Research on Weakly Supervised Deep Learning Model for Semantic Segmentation of Pest and Disease Regions in Durian Blind Spots

eFood, Volume 7, Issue 4, August 2026.
Durian is a high‐value economic crop, which presents challenges in the orchards, such as complex terrain, significant canopy shading, and blind spots in manual inspections. These blind spots often become the key sources of pest and disease spread, which requires the drone‐based intelligent monitoring solution capable of operating stably in complex ...

Molecular evidence of Cacao swollen shoot virus acquisition and retention by Planococcus citri (Risso) and Pseudococcus longispinus (Targioni-Tozzetti) and Pseudococcus viburni (Signoret) Mealybugs (Hemiptera: Pseudococcidae) [PDF]

, 2018
Cacao swollen shoot virus (CSSV) remains a significant viral pathogen endemic in West African cacao-growing countries. Eradication of affected trees (complete removal) and resistance breeding in existing cacao (Theobroma cacao L.) germplasm have not ...

Ecologically Based Management of Pineapple Mealybug Wilt: Controlling Dysmicoccus brevipes Mealybug Populations with Salicylic Acid Analogs and Plant Extracts

Horticulturae
Mealybug wilt of pineapple (MWP) is a destructive disease worldwide caused by a parasitic complex that includes Pineapple Mealybug Wilt-associated Viruses (PMWaVs) and mealybugs (Dysmicoccus brevipes), which concurrently act as vectors for these viruses.

Insects and Survival: A Review of Primary and Secondary Defense Strategies

Entomologia Experimentalis et Applicata, Volume 174, Issue 7, Page 601-624, July 2026.
Based on a review of three decades of literature, insect defense mechanisms are classified into primary (I) and secondary (II) mechanisms of behavioral, morphological, and chemical nature. These mechanisms have been recorded in 22 (I) and 20 (II) orders, respectively.

Biological control of mealybugs with lacewing larvae is affected by the presence and type of supplemental prey [PDF]

, 2016
The diversity of prey and food sources in crops has a major effect on biological pest control by generalist predators. In this study, we tested if and how supplemental prey or food affects the control of the citrus mealybug Planococcus citri (Risso) by ...

Silencing Suppressor Protein p26 of Areca Palm Velarivirus 1 (APV1) Interacts With SGS3 and Promotes Its Degradation Via the Ubiquitination Pathway

Molecular Plant Pathology, Volume 27, Issue 7, July 2026.
APV1‐encoded p26 protein is a multifunctional VSR that suppresses RNA silencing and blocks the systemic spread of silencing signals. p26 interacts with host SGS3, a key component of the plant antiviral silencing pathway, and targets SGS3 for accelerated degradation via the ubiquitination pathway.

Transmission of cocoa viruses by mealybugs (Homoptera: Pseudococcidae)

Agricultural and Food Science, 1976
Several mealybug species reacted positively towards light and high humidity. Planococcoides njalensis (Laing) had a thermopreferendum at 20-25°C. and 25-33° C. was optimum for reproduction with a partial fecundity of 92 nymphs per female. T ½ biol.

Botanical compounds to combat vineyards mealybugs: An ideal alternative for organic vitiviniculture [PDF]

, 2018
The vine mealybug (Planococcus ficus) is a major pest in vineyards and is widespread in most grape-growing areas, however, to date; few organic products have been tested to combat them.

Beyond Temperature: Relative Humidity Systematically Shifts Juvenile Thermal Performance and Projected Population Growth in a Malaria Vector

Ecology Letters, Volume 29, Issue 6, June 2026.
Understanding how ectotherms respond to environmental change requires accounting for multiple interacting climatic factors; yet relative humidity is rarely integrated with temperature in trait‐based performance frameworks. Using laboratory experiments and an analytic population growth model, we show that humidity systematically modifies juvenile life ...
