This could be due to drought or uneven watering.
The images don't really identify any disease or pests. Have you had successful berry crops in the past? During fruit development, raspberries require one to 1-1-/2 inches of water (either from rain or irrigation) per week. Insufficient moisture during this time may result in small, seedy berries. During dry weather, thoroughly water raspberry plants once a week. Soak the ground to a depth of 10 to 12 inches.
