Shell discoloration of pistachio (Pistacia vera) nuts collected from commercial orchards and processing plants was related to fungal decay and insect infestation of the kernel. Nuts with ruptured hulls (early split nuts and nuts with cracked hulls) varied considerably in the amount of shell discoloration, ranging from none to extensive. For both types of hull rupture, as shell discoloration increased, kernel decay also increased. Nuts with no discoloration had little or no fungal decay and navel orangeworm (Amyelois transitella) infestation. Processed nuts with an oily-shell appearance had the highest incidences of fungal decay and navel orangeworm infestation; nuts with a crinkled shell, nuts with extensive dark brown discoloration, and nuts with moderate dark brown discoloration along the suture had relatively high levels of decayed and infested kernels; while nuts with yellow discoloration, nuts with moderate dark brown discoloration not along the suture, and nuts with no discoloration had little or no decay and infestation. Also, as shell discoloration of processed nuts increased, kernel decay increased. Our results suggest that shell characteristics may be used by processors to identify poor quality nuts and to improve the quality of pistachio nuts sold to consumers.

Growth Of Fungi

Development of larvae of the navel orangeworm, Arn.ielois transitella (Walker) (Lepidoptera: Phycitidae), was studied under various photoperiods, temperatures and larval diets, in an effort to induce dormancy. Ready – to – batch eggs or neonate larvae were placed in transparent vials half – full of diet. Fully grown larvae not pupating within 14 days at 26.7oC and L:D 16:8 were considered as being in dormancy. With artificial larval diets containing bran, yeast, vitamins, and fortified or not with a high protein cereal and egg yolk, none of the treatments induced dormancy to a substantial percentage of laboratory stock or wild larvae. With dry walnut meats, larval growth was slower and survival much lower than with the artificial diets. With walnut meats, when eggs were incubated at 32.2oC and L:D 0:24, a certain percentage of grown larvae of the laboratory stock underwent dormancy when grown as larvae under the conditions that follow: 40% at 21oC and L:D 12:12, 17% at 21oC and L:D 0:24, 19% at 26.7oC and L:D 16:8, and 22% at 26.7oC and L:D 0:24 for the first 14 days than at 21oC and L:D 8:16 for the rest of larval life. When both embrya and larvae developed at 21oC and L:D 0:24, 17% of the larvae underwent dormancy. Yet, the relatively small number of grown larvae in the groups fed walnut meats suggests further work for the occurrence of dormancy in this insect to be proven. No larvae developed on straight brewers’ yeast powder. Straight soybean flour or 9:1 and 7:3 mixtures of it with yeast powder allowed the production of grown larvae, pupae and adults of normal appearance. The rate of larval growth on the soy:yeast diets was significantly slower than on a reference diet. At 26.7oC, a L:D 16:8 photoperiod was as good as a 14:10 one. Continuous darkness resulted in significantly reduced yield in adults and rate of larval growth. High relative humidity on the surface of the diet allowed excessive growth of fungi on and in the soy:yeast diets and resulted in a much faster larval growth. Larvae developed well on dry walnut meats and in cracked dry and water-soaked walnuts. Inside the walnuts the rate of larval growth was uneven, some larvae being still fairly small on the 53rd day at 26.7oC, while the majority was fully grown or had already pupated.

Monitoring Traps

Abstract The use of aerosol mating disruption for management of the navel orangeworm Amyelois transitella (Walker) in California tree nuts has increased markedly. This treatment suppresses pheromone monitoring traps in neighboring orchards as well as in the orchard under treatment. The current study, therefore, addresses the interrelated topics of which attractant is most effective, how the number of adults captured is affected by trap design, and what sex is captured. Under most circumstances, wing traps baited with phenyl propionate (PPO) captured more adults than those baited with a 5-compound kairomone blend. Adding a pheromone lure along with the dispenser for the experimental attractant increased the number of adults captured with PPO both in and near-mating disruption. In contrast, addition of a pheromone lure along with the kairomone blend only increased the number of adults captured in orchards near but not under mating disruption. Delta traps, which are preferred by the industry, captured fewer adults than wing traps. Improvements in the number of adults captured with PPO in delta traps from addition of a pheromone lure and from design modifications were additive. Both sexes were captured by all attractants and trap designs tested, and the sex ratio was highly variable. Open traps like the wing trap captured a slightly higher proportion of males than closed traps. These findings are discussed in the context of management of the navel orangeworm.
