This is the first report of the parasitoid Lysiphlebus testaceipes (Cresson) as a biological control agent of the aphid Aphis gossypii Glover in watermelon crop in Vale do Açu, RN. It was observed that near the harvest, almost all collected aphids were mummified, and after analyzing the emerged parasitoids, the parasitoid L. testaceipes was identified. Therefore, in the future, this species may be included in A. gossypii integrated management programs.

Este estudio tiene como objetivo evaluar el potencial regulador de Lysiphlebus testaceipes y Aphidius matricariae sobre Aphis gossypii en condiciones de laboratorio semiáridas. Nuestros resultados mostraron que la longevidad de las hembras de L. testaceipes fue significativamente menor que la de A. matricariae. El porcentaje diario de momificación fue más importante para L. testaceipes que para A. matricariae y disminuyó con la edad de los parasitoides. En general, las tasas de momificación y de emergencia fueron más altas en L. testaceipes. La descendencia de A. matricariae se desarrolló en menos tiempo que la de L. testaceipes. La proporción sexual no varió respecto a las especies parasitoides. Con nuestros resultados, L. testaceipes fue más efectivo para el control biológico de A. gossypii en patata en agro-ecosistemas semiáridos. This study aims to evaluate the regulatory potential of Lysiphlebus testaceipes and Aphidius matricariae over Aphis gossypii in semiarid laboratory conditions. Our results showed that the longevity of L. testaceipes females was significantly lower than A. matricariae ones. The daily mummification rate of aphid was more important for L. testaceipes than for A. matricariae and declined with parasitoids age. Overall, both the mummification rates and the emergence rates were the highest in L. testaceipes. A. matricariae offspring developed in a shorter time compared to L. testaceipes ones. The overall sex ratio did not vary according to parasitoid species. From our results L. testaceipes was more effective for the biological control of A. gossypii on potato in the semi-arid agro-ecosystems.

<p>To determine selective effectiveness for specific pesticides on biological control species, we evaluated the contact toxicity of different treatments including 10 ml l<sup>-1</sup> dishwashing liquid, Dayabon 5, 6, 7, 8, 9 and 10 ml l<sup>-1</sup>, Palizin 1.5, 2.5 and 2.5 ml l<sup>-1</sup>, Palizin 1.5, 2 and 2.5­+­Citrol oil 5 ml l-1, Tondoxir 2 and 3­+­Bartar soap 1 ml l<sup>-1</sup>, Malathion 2 ml l<sup>-1</sup> and control (water) on the adult aphids of the most important citrus gardens and their predator, <em>Coccinella septempunctata </em>L. in the laboratory conditions. The results revealed that the Palizin treatment 2.5­+­Citrol oil 5 ml l<sup>-1</sup>, caused the highest rate of the mortality of the citrus green aphid, <em>Aphis spiraecola </em><a title="Edith Marion Patch" href="https://en.wikipedia.org/wiki/Edith_Marion_Patch">Patch</a>, 1914 in 36 hours. Concentrations of 7 to 10 ml l<sup>-1</sup>, Dayabon and Palizin 2.5­+­Citrol oil 5 ml l<sup>-1</sup>, as well as 3 ml<sup>-1</sup> Tondexir + Bartar soap 1 ml<sup>-1</sup> had the highest mortality of the citrus brown aphid, <em>Aphis citricidus </em>(Kirkaldy, 1907), 36 hours after treatment (100 %). In addition, the treatments of Palizin 2 ml<sup>-1</sup>­+ Citrol oil of 5 ml<sup>-1</sup>, as well as 2 ml l<sup>-1</sup> Tondexir­+­Bartar soap 1 ml l<sup>-1</sup> and concentrations of 5 ml l<sup>-1</sup> and 6 ml<sup>-1</sup> of Dayabon produced the same amount of the mortality of the citrus black aphid, <em>Toxoptera aurantii </em>(Boyer de Fonscolombe, 1841). Tondexir 3 ml l<sup>-1</sup>­+­Bartar soap 1 ml l<sup>-1</sup> in 24 hours after treatment caused the highest rate of the mortality of the cotton aphids, <em>Aphis gossypii </em>Glover, 1877 (83.88 %). Malathion treatment caused a 100 % mortality of the predator ladybird 36 hours after treatment, while the lowest amount was observed in the Dayabon at 10 ml l<sup>-1</sup> with 33.34 % mortality.</p>

And Behavior

Chemical control remains the main method of controlling the cotton aphid (Aphis gossypii Glover). Millions of dollars have been lost due to plant damage which resulted in reduced quality and yield of cotton. Nevertheless, A. gossypii can rapidly develop resistance to different groups of insecticides such as organophosphates, carbamates and pyrethroids. The potential of Huwa-San TR50 in controlling A. gossypii is yet to be tested. Huwa-San TR50 is a formula of hydrogen peroxide which has been stabilized by the addition of a small quantity of silver and has extensively used as a disinfectant. In this study, it was found to be very potent in killing A. gossypii and produced 93.5, 96.5, 97 and 95.5% mortality at 1000, 2000, 3000 and 4000 ppm, respectively, after 48 h of exposure. Furthermore, there was no significant difference between four Huwa-San TR50 concentrations after 48 h of exposure, on the mortality of A. gossypii. Huwa-San TR50 of up to 4000 ppm had no observable effects on the mortality and behavior of adult honeybee workers (Apis mellifera lamarckii) as compared with the control. Also, Huwa-San TR50 concentration of up to 3000 ppm had no observable effect on seven-spot ladybird beetles (Coccinella septempunctata) whereas a concentration of 4000 ppm produced 100% mortality after 24 h of exposure. Huwa-San TR50 concentrations of up to 2000 ppm failed to produce any symptoms on cucumber leaves. The differential effects of Huwa-San TR50 on aphids and beneficial insects, suggest the need for further investigation to understand the effects of Huwa-San TR50 on other host plants of aphids and aphid species.
