It is appreciated for its physical characteristics and, therefore, its native specimens are overexploited.&lt;/span&gt;&lt;/span&gt;&lt;span class=&quot;normalchar&quot;&gt;&lt;span lang=&quot;EN-US&quot;&gt;Commercial cultivation initiatives have been continuously flawed as a result of the damage caused by &lt;a name=&quot;_Hlk533076942&quot;&gt;&lt;/a&gt;mahogany shoot borer &lt;em&gt;Hypsipyla grandella &lt;/em&gt;(Zeller, 1848).&lt;/span&gt;&lt;/span&gt;&lt;span class=&quot;normalchar&quot;&gt;&lt;span lang=&quot;EN-US&quot;&gt;Planting under shaded sites has been one of the management methods used to reduce insect attacks. However, the reason why mahogany shoot borer does not attack shaded plants as often is still unknown. Therefore, the aim of this research was to find cultivation parameters that could combine proper plant development and low rate of&lt;/span&gt;&lt;/span&gt;&lt;span class=&quot;normalchar&quot;&gt;&lt;span lang=&quot;EN-US&quot;&gt;attacks by&lt;em&gt; Hypsipyla grandella&lt;/em&gt;.&lt;/span&gt;&lt;/span&gt;&lt;span class=&quot;normalchar&quot;&gt;&lt;span lang=&quot;EN-US&quot;&gt;For this purpose, increases in height and shoot diameter of cedar seedlings, planted in agroforestry systems, were monitored for the two first years. Three canopy cover rates, namely, 0-20%, 20-40% and 40-60%, were tested for plant development and&lt;/span&gt;&lt;/span&gt;&lt;span class=&quot;normalchar&quot;&gt;&lt;span lang=&quot;EN-US&quot;&gt;frequency of&lt;/span&gt;&lt;span lang=&quot;EN-US&quot;&gt; attacks by&lt;/span&gt;&lt;/span&gt;&lt;span class=&quot;normalchar&quot;&gt;&lt;em&gt;&lt;span lang=&quot;EN-US&quot;&gt;Hypsipyla grandella&lt;/span&gt;&lt;/em&gt;&lt;span lang=&quot;EN-US&quot;&gt;. &lt;/span&gt;&lt;/span&gt;&lt;span lang=&quot;EN-US&quot;&gt;The adult population of the insect was monitored with semiochemicals throughout the experimental period, and two pheromonal blends and one food bait were tested. Field results showed that one of the pheromone blends was efficient in identifying small variations in the population of adult specimens. Regarding to the plant development, the treatment with the highest cover rate showed the lowest parameters compared to the intermediate cover&lt;/span&gt;&lt;span class=&quot;normalchar&quot;&gt;&lt;span lang=&quot;EN-US&quot;&gt;. &lt;/span&gt;&lt;span lang=&quot;EN-US&quot;&gt;The frequency of attacks by&lt;/span&gt;&lt;/span&gt;&lt;span class=&quot;normalchar&quot;&gt;&lt;em&gt;&lt;span lang=&quot;EN-US&quot;&gt;Hypsipyla grandella&lt;/span&gt;&lt;/em&gt;&lt;span lang=&quot;EN-US&quot;&gt; was greater in the treatment with the lowest cover (0-20%).&lt;/span&gt;&lt;/span&gt;&lt;span class=&quot;normalchar&quot;&gt;&lt;span lang=&quot;EN-US&quot;&gt;The results suggest that in canopy cover, ranging from 20 to 40%, good rates of initial development of plants can be combined with low frequency of attack by&lt;/span&gt;&lt;/span&gt;&lt;span class=&quot;apple-converted-space&quot;&gt;&lt;span lang=&quot;EN-US&quot;&gt; &lt;/span&gt;&lt;/span&gt;&lt;span class=&quot;normalchar&quot;&gt;&lt;em&gt;&lt;span lang=&quot;EN-US&quot;&gt;Hypsipyla grandella&lt;/span&gt;&lt;/em&gt;&lt;span lang=&quot;EN-US&quot;&gt;.&lt;/span&gt;&lt;/span&gt;}, number={3}, journal={Ciência Florestal}, author={Borges, Rafael and Boff, Mari Inês Carissimi and Blassioni-Moraes, Maria Carolina and Biscaro-Borges, Camila and Mantovani, Adelar}, year={2019}, month={set.}, pages={1324–1332} }
