Aphis Craccivora Koch. And Predators on Faba Bean and Cowpea in Newly Reclaimed Areas in Egypt

The current investigation was performed to assess the effectiveness of predators as biocontrol agent against Aphis craccivora and Myzus persicae on broad bean field. Aphis craccivora had three peaks of abundance during the fourth week of December, first week of February and March of 2020-202 season (632, 901 and 671 individuals / 25 leaves). While it had two peaks during the second week of January and February of 2021/2022 (914 and 1085individuals/25 leaves). Meanwhile, M. persicae had two peaks of abundance (498 and 542 individuals/25 leaves) in 2020-21 and three peaks (689, 608 and 434 individuals/25 leaves) in 2021-22. The common predators caught in the broad bean fields were: Coccinella undecimpunctata L., Chrysoperla carnea Steph., Cydonia vicina isis (Muls.), Scymnus sp., Metasyrphus corollae F. and Orius sp. These predators recorded two peaks (50 and 52 predators/ 25 leaves) during the first season, and three peaks during the second season (40, 44 and 39 predators / 25 leaves) on broad bean. Biology of C. carnea on Aphis craccivora and Myzus persicae were examined at 26 ± 1°C and 70 ± 5% R.H. The total developmental time of C. carnea (egg hatching to adult exclusion) was 18.59 ± 0.43 and 23.54 ± 0.55 days when fed on A. craccivora and M. persicae, respectively. The mean number of eggs per C. carnea female was 345.83 ± 5.11 and 489.0 ± 6.58 eggs females fed on A. craccivora and M. persicae during their larval stage, respectively.

“…Saleh et al (2009) reported that temperature and relative humidity play an important role in the population changes of A. craccivora on the broad bean crop. However, Ali et al (2013) recorded a highly positive significant correlation between the number of A. craccivora on cowpea and both temperature and relative humidity but not on broad beans in Khattara district, Sharkia. Also, the relatively warmer temperatures recorded in some years positively influenced the population development of R. maidis in cereals (Barta and Cagan, 2005).…”

“…In Egypt, biological, ecological and taxonomical studies concerning spiders as predators of aphids (El-Heneidy & Abbas, 1984;El-Hennawy, 1992 andAbo-zaed et al, 2018) still need further investigations to determine which species can be used as biological control agents. Also, in spite of the available literature on the ecological studies on aphids and their associated enemies, many were not concerned with spiders or identifying the species and families of the associated predatory spiders (Mannaa, 2000;Ali et al, 2013 andTambe andKadam, 2015).…”

Infestation of the broad bean and maize crop with Aphis craccivora and Rhopalosiphum maidis, respectively at Qaha research station, Qalubyia started in January and May (or June) during two years of study. The monthly collected number and percent abundance of each and total life stage (s) of A. craccivora and R. maidis gradually increased to reach peaks in March (or March and February) and August then decreased in the last month of the season of the broad bean and maize, respectively. Immatures were the most prevalent life stages followed by unwinged and winged adult females. Generally, the total collected number of each life stage of A. craccivora and R. maidis was higher in 2018 than in 2017.A total of 26 spider species belonging to 20 genera and 10 families of order Araneae were associated with the two aphids, A. craccivora and R. maidis, on the broad bean and maize at the site of study in 2017 and 2018. About 50% of the collected species were common spiders associated with each of the two aphid species on its host crop. Generally, the total spiders of the collected families on the broad bean and maize crops started appearing with relatively small numbers in January and May, gradually increased in parallel with those of the associated aphid species to reach peaks in March and August, then the numbers of both were decreased at the end of the crop season in April and September, respectively during each year of the study.

Field experiments were conducted at Kafr El-Sheikh governorate, Egypt, in 2020-2021 and 2021-2022 seasons to study the population dynamics of certain insect pests infesting faba bean plants namely Liriomyza trifolii (Burgess); Aphis craccivora (koch) and Empoasica spp. In addition, the impacts of certain weather and biotic factors on the population density of the previously mentioned pests. Liriomyza trifolii population density increased in January and March (7.5 and 8.2 larvae/25 leaflets) in 2021 and 2022, respectively. The highest population of nymphs and adults of Empoasca spp in the first season were 6.8 individuals on the 20 th of February, while, in the 2022 season the population density was higher at the end of the season during April and recorded 18 individuals/ 5 plants. For results of the simple correlation in 2021 season, Liriomyza trifolii insects were insignificant with the weather, and biotic factors, whereas, in the 2022 season the relationship was significant with R.H%, wind velocity and plant age. The percentage of explained variance was 38 and 84 % during the two seasons, respectively. For Empoasica spp, in the first season, the population of insect density was significantly correlated for minimum temperature, while, in 2022 season population was significant with RH% and predators. Plant age was a significant effect on the population fluctuations of A. craccivora and Empoasica spp during the second season. The percentage of Explained variance for the effect of climatic factors, and biotic factors on Empoasica spp were 75 and 74 % during the two seasons, respectively. This research aims to utilize the obtained results in developing the IPM programs against the main faba bean insect pests through activation of the effect of temperature, relative humidity and wind velocity on insect numbers.
