An important aspect of fruit fly management is accurate information on the species and their host spectrum. Studies were conducted between October 2011 and September 2013 to determine the host range and species diversity of pest fruit flies in the northern savannah ecology of Ghana. Fruit samples from 80 potential host plants (wild and cultivated) were collected and incubated for fly emergence; 65 (81.5%) of the plant species were positive to fruit flies. From records in Africa, 11 plant species were reported to be new hosts to the African invader fly,Bactrocera invadens(Drew, Tsuruta and White, 2005). This study documented the first records ofDacus ciliatus(Loew) andTrirhithrum nigerrimum(Bezzi) in northern Ghana although both species have been previously reported in other parts of the country. Infestation byB. invadenswas higher in the cultivated fruits;Ceratitis cosyradominated in most wild fruits. Cucurbitaceae were mainly infested by three species ofDacusandBactroceracucurbitae, a specialized cucurbit feeder. Among the commercial fruit species, the highest infestations were observed in mango, tomato, sweet pepper and watermelon, whereas marula plum, soursop, tropical almond, sycamore fig, African peach, shea nut, persimmon, icacina and albarillo dominated the wild host flora. The widespread availability of host plants and the incidence of diverse fly species in the ecology call for particular attention to their impact on commercial fruits and the development of sustainable management strategies against these economically important pests in Ghana.

AbstractHostplant specialization is a major force driving ecological niche partitioning and diversification in insect herbivores. The cyanogenic defences of Passiflora plants keeps most herbivores at bay, but not larvae of Heliconius butterflies, which can both sequester and biosynthesize cyanogenic compounds. Here, we demonstrate that both Heliconius cydno chioneus, a host plant generalist, and H. melpomene rosina, a specialist, have remarkable plasticity in their chemical defence. When feeding on Passiflora species with cyanogenic compounds they can readily sequester, both species downregulate the biosynthesis of these compounds. In contrast, when fed on Passiflora plants that do not contain cyanogenic glucosides that can be sequestered, both species increase biosynthesis. This biochemical plasticity comes at a significant fitness cost for specialist like H. m. rosina, as growth rates for this species negatively correlate with biosynthesis levels, but not for a generalist like H. c. chioneus. In exchange, H. m rosina has increased performance when sequestration is possible as on its specialised hostplant. In summary, phenotypic plasticity in biochemical responses to different host plants offers these butterflies the ability to widen their range of potential host within the Passiflora genus, while maintaining their chemical defences.

Abstract This paper summarizes the different host plants and fruit flies present in two islands (Grande-Comore and Mohéli) of the Comoros Archipelago. Different exotic and wild fruit plants were sampled. Eighty plant species, potential hosts, belonging to thirty-four families were collected and incubated for the emergence of fruit flies from December 2019 to September 2020. Twenty-five plant hosts from ten families comprising cultivated and wild fruits have been identified. Fruit fly infestation rates per kilogram of fruit (T.Kg-1 ) varied from plant to plant. Exotic fruit plants, which accounted for more than half of infested plants, including Cucumis melo, Cucurbita pepo, Prunus persica, Coffea arabica and Capsicum frutescens had high infestation rates. For wild plants, the highest infestation rates have been observed in some families including Combretaceae, Cucurbitaceae, Solanaceae and Vitaceae. The highest infestation rate per kilogram of fruit was observed in a wild plant: Cyphostemma lageniflorum. Thirteen new host plants infested by Tephritidae are reported and/or listed for the first time in Comoros. In total, eight species of fruit flies identified. However, the species Bactrocera dorsalis Hendel, 1912 (47.5%) and Dacus bivittatus (Bigot, 1858) (37.6%) were the most representative of the Tephritidae that emerged.

