El mexicano enano libro pdf1/1/2023 ![]() ![]() Hatching occurred between late May and mid-December, giving a wide range of egg development of 100–326 days. ![]() Potential fecundity based on counts of mature oocytes in females was 278.5☘8.5. Nearly all newly eclosed adult females had no developed oocytes. Peak dates for emergence and oviposition varied with year from 13 January to 4 February and from 31 January to 17 February, respectively. Most adults emerged between early January and late February, with males emerging before females. Fifth instar nymphs constructed vertical pre-emergence burrows ending 45☒0 mm (mean±one standard deviation) from the soil surface from mid-December to early January. Life-history data were collected in kiwifruit orchard blocks during 2004–2013 with the aim of informing future studies on the biology and management of chorus cicadas. Studies on the insect’s biology are suggested for integral management plans.Ĭhorus cicada Amphipsalta zelandica (Boisduval) is an endemic species that is widespread in native and exotic forest and in some horticultural crops. bulgara, which represents a loss of fruit in productive trees. Findings/Conclusions: This study quantifies for the first time the direct and indirect damage caused by oviposition of the cicada D. The highest number of mummified fruits (15.6) was observed in Colimex (density of 312 trees ha-1) and the estimation that up to 146 kg of fruit could be lost. A significant relationship was determined between the number of eggs and the damage length and flow diameter (<0.05). The greatest number of eggs was observed in Persian lime (371). The lowest number of eggs was 26 in flow one in Mexican lime without thorns, while the highest was 171 in Mexican lime without thorns. The second flow showed the highest frequency of damage (32%), while the lowest frequency was obtained in the first flow (17.3%). The trees of largest size showed a higher percentage of affected flows. Results: The damage ranged between 78.6% (Mexican without thorns) and 94% (Colimex). The loss of fruit from the indirect effect (kg ha-1), was estimated in three densities of Colimex and Lise. In each plot, 15 trees were selected randomly to evaluate the variables: height, crown diameter, damaged growth flows, damaged growth diameter, damage length, and number of eggs. bulgara was calculated by counting nests in trees of five lime cultivars (Persian, Mexican with thorns, Mexican without thorns, Colimex and Lise). Design/Methodology/Approach: The damage caused by D. ![]() Objective: To quantify the direct and indirect damage caused by Diceroprocta bulgara in lime cultivars: Persian, Mexican with and without thorns, Colimex and Lise on the Coast of Oaxaca, Mexico. ![]()
