Abundance And Distribution

Invasion of the exotic Bactrocera dorsalis (Hendel, 1912) (Tephritidae) has drastically reduced the abundance and distribution of native Ceratitis anonae Graham, 1908 (Tephritidae) and false codling moth Thaumatotibia leucotreta (Meyrick, 1913) (Tortricidae) in Nigeria. There is an overlap in resource use among the three frugivorous insects which could result in interspecific competition. Knowledge of the population dynamics and distribution of the three frugivorous insects in the study area is lacking and such data are indispensable for effective management of the tephritid and tortricid pests. The population dynamics and distribution of the three frugivorous insects were investigated to predict the route of invasion and the outcome of interactions among the three frugivorous insects. Bactrocera dorsalis occurred in all the seven Local Government Areas (LGAs) sampled while C. anonae and T. leucotreta occurred together in two LGAs and separately in two other LGAs. The population of B. dorsalis is significantly higher than either C. anonae or T. leucotreta in the study area. The three frugivorous insects are negatively associated with one another but only the association between B. dorsalis and C. anonae was significantly different. Bactrocera dorsalis invaded the study area from southern Nigeria and C. anonae is being driven towards northern Nigeria.

AbstractThe false codling moth (FCM), Thaumatotibia leucotreta (Lepidoptera: Tortricidae) is an insect pest which represents an important threat to the production and marketing of a wide range of agricultural crops in the African-Caribbean-Pacific (ACP) countries. The FCM reduces not only the yield and quality of the crop but also as a quarantine insect pest, restricts the trade of susceptible agricultural produce on the international market. In addition, little research has been conducted in the ACP countries on the bio-ecology and sustainable management of this pest, especially on vegetables for export. Thus, action-oriented research aimed at understanding the bio-ecology of this important pest is essential to achieve effective management. Various management interventions against this pest have been used in some parts of the world, especially in South Africa on citrus. Currently, farm sanitation is regarded as the key management strategy. Exploring and improving on other interventions such as Sterile Insect Technique, monitoring and mass trapping of male moths, augmentative biological control, use of bio-pesticides, protected cultivation and cold treatment may help to mitigate the expansion of FCM into other countries, especially in the European and Mediterranean Plant Protection Organization region where it has become a regulated insect pest since 2014. This review discussed the bio-ecology of FCM and highlighted some of the challenges and opportunities for its effective management and its implication for international trade, especially the export of chillies from the ACP countries into the European Union market which requires strict phytosanitary regulations.

The egg parasitpoids Trichogrammadanausicida (Nagaraja) and Trichogrammacacaeciae (Marchal) (Hymenoptera: Trichogrammatidae), are reported for the first time in Israel. Moreover, our discovery of T.danausicida is the first report of this parasitoid species outside of India. The occurrence of those trichogrammatids was first discovered and documented in May 2016 during a survey of egg parasitoids of the False codling moth Thaumatotibialeucotreta (Lepidoptera: Tortricidae). The field survey was conducted on castor bean fruits (Ricinuscommunis) in the Israeli central coastal plain. The identity of the parasitoids was revealed by means of sequencing a portion of the cytochrome oxidase I gene (COI) of the studied parasitoids.
