Trichoderma Strains as Biocontrol Agents [PDF]

Advancements in Genetic Engineering, 2014
In recent years there has been a growing interest in biological control of pests and diseases as a strategy for integrated pest management (IPM) of crop cultures. Species of the genus Trichoderma have been used as antagonists for the control of some of the most important phytopathogenic fungi (Fusarium oxysporum, Rhizoctonia solani, Botrytis cinerea ...

Chromosome‐scale genome assembly of the South American fruit fly, Anastrepha fraterculus sp.1

Insect Science, EarlyView.
Anastrepha fraterculus sp. 1 is a major fruit fly pest in Argentina, currently controlled through chemical treatments and traps. This study aims to enhance the genomic understanding of this species to support the development of sterile insect technique as well as the use of innovative technologies.

Iflaviruses in arthropods: when small is mighty

Insect Science, EarlyView.
Many arthropod species harbor iflaviruses, which often cause covert (asymptomatic) infections, but may still affect host fitness. We review the impact of iflaviruses on arthropod fitness, immunity, behaviour as well as the iflavirus’ host range, transmission, tissue tropism and the interactions with other microorganisms within arthropods.

Natural products as transmission-blocking agents against malaria: a comprehensive review of bioactive compounds and their therapeutic potential

Malaria Journal
Malaria eradication is hindered by the persistence of transmission stages of Plasmodium falciparum that enable parasite transfer from humans to mosquitoes.

Genetic Diversity of Whiteflies Colonizing Crops and Their Associated Endosymbionts in Three Agroecological Zones of Cameroon

Insects
Bemisia tabaci (Gennadius) is as a major pest of vegetable crops in Cameroon. These sap-sucking insects are the main vector of many viruses infecting plants, and several cryptic species have developed resistance against insecticides.

Selection, counterselection, and conditional gene expression for genetic biocontrol of insects

Insect Science, EarlyView.
Selection, counterselection, and conditional expression can be used for sex separation. Selection (S) and counterselection (CS) genes are linked to the sex chromosomes (e.g., the X and Y chromosomes) to confer sex‐specific selection or counterselection based on the presence or absence of the S or CS genes.

From the predator to the prey: a case study of the vulnerability of Harmonia axyridis to aggressive competitors

Insect Science, EarlyView.
The level of aggressiveness of an individual is a factor that shapes intraguild predation (IGP) interactions. In Nabis americoferus, high aggressiveness leads to an increase in attack rate and IGP against Harmonia axyridis. Moreover, the absence of extraguild prey seems to exacerbate IGP. In docile N.

Reduced fertilization regimes could boost biocontrol service without reducing crop yield

Insect Science, EarlyView.
Fertilization level influences pest control effectiveness in tomato crops. High fertilization increases plant growth and aphid density but reduces the performance of the parasitoid Aphidius ervi. In contrast, the predator Adalia bipunctata maintains consistent aphid suppression regardless of fertilization regime.

Potential Biocontrol Agents on Nutsedges

An-Najah University Journal for Research - A (Natural Sciences), 2000
PurpIe and yellow nutsedges are agriculturally important weeds. They have an adverse effect against a large number of cultivated crops under both protected and open field conditions. In this research, one phytophagous insect (Bactra sp., Tortricidae Lepidopterra) and two phytopathogenic fungi (Alternaria gloeosporioides) were found to be naturally ...
