Reduction in damage to mahogany shoot borer and mahogany leaf miner by use of azadirachtin. Pupal mortality was generally high. The silviculture of mahogany.

The insect’s most severe damage to trees occurs when a larva bores into and kills the terminal shoot. Literature Cited Becker, V. The eggs are deposited during the early morning hours on leaf scars, new shoots, leaf veins and fruits.

Hypsipyla grandella – Wikipedia

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. They attack a higher percentage of mahoganies grown in plantations than trees interspersed in natural forests, and this insect has been a major impediment to the establishment of mahogany plantations.

DeFilippis, University of Florida. Each pupa was weighed using an analytical scale and sexed Hidalgo-Salvatierra to determine sex ratio.

Cumulative emergence at these temperatures was best described by logarithmic curves with decreasing increments over time Fig. 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.

The eggs incubate for three to five days, depending on ambient temperature Grijpma In order to determine mating success, females were dissected to count the number of spermatophores in their bursa copulatrix, as each one of them represent a successful mating Lara EntwistleBecker Some meliaceous tree species that are native to the tropics of the Eastern Hemisphere are attacked by mahogany shoot borer Hypsipyla grandella when grown as exotics in the Americas; in their native ranges they are generally hosts of this insect’s Eastern Hemisphere counterpart, Hypsipyla robusta.
