  author={Daniel Blumberg and Moshe Kehat},
The date stone beetle,Coccotrypes dactyliperda F. (Coleoptera: Scolytidae), is a primary pest of green unripe dates. The adult beetle chews a characteristically round hole in the fruit, which results in the druit dropping 1 or 2 days later. Egglaying and entire development occur within galleries produced by the female in the date stone; males are unable to penetrate the stones. In laboratory cultures and in field-collected date stones, the beetle adult females were predominant (85-93… Expand

Oogenesis in the date stone beetle, Coccotrypes dactyliperda, depends on symbiotic bacteria
It is suggested that symbiotic bacteria are not involved in female‐biased sex ratios but are required for oogenesis in C. dactyliperda, and the specific role each of the bacteria plays in the oogenesis remains to be determined. Expand
Biology, ecology and distribution of the Date Stone Beetle, Coccotrypes dactyliperda (Coleoptera: Curculionidae)
Coccotrypes dactyliperda is a comparatively long-lived Coleoptera species that has proven to be highly adaptable at infesting seeds of a wide range of palm species and thus was able to become naturalised in most subtropical and warm temperate environments. Expand
Association of the borer Spermophthorus apuleiae (Coleoptera; Curculionidae; Scolytinae) with the "pau-ferro" tree Caesalpinia ferrea (Leguminosae)
The data suggest that S. apuleiae is a frugivorous species which peculiarly does not eat seeds of "pau-ferro", and when beetles were exposed to seeds as the only source of food they were incapable of boring or eating the seeds and died. Expand
Review: Date palm arthropod pests and their management in Israel
The key pests in date plantations in Israel are the lesser date moth and sap beetles in most of the date-growing areas, and spider mites which are restricted to the Arava Valley, and future management of the first two should rely on an improved monitoring system and integration of pheromone application for reduction of the population and damage.

Natural History and Ecology of Bark Beetles
Their population dynamics are characterized by cross-scale interactions, density-dependent feedbacks, plasticity in host selection decisions, critical thresholds at multiple levels of interaction, and multi-equilibria. Expand

First Record of Four Scolytid Species (Coleoptera: Curculionidae) in the Balearic Islands (Western Mediterranean; Spain)
The main objective of this study is to present four scolytid species reported in Majorca for the first time: Chaetoptelius vestitus, Coccotrypes dactyliperda, Xylocleptes bispinus and Xyleborus eurygraphus to increase the knowledge of this coleopteran group with specific importance on forestry management in Mediterranean conditions. Expand
Time limitation affects offspring traits and female's fitness through maternal oviposition behaviour
It is proposed that, in order to compensate for the loss of time, mothers that experienced a shortage of oviposition sites influence their offspring to mature faster at the cost of a smaller than average body size. Expand
An equal sex ratio followed by differential sex mortality causes overestimation of females in gall midges: no evidence for sex ratio regulation
It is shown that adult males emerge up to 1 day earlier and have shorter life span than females and that the arrhenogenic/thelygenic gall midges are not able to alter the number of their male/female progenies in response to changes in environmental conditions. Expand


Fruit drop and damage in dates: the role ofcoccotrypes dactyliperda F. and nitidulid beetles, and prevention by mechanical measures
The extent of fruit drop and damage inflicted to date fruit byoccotrypes and nitidulids was estimated and control measures were investigated, and the mechanical control method was preferable. Expand
Integrated control of date palm pests in Israel
An integrated control program for successful pest management of date palms in Israel has resulted in a drastic decline of the P. blanchardi population and in successful and easy control of the other pests. Expand
