Kilimanjaro,...

Abstract BACKGROUND The cotton jassid, Amrasca biguttula , a dangerous and polyphagous pest, has recently invaded the Middle East, Africa South America, raising concerns about future of other food crops including okra, eggplant potato. However, its potential distribution remains largely unknown, posing challenge in developing effective phytosanitary strategies. We used an ensemble model six machine‐learning algorithms random forest, maxent, support vector machines, classification regression...

Temperature is an important factor determining the abundance, distribution and diversity of termite species. Thus, termites are affected by changing climate have to adopt different means surviving in order avoid extinction. Using occurrence data, bioclimatic variables vegetation cover, we modelled predicted current future habitat suitability for mound-building Nigeria. Of 19 index (NDVI) tested, only six were significant eligible as predictors Macrotermes subhyalinus M. bellicosus. Under...

The tomato leafminer, Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) is an invasive pest that devastates the production of tomatoes and other solanaceous vegetables. Since its trans-Atlantic invasion in 2006, T. has spread established many countries across Afro-Eurasian Supercontinent, causing huge yield losses. This study aimed to determine relationship between temperature life history traits provide thermal thresholds for development using cycle modelling. Linear non-linear models were...

Scapsipedus icipe Hugel and Tanga (Orthoptera: Gryllidae) is a newly described edible cricket species. Although, there substantial interest in mass production of S. for human food animal feed, no information exists on the impact temperature their bionomics. Temperature-dependent development, survival, reproductive life table parameters was generated integrated into advanced Insect Life Cycle Modeling software to describe relative population increase spatial spread based nine constant...

Although the coffee berry borer, Hypothenemus hampei (Ferrari) (Coleoptera: Curculionidae: Scolytinae) is most destructive insect pest of worldwide, there much to learn about its thermal biology. This study aimed develop temperature-based models for H. development and provide requirements immature stages in laboratory. Using a new observation method, larval survival were monitored daily on fresh Arabica seeds, under seven constant temperatures range 15-35°C, with 80 ± 5% RH 12:12 L:D...

The braconid wasp, Diachasmimorpha longicaudata (Ashmead), was introduced in Kenya from Hawaii for classical biological control of the invasive tephritid, Bactrocera dorsalis Hendel. Following reports that D. had formed new associations with Ceratitis cosyra, laboratory experiments were conducted to assess interaction between and native parasitoid C. cosyra; Psyttalia cosyrae (Wilkinson) under three scenarios: B. only, cosyra only mixed populations two species. Parasitoids host as sole,...

Abstract BACKGROUND The white mango scale, Aulacaspis tubercularis (Hemiptera: Diaspididae), is an invasive pest that threatens the production of several crops commercial value including mango. Though it important pest, little known about its biology and ecology. Specifically, information on habitat suitability A. occurrence potential distribution under climate change largely unknown. In this study, we used four ecological niche models, namely maximum entropy, random forest, generalized...

Phthorimaea absoluta (Meyrick) (= Tuta absoluta) (Lepidoptera: Gelechiidae), is the most damaging insect pest threatening production of tomato and other solanaceous vegetables in many countries. In this study, we predicted risk establishment number generations for P. current future climatic conditions under two Shared Socioeconomic Pathways (SSP2-4.5 SSP5-8.5) years 2050 2070 using life cycle modelling (ILCYM) software. We used a temperature-dependent phenology model to project three indices...

Abstract The African citrus triozid (ACT), Trioza erytreae Del Guercio (Hemiptera: Triozidae), is the major vector of ‘ Candidatus Liberibacter africanus’, associated with greening disease [huanglongbing (HLB)]. Although T. a very destructive pest in production yield losses up to 100%, there limited information on its thermal biology, which prerequisite for developing an environmentally friendly management strategy. This study investigated effect temperature development and survival under...

Temperature critically affects the performance of entomopathogenic fungi (EPF). Mathematical models are critical tools used in predictive microbiology but less adopted for EPF. We selected eight nonlinear to describe thermal biology; minimum (Tmin), optimal (Topt) and maximum (Tmax) thresholds; maximal growth (Pmax) Conidial germination mycelial Metarhizium anisopliae (ICIPE 7, ICIPE 20, 62, 69, 78) Beauveria bassiana 284) isolates incubated at 12, 16, 24, 28, 32 36°C were measured fitted...

The braconid parasitoid Diachasmimorpha longicaudata (Ashmead) (Hymenoptera: Braconidae) is one of the most important natural enemies in classical biological control programs against tephritid fruit flies worldwide. In light spread invasive fly species, Bactrocera dorsalis Africa and beyond, there a need to implement control. current study aimed determine temperature thresholds for D . reared on B , using life cycle simulation modeling guide informed releases Africa. Simulated parameters...

There are various postharvest treatments currently available in the market. Among these, heat-based very effective. Several hot water treatment (HWT) protocols at temperature regimes and time durations have been developed for different mango cultivars varieties. However, many concerns raised regarding quality of fruits subjected to HWT, particularly on physical biochemical properties. The purpose this study was generate empirical evidence effect HWT protocol recognized accepted by EU Apple...

The coffee berry borer, Hypothenemus hampei Ferrari (Coleoptera: Curculionidae, Scolytinae), is the most devastating insect pest of worldwide.
