Bactrocera invadens Drew, Tsuruta & White (Diptera: Tephritidae) invaded Kenya in 2003. Before the arrival of B. invadens, indigenous fruit fly species Ceratitis cosyra (Walker) was predominant pest mango (Mangifera indica L.). Within 4 yr invasion, has displaced C. and become mango, constituting 98 88% total population traps at Nguruman, respectively. We tested two possible mechanisms responsible for displacement namely; resource competition by larvae within aggression between adult flies....
Fruit flies are a major threat to the horticulture industry in Africa owing their damage incidence and economic losses fruit vegetable crops, quarantine implications. Numerous studies with different research interests have been conducted on throughout African continent. Despite these studies, there is little knowledge among stakeholders about fly pests terms of economically important species, pest status, impact control strategies. These parameters prerequisites designing management...
A species in the Bactrocera dorsalis (Hendel) complex was detected Kenya during 2003 and classified as invadens Drew, Tsuruta & White. Having spread rapidly throughout Africa, it threatens agriculture due to crop damage loss of market access. In a recent revision B. complex, incorporated into dorsalis. The potential distribution has been previously modelled. However, previous models were based on presence data did not incorporate information seasonal phenology dorsalis, nor possible...
The need to evaluate the human health safety of fishery resources remain urgent in mist ever-increasing fear heavy metal toxicity from consumption Ghana's fisheries resource, as a consequence pollution several anthropogenic activities including artisanal gold mining. Nevertheless, bigeye grunt (Brachydeuterus auritus) and Bagrid catfish (Chrysichthys nigrodigitatus) commercially valuable fish species West Africa continue attract high patronage.Forty-five specimens each C. nigrodigitatus B....
Abstract Mango is a delicious tropical fruit with high economic value worldwide. The Forest-Savanna Transition zone of Ghana contributes significantly to the production mangoes for both local and international markets. plagued fly ‘menace’ like all mango-producing areas in Ghana. Not much has been done terms species monitoring. A 24- month monitoring survey was conducted eight mango orchards, assess composition flies associated their damage levels. Four para-pheromone attractants (Methyl...
Abstract The predominantly Afrotropical fruit fly genus Ceratitis contains many species of agricultural importance. Consequently, quarantine is a major concern for governmental regulatory agencies. Although diagnostic keys exist identification all described species, these tools are based on adult characters. Flies intercepted at ports entry usually immatures, and cannot be diagnosed larval morphology. To facilitate pests entry, this study explores the utility DNA-based select group related...
This study investigated the effects of temperature on development immature stages Anopheles gambiae (s.l.) mosquitoes.Mosquito eggs were obtained from laboratory established colonies and reared under eight regimes (25, 28, 30, 32, 34, 36, 38 40°C), 80 ± 10% relative humidity. Larvae checked daily for to next stage mortality. Pupation success, number adults produced sex ratio newly emerged recorded. Larval survival was monitored every 24 h, data analysed using Kaplan-Meier analysis. Analysis...
Abstract Background Malaria remains one of the most devastating diseases globally, and control mosquitoes as vector is mainly dependent on chemical insecticides. Elevated temperatures associated with future warmer climates could affect mosquitoes' metabolic enzyme expression increase insecticide resistance, making difficult. Understanding how mosquito rearing influence their susceptibility to enzymes aid in development novel tools strategies a climate. This study evaluated effects...
Larvae of black soldier fly (BSF), Hermetia illucens (L.1758) (Diptera: Stratiomyidae), are increasingly being used as animal feed ingredients. usually produced by placing eggs, obtained from adult rearing on growing substrates but can also be exposing to naturally occurring BSF females. In the latter system, substrate needs not only nutritious for larvae attractive females oviposition. The ‘preference-performance principle’ suggests that female insects prefer oviposit in maximise offspring...
Abstract Morphometric studies of five allopatric parasitoid populations (genus Psyttalia Walker) from coffee plantations in Cameroon (Nkolbisson), Ghana (Tafo) and Kenya (Rurima, Ruiru Shimba Hills) one non-coffee population (from Muhaka, Kenya) were compared with individuals concolor (Szépligeti), a species released several biological control programmes the Mediterranean Region since 20th Century. Analyses wing vein measurements showed second submarginal cell fore its adjoining veins had...
The life cycle of the invasive alien insect pest, fall armyworm (FAW), Spodoptera frugiperda (J.E. Smith), was studied using a colony established from field-collected larvae. Eggs, neonate larvae, and newly emerged adult moths were used in experiments to investigate basic biology FAW. Adult females laid up 1184 eggs with mean 469 ± 22 per female. incubation period percentage hatchability 2-3 days 80–87%, respectively. larval lengths first sixth instar 4.63, 6.60, 9.76, 15.86, 25.13, 27.81...
Higher temperatures expected in a future warmer climate could adversely affect the growth and development of mosquitoes. This study investigated effects elevated on longevity, gonotrophic cycle length, biting rate, fecundity, body size Anopheles gambiae (s.l.) (Diptera: Culicidae) eggs obtained from laboratory established colonies were reared under eight temperature regimes (25, 28, 30, 32, 34, 36, 38, 40°C), 80 ± 10% RH. All adults allowed to feed sugar solution soaked cotton wool; however,...
The seasonal abundance of African Invader fly, Bactrocera invadens and the influence temperature rainfall on fly catches was determined in two agro ecological zones; moist semi-deciduous forest area coastal grassland Volta Region Ghana for year mango production. Traps containing methyl eugenol were used monitoring Africa invader where data both collected from Meteorological Services region. A total 49,322 organisms captured, 45,829 identified as 3493 non-fruit fly. There significant...
