Delayed mortality, resistance and the sweet spot, as the good, the bad and the ugly in phosphine use
(2021)Phosphine is the most commonly used gas for fumigation for durable commodities globally, but there is still inadequate information regarding its efficacy in conjunction with proper concentration monitoring. In a series of ... -
Detection and geographical distribution of the organophosphate resistance-associated Delta 3Q ace mutation in the olive fruit fly, Bactrocera oleae (Rossi)
(2014)BACKGROUND The olive fruit fly, Bactrocera oleae (Rossi) (Diptera: Tephritidae), is the most important pest of olives. Its control is based mostly on organophosphate (OP) insecticides, a practice that has led to resistance ... -
Efficacy of pymetrozine against Myzus persicae and in reducing potato virus Y transmission on tobacco plants
(2010)Forty-four parthenogenetic lineages of Myzus persicae s.l. (Sulzer) from tobacco crops and peach orchards located in various regions of Greece were examined to determine their response to the insecticide pymetrozine using ... -
Evolution of imidacloprid resistance in Myzus persicae in Greece and susceptibility data for spirotetramat
(2017)BACKGROUND: Myzus persicae s.l. is a major crop pest globally and has evolved resistance to a range of insecticide classes making it increasingly difficult to control in some areas. Here we compare bioassay monitoring data ... -
Genomic structure, organization and localization of the acetylcholinesterase locus of the olive fruit fly, Bactrocera oleae
(2013)Acetylcholinesterase (AChE), encoded by the ace gene, is a key enzyme of cholinergic neurotransmission. Insensitive acetylcholinesterase (AChE) has been shown to be responsible for resistance to OPs and CBs in a number of ... -
Identification of a point mutation in the ace1 gene of Therioaphis trifolli maculata and detection of insecticide resistance by a diagnostic PCR–RFLP assay
(2015)Aphids are important agricultural pests worldwide. Their control is largely based on chemical insecticides. One species that shows important invasive abilities and host-plant-related differences is Therioaphis trifolii ... -
Insecticide resistance status of Myzus persicae (Hemiptera : Aphididae) populations from peach and tobacco in mainland Greece
(2007)The susceptibility of 88 and 38 field samples of Myzus persicae (Sulzer) to imidacloprid and deltamethrin respectively was examined using the FAO dip test bioassay. The field samples were collected from tobacco and peach ... -
Insecticide resistance status of Myzus persicae in Greece: Long-term surveys and new diagnostics for resistance mechanisms
(2016)BACKGROUND: Myzus persicae nicotianae is an important pest in Greece, controlled mainly by neonicotinoids. Monitoring of the aphid populations for resistance mechanisms is essential for effective control. RESULTS: Two new ... -
Long-term studies on the evolution of resistance of Myzus persicae (Hemiptera: Aphididae) to insecticides in Greece
(2021)The aphid Myzus persicae s.l. (Hemiptera: Aphididae) is an important pest of many crops worldwide with a complex life cycle, intensely controlled by chemical pesticides, and has developed resistance to almost all used ... -
Micro-evolutionary change in relation to insecticide resistance in the peach-potato aphid, Myzus persicae
(2010)2. Asexual organisms rely on mutation whereas sexual organisms combine mutation with recombination. 3. Few organisms provide examples of species that are both sexual and asexual, but aphids do. 4. To examine evolution on ... -
Organophosphate resistance in olive fruit fly, Bactrocera oleae, populations in Greece and Cyprus
(2007)The olive fruit fly Bactrocera oleae (Gmelin) (Diptera: Tephritidae) is the most important pest of olives in countries around the Mediterranean basin. Its control has been based mostly on bait sprays with organophosphate ... -
Scaling recovery of susceptible and resistant stored product insects after short exposures to phosphine by using automated video-tracking software
(2021)BACKGROUND: Phosphine-susceptible or resistant populations of Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae) and Rhyzopertha dominica (F.) (Coleoptera: Bostrychidae) adults were exposed to 0 (control), 1000 and ... -
Testing against umbrella or tree orderings for binomial proportions with an adaptation of an insect resistance case
(2020)Alternative hypotheses for order restrictions, such as umbrella or inverse umbrella (a.k.a tree) orderings, have been studied extensively in the literature, although less so when the studied response for each individual ... -
Transcriptomic analysis of s-methoprene resistance in the lesser grain borer, Rhyzopertha dominica, and evaluation of piperonyl butoxide as a resistance breaker
(2021)Background: The lesser grain borer, Rhyzopertha dominica is a serious pest of stored grains. Fumigation and contact insecticides play a major role in managing this pest globally. While insects are developing genetic ... -
Tribolium castaneum: A Model Insect for Fundamental and Applied Research
(2022)Tribolium castaneum has a long history as a model species in many distinct subject areas, but improved connections among the genetics, genomics, behavioral, ecological, and pest management fields are needed to fully realize ...
