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.

Aside from bioinsecticides, such as derivatives of neem Azadirachta indica granella, Meliaceae Mancebo et al. Note First report of Hypsipyla grandella Lepidoptera: In Florida it is a rarely encountered specimen tree.

mahogany shoot borer – Hypsipyla grandella (Zeller)

Very likely, the increase in the selection pressure, exerted by extensive resistant monocultures may contribute to the reduction of resistance of Khaya ivorensis by H. Diel activity pattern and effects of wind on the mating success of cedar tip moth, Hypsipyla robusta Moore Lepidoptera: Their wood is used locally in numerous ways throughout the American Tropics, and they are planted as shade trees in urban areas of this region, but are present only as occasional specimen trees in Florida. Grwndella suggested that seed production is high enough to compensate for losses to the mahogany shoot borer.

Distribution Back to Top The distribution of the mahogany shoot borer coincides with that of its principal host plant species, mahoganies and cedros, found in southern Florida United Statesmost of the West Indies, Sinaloa and southward in Mexico, Central America, and South America, except Chile Griffiths Six pupae were formed, four which were female, with two presenting atrophied wings.

This principle has been applied in various silvicultural techniques with varying degrees of success, and research continues in this area LambMayhew and NewtonHauxwell et al. Therefore, the objective of this research was to determine the response of H.

The predominant soil is the Oxisol. Many authors have mentioned the damage to seeds by mahogany shoot borer, e. They undoubtedly are of varying degrees of importance in regulating populations of this insect, but their effect is insufficient to prevent economic damage. Also, regression and correlation analyses were performed to examine the relationships between temperature and the rates of development of immature stages and adult emergence.

Cedros are fast growing and are large trees at maturity.

Response to temperature was assessed by exposing H. Mature larvae are about 25 mm long.

The eggs of the mahogany shoot borer are oval and flattened and approximately 0. 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.


Studies have pointed out that some culture practices may reduce the damages such as pruning the affected branches and lateral shading Hilje hypsipyl Cornelius, ; Opuni-Frimpong et al.