This paper reviews the present status of all genera of Eriococcidae (Hemiptera: Sternorrhyncha: Coccoidea) known from South America and provides generic diagnoses based on the adult females of all available species for each genus. Redescriptions and illustrations are provided for the adult females of Aculeococcus morrisoni Lepage, Apiococcus gregarius Hempel, Capulinia sallei Signoret, Carpochloroides viridis Cockerell, Macracanthopyga verganiana Lizer y Trelles, Pseudocapulinia lanosa Hempel and Tectococcus ovatus Hempel, which are all type species of their respective genera. In addition, modified reproductions of original illustrations are provided for the adult females of the following species as representatives or type species of South American genera: Acanthococcus aceris Signoret, Chilechiton lynnae Hodgson & Miller, Chilecoccus browni Miller & González, Coxicoccus foldi Kozár & Konczné Benedicty, Eriobalachowskya valenzualae (Balachowsky), Exallococcus laureliae Miller & González, Hempelicoccus paranaensis (Foldi & Kozár), Icelococcus nothofagi Miller & González, Intecticoccus viridis Kondo, Melzeria horni Green, Orafortis luma Hardy, Oregmopyga neglecta (Cockerell), Poliloculus stipae González, Pseudotectococcus anonae Hempel and Stibococcus cerinus Miller & González. Descriptions and illustrations are also provided of the first-instar nymphs of: Acanthococcus aceris Signoret, Aculeococcus morrisoni, Apiococcus gregarius, A. singularis Hempel (which appears to be sexually dimorphic), Capulinia sallei, Carpochloroides viridis, Chilechiton lynnae, Exallococcus laureliae, Hempelicoccus tucumanensis (González & Granara de Willink), Icelococcus lithrae Miller & González, Melzeria horni, Oregmopyga peruviana Granara de Willink & Diaz, Pseudocapulinia lanosa, Pseudotectococcus anonae and Tectococcus ovatus. In addition, illustrated descriptions of the adult males of Capulinia sallei, Carpochloroides viridis, and Tectococcus ovatus are included. The first-instar nymphs and adult males of the other genera, where they are known, are also diagnosed and discussed. Based on the molecular studies of Cook & Gullan (2004), most species currently included in Eriococcus Targioni Tozzetti known from South America are considered to belong to the genus Acanthococcus Signoret, resulting in the following new combinations: A. clapsae (González) n. comb., A. cuneifoliae (González) n. comb., A. divaricatae (González) n. comb., A. pituilensis (González) n. comb. and A. lahillei (Leonardi) n. comb. In additon, Eriococcus pumuliae González, E. santiaguensis González & Granara de Willink and E. tucumanensis González & Granara de Willink are transferred to Hempelicoccus, as H. pumuliae (González) n. comb., H. santiaguensis (González & Granara de Willink) n. comb. and H. tucumanensis n. comb. (González & Granara de Willink). The status of Opisthoscelis prosopidis Kieffer & Jorgensen, the only species from the Neotropics currently included in Opisthoscelis Schrader, is discussed, and it is concluded that this species is unlikely to belong to this genus but is currently unrecognizable. Keys are provided for the identification of the 24 genera now known from South America based on the morphology of: (i) the adult females; (ii) the first-instar nymphs; and (iii) adult males, as far as these are known. In addition, Appendix 1 lists all Eriococcidae known from South America with their current generic placement, along with a brief summary of their host plants.

AbstractFruit flies have evolved mechanisms using olfactory and visual signals to find and recognize suitable host plants. The objective of the present study was to determine how habitat patterns may assist fruit flies in locating host plants and fruit. The tomato fruit fly, Neoceratitis cyanescens (Bezzi), was chosen as an example of a specialized fruit fly, attacking plants of the Solanaceae family. A series of experiments was conducted in an outdoor field cage wherein flies were released and captured on sticky orange and yellow spheres displayed in pairs within or above potted host or non-host plants. Bright orange spheres mimicking host fruit were significantly more attractive than yellow spheres only when placed within the canopy of host plants and not when either within non-host plants or above both types of plants. Additional experiments combining sets of host and non-host plants in the same cage, or spraying leaf extract of host plant (bug weed) on non-host plants showed that volatile cues emitted by the foliage of host plants may influence the visual response of flies in attracting mature females engaged in a searching behaviour for a laying site and in assisting them to find the host fruit. Moreover, the response was specific to mature females with a high oviposition drive because starved mature females, immature females and males showed no significant preference for orange spheres. Olfactory signals emitted by the host foliage could be an indicator of an appropriate habitat, leading flies to engage in searching for a visual image.
