Cocoa is a commercially important beverage crop that faces new challenges in the context of climate change, which can alter pest and disease dynamics in cocoa plantations. In the Dakshina Kannada district of Karnataka, India, an abrupt increase in cocoa wilt was observed during the 2017–18 and 2018–19 seasons. Systematic examination of affected trees revealed consistent attacks of (Schedl, 1951; Coleoptera:

Sucking pest management in tea (Camellia sinensis (L.) Kuntze) cultivation: Integrating conventional methods with bio-control strategies Crop Prot. (IF 2.5) Pub Date : 2024-05-24 Chitralekha Roy, Sudipta Naskar, Sanatan Ghosh, Piya Rahaman, Sweta Mahanta, Nilanjana Sarkar, Rituparna Kundu Chaudhuri, Azariah Babu, Somnath Roy, Dipankar Chakraborti
Worldwide sucking pests predominantly impact the cultivation of tea ( (L.) Kuntze), an economically significant crop. Sucking pests consume the plant sap by puncturing the vascular tissue of the host plant. Their trophic activity results in the curling of the tea leaves, followed by a dark brown or silver appearance with black spots. Sometimes, the symptom is confined to dry, dark, and dead leaves

Unwelcomed guests: Impact of deer harvest on corn and soybean wildlife damage Crop Prot. (IF 2.5) Pub Date : 2024-05-24 Christopher N. Boyer, Le Chen, Gabriela Perez-Quesada, S. Aaron Smith
While wildlife damages are a relatively small part of crop insurance claims in the United States, reported damages from wildlife are growing and producers are concerned this issue is getting worse. Wildlife agencies advocate for hunting as a control to wildlife damages to crops but to our knowledge, no study has econometrically explored if hunting could reduce crop damage. Therefore, we analyze if
