Wide-ranging species cannot persist in reserves alone. Consequently, there is growing interest in the conservation value of agricultural lands that separate or buffer natural areas. The value of agricultural lands for wildlife habitat and connectivity varies as a function of the crop type and landscape context, and quantifying these differences will improve our ability to manage these lands more effectively for animals. In southern California, many species are present in avocado orchards, including mammalian carnivores. We examined occupancy of avocado orchards by mammalian carnivores across agricultural-wildland gradients in southern California with motion-activated cameras. More carnivore species were detected with cameras in orchards than in wildland sites, and for bobcats and gray foxes, orchards were associated with higher occupancy rates. Our results demonstrate that agricultural lands have potential to contribute to conservation by providing habitat or facilitating landscape connectivity.

Oviposition biology, behavior, and avocado cultivar preferences of Heilipus lauri Boheman (Coleoptera: Curculionidae).

Heilipus lauri is a specialist avocado seed feeding weevil native to parts of México and is an invasive pest in Colombia. This weevil is considered an incursion risk because possible unintended introductions into areas outside of its native range can result in establishment, which threatens avocado production in invaded regions. Despite being a well-recognized pest of avocados, relatively little is known about oviposition biology, behavior, and cultivar preferences of this weevil.

The flesh oil content (OC) is a crucial commercial indicator of avocado maturity and directly correlates with its nutritional quality. To meet export standards and optimize edible characteristics, avocados must be harvested at the appropriate stage of physiological maturity. The significant variability in OC during maturation, without any external morphological indicators, poses a longstanding challenge.

Article Synopsis
  • Phytophthora is a hemibiotrophic oomycete that causes root rot in over 5,000 plant species, impacting ecosystems and agriculture.
  • A study sequenced the genomes of two distinct isolates from California avocado orchards, revealing complex genomes with 21,111-21,402 genes and differences in virulence related to secretome and effectors.
  • The research highlights common infection strategies and host-specific adaptations of the pathogen, which could help identify key genetic factors influencing plant resistance or susceptibility.

In September 2023, thirty declining 30-year-old avocado (Persea americana) trees ('Hass' grafted on 'Zutano' seedlings) were detected in a 1.5-ha orchard in the island of Crete (Chania region). Crown symptoms encompassed wilting and leaf chlorosis, advancing to defoliation and extensive dieback.
