Biology and reproductive parameters of Diaphorina citri (Hemiptera: Liviidae) in different Rutaceae hosts.

Pérez Artiles, Lumey A. | 2017-12-30

This work aimed to study the biology and population parameters of Diaphorina citri in Rangpur and Citrumelo ‘Swingle’ rootstocks and in their combinations with orange scions in Araraquara, Sao Pablo. For the maintenance of a D. citri breeding stock, plants of Murraya exotica L. were used. In each treatment the duration of the biological stages of the pest, viability of the eggs, survival of egg to adult and sexual ratio were evaluated. Egg to adult development time ranged from 15.08 days in Pera / Rangpur to 16.5 days in Hamilim / Citrumelo ‘Swingle’. The highest viability of eggs (82.02 %) of D. citri was observed in the Valencia / Rangpur combination and the lowest in Hamilim / Citrumelo ‘Swingle’ (73.66 %). The egg-adult survival values ranged from 56.16 to 71.07 %, obtaining the lowest survival values in the Hamilim / Citrumelo ‘Swingle’ combination. The lowest mean oviposition (eggs for female) was observed in Citrumelo ‘Swingle’ (185.10). Based on the fertility chart, Rangpur had the highest net reproductive rate (Ro = 160.57) and the shortest generation time (31.54 days). The intrinsic growth rate was higher in the Valencia/Rangpur combination (0.1517). A positive and significant correlation was found between total oviposition and female longevity (R = 0.23440; P = 0.03649) and between the former variable and duration of oviposition period (0.39011, P = 0.0003). Citrumelo ‘Swingle’ and Hamilim / Citrumelo ‘Swingle’ were the treatments that most negatively affected the biological parameters studied mainly oviposition and survival

Biology of Diaphorina citri (Hemiptera: Liviidae) under glass house conditions in Palmira, Colombia.

García, Yesenia | 2016-06-30

In this study, the morphological characteristics of each stage of development, duration, survival, ecological parameters, reproductive capacity, longevity of adults, and stage-specific mortality of Diaphorina citri (Hemiptera: Liviidae) were determined. It was conducted in a greenhouse (maximum temperature: 37.1 ± 5.1 °C, minimum temperature: 25.0 ± 2.0 °C; maximum relative humidity: 67.0 ± 6.2%, minimum relative humidity: 39.5 ± 10.9%; 12: 12 h Light: Dark, natural light conditions) in the municipality of Palmira, Valle del Cauca. Mean time from egg to adult was 15.41 ± 0.49 days. The median survival time for females was 48.25 days and 50 days for males. The survival rate to adult stage of D. citri was 6.86% with the highest mortality rate recorded for first-instar nymphs (81%). Females oviposited an average of 237 eggs during their reproductive cycle. A dichotomous key, an essential tool for conducting biological studies, is provided to separate the different growth stages of the Asian citrus psillid. Studies on the biology of D. citri will serve as a baseline for the mass rearing of its parasitoid, T. radiata.
