“…As for I. aegyptiaca, it was also observed in West Africa, Asia and Oceania [11]. Species diversity of mango mealybugs revealed in this study is relatively limited as compared to the 10 species of the same families reported on the mango tree in the North and Central regions of Benin [9]. Ferrisia virgata and I. aegyptiaca populations' densities were very low during the study period.…”

Rastrococus invadens was the only reported mealybug species on the mango tree in Western Burkina Faso. This study aimed at carrying out the inventory and showing the importance and distribution of other mealybug species associated with the mango tree. It was also important to determine the periods of abundance of these species vis-a-vis R. invadens. For this purpose, the density of mealybugs was assessed in three study sites (Toussiana, Bérégadougou and Orodara) in Western Burkina Faso. The observations were made from June 2014 to June 2015 at a frequency of 15 ± 1 days. They focused on 20 leaves (5 leaves/cardinal point) levied on each mango tree. The species identified as Ferrisia virgata Cockerell and Icerya aegyptiaca Douglas were collected from mangos infested by R. invadens representing 98% -99% of the density of the observed mealybug species. The periods of abundance of F. virgata and I. aegyptiaca were respectively the dry season and the rainy season. The effect of temperature, relative humidity and rainfall on the populations of F. virgata and I. aegyptiaca was also discussed. These results highlight the distribution range of F. virgata and I. aegyptiaca worldwide including Burkina Faso. R. invadens was the main mealybug species on mango in Burkina Faso in general and in the Western region of the country in particular.

“…Further, secretions of extra-floral and floral nectars by host plants and the presence of hemipteran trophobionts on these host plant may favor the development of the ants (Kenne et al, 2003). Mango trees in the Sudanian area of Benin were reported to harbor large numbers of scale insects (12 species) particularly on mango fruit petioles and on the fruits (Germain et al, 2010). In contrast, Vayssières (2012) recorded only two Hemiptera species on cashew in northern Benin.…”

Weaver Ant Oecophylla longinoda Latreille (Hymenoptera: Formicidae) Performance in Mango and Cashew Trees Under Different Management Regimens

Weaver ants are used for biological control of insect pests in plantation crops. To obtain proper pest control, ant densities need to be high. Food availability and nesting facilities on host plants and management practices may affect ant performance. In the present study, we tested the effect of two host plant species (mango and cashew) and three different management practices (ants only, ants fed with sugar and ants combined with the soft chemical insecticide Spinosad) on weaver ant performance. Performance was assessed over a 22 month period, as an index value based on the number of ant trails per tree and as the number of ant nests per tree. A total of 216 trees (72 per treatment) were observed in each crop. In all treatments, the ants performed better in mango compared to cashew. Using the index based performance measure, ants also performed better in the sugar treatment as compared to the two other treatments, whereas this was not the case in cashew. We conclude that sugar feeding can be used to increase ant populations in mango. We also found that the treatment with Spinosad in combination with ants showed performance equal to the treatments with only ants, suggesting that Spinosad did not negatively affect ant populations. We therefore conclude that Spinosad is compatible with the use of weaver ants in integrated pest management programs.

“…In Italy, Pellizzari (2007) reports that C. aonidum, although it was already registered as an enemy of Dracaena and Kent'ta in greenhouses, it was found to be acclimatized in Calabria on citrus outdoors in 2006. It is also recently IS ENTOMOLOGIA HELLENICA 16 (2005-2006 reported as a new pest in greenhouses in (Germain and Matile Ferrerò 2005) and the Hungary (Reiderne and Kozàr 19941.

The presence of the scale insect Chrysomphalus aonidum (Linnaeus) (Hemiptera: Diaspididae), (the Florida red scale) is recorded in Greece and some data on its morphology are given. The coccid was found on the ornamental plant Dracaena sp. in Athens in the year 2000 and its rearing on potato tubes (Solanum tuberosum) and Cucurbita maxima is possible in the insectary. In January 2007 C. aonidum was found on heavily infested Citrus limon and Citrus sinensis, as well as on the less infested ornamental bushes Ficus benjamina and Ligustrum japonicum in outdoor conditions in the city of Kalamata (Peloponnese-southern Greece). In the past the presence of C. aonidum was recorded in Greece, but it was considered an occasional pest of citrus due to its difficulty to become acclimatized.
