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.

Becker granddlla that seed production is high enough to compensate for losses to the mahogany shoot borer. For determining development time, a cohort of fresh eggs less than 24h hypsiypla was placed individually inside 30 ml glass flasks containing a disk of C. The mahogany shoot borer, Hypsipyla grandella Zellerbores into the twigs and seed capsules of trees in the mahogany family Meliaceaeespecially mahogany species Swietenia spp.
Howard and Meerow On the other hand, Australian red-cedar Toona ciliata [Roemer] var.
The color of the eggs changes from white to red within the first 12 hours after oviposition. Silvicultural management of Hypsipyla spp. It was also emphasized that vigorous grandela of young trees should be promoted by cultural methods in the nursery and in young plantations. Observaciones sobre el ciclo de vida de Hypsipyla grandella Zeller en Barinitas, Venezuela.
True mahoganies are perhaps the most important tropical timber trees in the hypsjpyla. Mahogany shoot borer attack reduces the grade and thus the monetary value of young mahoganies grown in nurseries for use as ornamentals, their chief use in Florida Howard and Meerow These values allowed calculation of the lower thermal threshold for each stage: West Indies mahogany S.
Research in resistance of mahoganies to Hypsipyla species. West Indies mahogany, Swietenia mahagonifoliage and seed capsules. Agricultural and Forest Entomology 4: The eggs incubate for three to five days, depending on ambient temperature Grijpma The middle to outer areas of the forewings appear dusted with whitish scales with black dots toward the wing tips.
Moth Photographers Group – Hypsipyla grandella –
The former is distributed throughout the neotropics, whereas H. University of Washington, Seattle, 77p. Timbers of the New World.
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. The pupa was subsequently transferred to a dry, 30ml plastic flask, where it was inspected daily until adult emergence.
The pupae of Hypsipyla grandella are brownish-black in color and enclosed in a silken cocoon.
mahogany shoot borer – Hypsipyla grandella (Zeller)
This may be true in Florida, where the mahogany shoot borer attacks twigs mostly in spring, and thus chemical applications can be concentrated during this period. Current status of the taxonomy of Hypsipyla Ragonot Pyralidae: Wylie reviewed published information on chemical control of Hypsipyla spp. Thermal constants were estimated for each temperature Table 3and a general constant of degree-days was calculated.
In the case of H. Participants of an international workshop on Hypsipyla shoot borers in concluded that the most promising management strategies hypsipypa these pests involved identification and use of resistant genotypes and planting mahogany and cedro trees in mixed stands under an established canopy. The adults of Hypsipyla grandella are brownish to grayish-brown in color with a wingspan measuring about 23 to 45 mm.

Wing veins hypsiphla distinctively overlaid with black. Relationships between these variables and temperature were analyzed by means of ANOVA, regression and correlation procedures. Mahogany trees are susceptible to attack when they reach a height of 0. Day-degree methods for pest management. West Indies mahogany, Swietenia mahagoniseed capsule damaged by mahogany shoot borer, Hypsipyla grandella Zeller. On the relationship between temperature and rate of development of insects at constant temperatures.
Hosts Back to Top Species of several genera in the botanical family Meliaceae can serve as hosts of the mahogany shoot borer, including CarapaCedrelaGuareaKhayaSwieteniaand Trichilia EntwistleBecker The hollow granddlla dies and buckles, and the leaves of this twig die. West Indies mahogany, Swietenia mahagoniundergoing spring flush. Journal of Tropical Forest Science 6: The hind wings are white to hyaline with dark colored margins.
There they hollow out seeds, after which they bore into the capsule’s core, where they sometimes pupate. Cumulative emergence at these temperatures was best described by logarithmic curves with decreasing increments over time Fig. Small trees whose terminal shoots are attacked repeatedly in successive years become extremely deformed.
