Biological Pesticides as Viable Alternative to Synthetic Pesticides for Sustainable Agriculture and Nutrition: A Systematic Review

open access: yesJournal of Sustainable Agriculture and Environment, Volume 5, Issue 2, June 2026.
ABSTRACT The overuse of synthetic pesticides in agriculture has raised significant environmental and health concerns. Biopesticides have emerged as viable, environmentally compatible alternatives. However, recent comprehensive reviews integrating all biopesticide categories and emphasizing their contribution to synthetic‐pesticide‐free and health‐safe ...

COTTON FRUITING COMPONENTS IN RELATION TO PINK BOLLWORM INFESTATION [PDF]

open access: yesJournal of Plant Protection and Pathology, 2003
The relation between the number of squares, blooms and green bolls on cotton plants and pink bollworm infestation during the cotton seasons of 2001 and 2002 at Kafr EI-Sheikh Governorate was studied.

Molecular mechanisms of sex determination in Lepidoptera: current status and perspectives

open access: yesInsect Science, Volume 33, Issue 2, Page 599-617, April 2026.
The genetic basis of sex determination in Lepidoptera was discovered in 2014 in the silkworm Bombyx mori. In this model species, the W chromosome‐derived small piRNA called Fem piRNA downregulates the expression of a Z‐linked gene, Masculinizer (Masc), which leads to the default female‐specific splicing of the doublesex gene (dsxF) and thus to female ...

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

open access: yesInsect Science, Volume 33, Issue 2, Page 586-598, April 2026.
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 ...

Synthetic biology approaches to generate temperature‐sensitive alleles for the Sterile Insect Technique

open access: yesInsect Science, Volume 33, Issue 2, Page 517-532, April 2026.
Abstract The Sterile Insect Technique (SIT) is an environmentally friendly, sustainable pest control approach, which uses large‐scale releases of sterile insects to suppress or eradicate target populations through infertile matings. The efficiency of SIT is enhanced by male‐only releases requiring genetic sexing strains (GSSs) that are classically ...

The Ambiguous Ecologies of Agri‐Alternatives: Exploring the Calculus of Social Reproduction in Rural India

open access: yesJournal of Agrarian Change, Volume 26, Issue 2, April 2026.
ABSTRACT This paper advances scholarship on agri‐alternatives by probing the gap between romanticised narratives of how alternative farming transitions ought to be and the actual practices farmers enact in their fields. Focusing on moments when such alternatives encounter on‐the‐ground realities, we propose ambiguous ecologies as a lens to explore the ...

Electromechanical Microinjection of Pink Bollworm Pectinophora gossypiella Embryos Increases Survival

open access: yesBioTechniques, 1997
We report and compare methods and apparatus for injection of pink bollworm, Pectinophora gossypiella (Saunders), embryos. Injection with an electromechanical device resulted in 59% survival of embryos.

Role of mitochondrial complex I genes in host plant expansion of Bactrocera tau (Tephritidae: Diptera) by CRISPR/Cas9 system

open access: yesInsect Science, Volume 33, Issue 1, Page 147-158, February 2026.
The role of 3 mitochondrial complex I gene in host expansion of Bactrocera tau was verified by CRISPR/Cas9 gene editing system. A stable homogenous strain (Btndufa7‐/‐) of B.tau was established after silencing Ndufa7. The reduced size of larvae and pupae of Ndufa7 knockout strain was first found.Then different levels of fitness and relative expression ...
