research efforts to develop management methods have been much greater for mahogany shoot borer as a pest zellet timber trees rather than as ornamental or shade trees LambGrijpmaNewton et al.
Under such conditions they are less likely zller be attacked by mahogany shoot borers. Development rate was highest for eggs 1. Cumulative emergence at these temperatures was best described by logarithmic curves with decreasing increments over time Fig.
Reduction in damage to mahogany shoot borer and mahogany leaf miner by use of azadirachtin. Chevallierboth important meliaceous timber trees of the Eastern Hemisphere tropics that are heavily attacked by Hypsipyla robusta when growing there, were not attacked by Hypsipyla grandella when grown in Costa Rica Grijpma Nine additional species of Hypsipyla have been described.

RB, Hauxwell C eds. The hind wings are white to hyaline with dark hypsipya margins. The seasonal abundance and feeding damage of Hypsipyla grandella Lepidoptera: Recent reviews of Hypsipyla shoot borers include Newton et al.
The mahogany shoot borer, Hypsipyla grandella Zellerbores into the twigs and seed capsules of trees in the mahogany family Meliaceaeespecially mahogany species Swietenia spp. Because the first instar larvae may feed on surface tissues 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.
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. They undoubtedly are of varying degrees of importance in regulating populations of this insect, but their effect is insufficient to prevent economic damage. They are generally laid singly but may sometimes be aggregated into clusters of three to four eggs in or near leaf-axils.
Only a percentage of the growing shoots on a tree are attacked, the damage to the twigs is not conspicuous from a distance, and growth of branches during the summer conceals the damage. The pupal stage takes place inside the hollowed twig or in the seed capsule, or in the leaf litter or soil under host trees.
The body of the early instar larva is tan to white in color, becoming bluish in later instars. All the contents of this grandekla, except where otherwise noted, is licensed under a Creative Commons Attribution License.

Development of Hypsipyla grandella Zeller Lepidoptera: For instance, available information on the H. Also, the damage to the terminal shoot breaks apical dominance, resulting in excessive lateral branching.
Integrated pest management of Hypsipyla spp. However, these experiments failed, because pairs of H. Pyralidae en condiciones de laboratorio. This fact coincided with findings from previous authors Larawho reported that during copulation the male inserts a single spermatophore.
Supernumerary instars have been reported for H.
