Biopesticides as Promising Alternatives to Chemical Pesticides: A Review of Their Current and Future Status

, 2020
Biopesticides are living organisms or natural products that control agricultural pests including bacteria, fungi, weeds, viruses and insects. Biopesticides can be classified into different categories, such as microbial pesticides, plant-incorporated ...

Phytotoxicity of Essential Oils: Opportunities and Constraints for the Development of Biopesticides. A Review

Foods, 2020
The extensive use of chemical pesticides leads to risks for both the environment and human health due to the toxicity and poor biodegradability that they may present.

DsiRNA‐mediated silencing of Ceratitis capitata transformer or transformer‐2 leads to masculinization of XX embryos and systemic gene silencing in ovaries

Insect Science, EarlyView.
We carried out functional studies using Dicer‐substrate small interfering RNAs (DsiRNAs), targeting the sex determination genes Cctransformer (Cctra) and Cctransformer‐2 (Cctra‐2) in the Mediterranean fruit fly (Ceratitis capitata). Microinjection of DsiRNAs into XX embryos (0‐1 h old) rapidly triggered the expression of male‐specific Cctra isoforms ...

Evaluating the Efficacy of Organic Approved Fungicides for the Control of Powdery Mildew in Squash [PDF]

, 2016
Powdery mildew grows well in environments with high humidity and moderate temperatures and can be problematic on crops in the Northeast. Cucurbit crops face powdery mildew and often downy mildew on a yearly basis and significant yields losses have been ...

Toxicity and Risk of Biopesticides to Insect Pollinators in Urban and Agricultural Landscapes

Agrochemicals
Pollinators play important roles in providing pollination services, maintaining biodiversity, and boosting crop production. Even though pollinators are essential to the environment and agriculture, their decline has been noted across multiple studies in ...

Neoclassical development of genetic sexing strains for insect pest and disease vector control

Insect Science, EarlyView.
The sterile insect technique has been effectively used for decades, and an important component is the availability of sex separation systems, in particular genetic sexing strains. Classical approaches, such as irradiation‐induced chromosomal translocations, have yielded stable strains for species like the Mediterranean fruit fly.

First report of Metarhizium anisopliae IP 46 pathogenicity in adult Anopheles gambiae s.s. and An. arabiensis (Diptera; Culicidae). [PDF]

, 2009
The entomopathogenic fungus Metarhizium anisopliae isolate IP 46, originating from a soil sample collected in 2001 in the Cerrado of Central Brazil, was tested for its ability to reduce the survival of adult male and female Anopheles gambiae s.s. and An.

A systematic review on research trends and commercialised entomopathogenic nematodes: A global perspective

Agricultural and Forest Entomology, EarlyView.
Out of 136 identified EPNs, only 18 (8 Steinernema and 6 Heterorhabditis) are commercialised globally, highlighting a major gap between discovery and application. High production costs and inconsistent field efficacy are the leading obstacles to the widespread commercialisation of EPN‐based biocontrol products.
